Efficient Cooperative Caching in Disruption Tolerant Networks

Problem Definition

Problem Description: One of the major challenges in disruption tolerant networks (DTNs) is the efficient access of data due to low node density, unpredictable node mobility, and lack of global network information. Traditional methods focus on data forwarding, but there is a lack of emphasis on providing data efficiently to mobile users. The delay in data access is a critical issue that needs to be addressed in DTNs. Existing caching techniques may not be sufficient to handle the unique characteristics of DTNs. Nodes may struggle to access data quickly and efficiently due to limited caching locations and coordination among nodes.

This inefficiency can lead to delays in data retrieval, impacting the overall performance of the network. By implementing a cooperative caching approach for efficient data access in DTNs, we can improve the speed and reliability of data retrieval for mobile users. By strategically caching data at network central locations and coordinating multiple caching nodes, we can optimize the tradeoff between data accessibility and caching overhead. This will ultimately enhance the overall performance of DTNs by facilitating faster and more reliable data access for users in challenging network conditions.

Proposed Work

The project titled "Cooperative Caching for Efficient Data Access in Disruption Tolerant Networks" aims to tackle the challenges faced by disruption tolerant networks (DTNs) in providing efficient data access to mobile users. DTNs are characterized by low node density, unpredictable node mobility, and lack of global network information, making data forwarding a primary area of research. This project focuses on reducing data access delays by increasing the number of nodes that can share and coordinate cached data. By intentionally caching data at network central locations selected using a probabilistic selection metric, the project aims to optimize the tradeoff between data accessibility and caching overhead. By coordinating multiple caching nodes, the proposed scheme significantly improves data access performance compared to traditional techniques.

This research falls under the Networking and Wireless Research categories, specifically in the subcategories of Mobile Computing Thesis and Routing Protocols Based Projects. The project utilizes NS2 for simulation and analysis purposes.

The project on "Cooperative Caching for Efficient Data Access in Disruption Tolerant Networks" can be highly beneficial for various industrial sectors facing challenges related to data access in mobile networks. Industries such as logistics, transportation, and remote monitoring can benefit from the proposed solutions in DTNs. In logistics, for example, where vehicles may operate in remote areas with intermittent connectivity, efficient data access is crucial for real-time tracking and delivery optimization. Similarly, in remote monitoring applications such as environmental sensing or infrastructure management, fast and reliable data access is necessary for timely decision-making. The project's proposed solutions, including cooperative caching and strategic data placement, can be applied within different industrial domains to address specific challenges.
