Smart Dustbins: Transforming Waste Management in Smart Cities

Abstract

In light of India's groundbreaking smart city project, it is imperative to revolutionize the waste collection system for these intelligent urban centers. To accomplish this, ensuring convenient accessibility to garbage disposal points and implementing an optimized collection process are vital for efficient resource utilization in terms of time and fuel.

Introduction

 

Many urban cities and towns in India suffer from inadequately designed systems for proper garbage disposal and collection. Moreover, the rapid urbanization is exerting immense pressure on the existing infrastructure, which is unable to keep up with the pace of expansion. To meet the demands of the government's visionary smart city initiative, which leverages IT-enabled solutions, it becomes crucial to establish a cleaner environment. Our proposed system presents an IT-driven solution that enhances garbage collection efficiency, streamlines disposal planning, and generates comprehensive data on garbage generation. The system effectively addresses three pivotal challenges:

 

1) Enhancing accessibility to public dustbins for efficient garbage disposal.

 

2) Optimizing time and fuel consumption through an efficient collection process.

 

3) Collecting data to assess the volume of garbage generated by cities, facilitating informed disposal planning.

 

Description

 

Our proposed system consists of three layers:

 

1) Dustbin Layer:

This layer incorporates internet and Wi-Fi-enabled dustbins equipped with advanced sensors. These sensors accurately monitor the fill status of the dustbins and periodically transmit the data, including GPS location, to the server.

 

2) Server Layer:

The server collects and processes information regarding the fill status and location of the dustbins. It promptly responds to client queries, providing the nearest dustbin location and offering detailed directions for access.

 

3) Client Layer:

Clients can conveniently request information about the nearest IT-enabled dustbin location from the server using a dedicated mobile application.

Working Principle of an Intelligent Dustbin

 

To determine the fill status of a dustbin, we employ the following formula, where X represents the fill status, T denotes the time duration between wave generation and reception, and C symbolizes the speed of light:

 

X = L - (CT)/2

 

Likewise, the percentage of fill-up is calculated using the following formula:

 

P = (X/L) * 100

 

It is assumed that the wave path is almost vertical.

Implementation

 

To optimize the garbage collection process from these dustbins, we propose the utilization of the following scheduling algorithms:

 

1) Fixed Scheduling:

This approach involves establishing a predetermined collection interval, such as every three days. The Traveling Salesman Problem algorithm can be employed to plan the collection route effectively.

 

2) Priority Scheduling:

Dustbins are prioritized for collection based on their decreasing fill status. For instance, if we have three dustbins with fill statuses of 92%, 80%, and 96%, the collection order would be 96%, 92%, and then 80%.

 

3) Average Threshold Scheduling:

In this approach, we calculate the average fill status of all dustbins. If the average exceeds a predefined threshold, such as 70%, the collection process is scheduled. Within this scheduling framework, the collection order can be determined either by employing the Priority Scheduling or the Traveling Salesman Problem approach.

 

4) Full Dustbin Capacity Utilization Scheduling:

Collection is carried out only when all dustbins have reached their full capacity. Once again, the Traveling Salesman Problem algorithm can be utilized to plan an optimal route.

Advantages

 

1. Our system ensures enhanced accessibility to dustbins, thereby significantly improving the overall waste management process.

 

2. In the event of a dustbin being relocated, our system automatically updates the server with the new GPS location, ensuring accurate information retrieval.

 

3. By implementing effective route planning, our system optimizes fuel consumption and saves valuable time. The Traveling Salesman Problem algorithm can be employed to accomplish this goal.

 

4. Through reduced fuel consumption, particularly of diesel and petrol, our system actively contributes to minimizing pollution and promoting a cleaner environment.

 

5. The data provided by our IT-enabled dustbins facilitates better planning and design of the waste collection process. Monthly estimates of current garbage disposal levels can be obtained, empowering decision-makers with valuable insights.

 

Conclusion

 

One notable advantage of our system lies in the government's ability to leverage garbage generation statistics for policy and program design. By effectively implementing this system, we can make significant strides towards cleaner, greener cities, thereby transforming the vision of smart cities into a tangible reality.

Scrum Methodology: Empowering Agile Software Development Through Human Agility

Abstract:

In recent years, the software community has engaged in pivotal discussions surrounding agile methodologies, including Scrum and Extreme Programming (XP). These methodologies have gained significant traction for their emphasis on human agility and return on investment, particularly in small to medium-sized projects characterized by dynamic requirements. However, critics have expressed concerns about their effectiveness. This article provides a comprehensive review of Scrum, delving into its framework, artifacts, and ceremonies, while offering valuable insights for beginners seeking to grasp the Scrum Methodology.

 

Introduction:

Scrum, conceived in 1986 by Hirotaka Takeuchi and Ikujiro Nonaka in the context of the New Product Development Game, stands as an incremental and iterative agile software development framework that revolutionizes the process of product development. By challenging the conventional sequential approach, Scrum fosters a flexible and holistic strategy that unites development teams to accomplish a common objective. It encourages self-organization, close online collaboration, and face-to-face communication among team members, transcending disciplinary boundaries.

At the heart of Scrum lies its recognition of "requirements volatility," acknowledging the potential for customers to alter their preferences and needs during the production process. This inherent unpredictability poses challenges that cannot be easily overcome through traditional predictive approaches. In response, Scrum embraces an empirical approach, focusing on responding to emerging requirements, adapting to evolving technologies, and navigating market dynamics.

 

Fundamental to Scrum are real-time decision-making processes based on actual events and information. This necessitates the formation of specialized teams capable of self-management, effective communication, and informed decision-making. While applicable to various projects, Scrum finds its most common usage in software development, particularly in projects characterized by rapidly changing or highly emergent requirements.

 

Distinctive Features of Scrum:

Scrum serves as a powerful tool and framework for constructing intricate products. It offers a flexible product development strategy that does not impose specific engineering practices, people management methodologies, or risk management approaches. While Scrum does not explicitly define engineering practices, it accommodates the integration of non-Scrum practices that contribute to its success. For instance, test-driven development has proven effective in agile projects, even though it is not an explicit Scrum practice. The essence of Scrum lies in its provision of feedback, enabling continuous process improvement. By intelligently analyzing the outcomes and making informed decisions based on transparency, Scrum practitioners can optimize results and achieve remarkable success.

 

Scrum Practices and Roles:

The "Scrum Guide" by the Scrum Alliance provides a formal definition of Scrum, while Tests created by Sutherland, Vodde, and Silver serve as tools to assess the validity of Scrum implementations. Although Scrum is often adopted in its entirety, some organizations tailor it to suit their specific needs. However, caution must be exercised to ensure reasonable adaptations that align with the original methodology. Inappropriate variations are referred to as "ScrumButs." As a knowledge bundle, Scrum is best adopted as a whole, as fragmented or improper adoption is unlikely to yield the expected benefits.

The development process in Scrum is characterized by fixed-length iterations known as sprints. These sprints, lasting a month or less, involve the construction and delivery of the product for feedback. Only the Product Owner possesses the authority to cancel a sprint. Regular milestones instill a sense of tangible progress, inspiring the team while allowing early detection of shortcomings or misunderstood requirements. Short iterations also reinforce the importance of accurate estimation, which often poses challenges in traditional waterfall projects.

 

Scrum Roles:

Unlike classical project management methods, Scrum does not necessitate positions such as a product manager, task manager, or team leader. Instead, Scrum introduces three coequal roles:

1. Product Owner: The Product Owner assumes responsibility for the product's vision, requirement gathering, prioritization, budget control, and return on investment (ROI).

 

2. Scrum Master: As the champion of Scrum within the team, the Scrum Master ensures the enactment and enforcement of Scrum values, practices, and rules. They serve as coaches, guiding the team, product owner, and business stakeholders. The Scrum Master's role is that of a facilitator, scheduling resources and resolving impediments, insulating the development team from external disruptions.

 

3. Development Team: Composed of self-organized individuals, the development team is responsible for creating and ensuring the quality of the product. This cross-functional team includes testers, designers, ops engineers, and developers, working collaboratively to deliver valuable outcomes. Additionally, stakeholders may serve as observers or counselors in the Scrum process.

 

Conclusion:

Agile methodologies, especially Scrum, have become an integral part of the daily operations of software development companies. The adoption of agility brings about enhanced quality in software development and management processes. To maximize the value of the final product, organizations must establish well-structured teams that diligently follow the methodology and employ effective strategies. Hybridization of Scrum with other development methodologies is common, as Scrum alone may not cover the entire product development lifecycle. However, it is important to exercise caution to ensure that additional processes complement and enhance the Scrum implementation. While Scrum is well-suited for many projects, geographically dispersed development teams present challenges due to the limited time available for iterative testing. Nevertheless, Scrum continues to reshape the software development landscape, empowering teams to deliver exceptional results.

Supported data types encompass TEXT, INTEGER, and REAL, while other types necessitate conversion to one of these formats before being saved in the database. Android automatically handles SQLite databases, eliminating the need for manual setup or administration.

 

Conclusion:

 

The extensive network coverage and prevalence of mobile phones render them an ideal platform for personal ubiquitous computing. Place Reminder, as evidenced during its two-week deployment, has verified the usefulness of location-based reminders, even with coarse location-sensing capabilities. Location serves as a widely employed cue for contextual information that can be arduous to detect using alternative methods. The convenience and omnipresence of location sensing offered by mobile phones overshadow the present limitations, positioning them as a promising platform for personal ubiquitous computing. The study has also unveiled unforeseen applications of location-aware reminders, such as creating motivational reminders to undertake activities with varying priorities over time. Similar to utilizing post-it notes in visible locations, Place Reminder empowers users to set motivational reminders at various shops.
