Abstract
Delay-tolerant Networks (DTN) are wireless networks destined to serve places or functions with minimal or not well-established infrastructure. The DTNs are challenged by an intermittent connectivity between the adjacent nodes, and disconnections may occur due to power outages, technical issues or insufficient architecture. To address the transmitting phenomena of relatively large delays and error rates, an interest-based routing approach, in which different interests and data relay to each node will enhance the DTN capacity. The use of throw-boxes will increase the performance of the networks, and an efficient buffer management policy shall be administered to improve the performance of the network. In this paper, a hybrid buffer management policy is enacted in throw-boxes for increasing the performance and energy efficiency of the network. When the buffer becomes full, data with TTL less than 5 hours will be deleted first, and then the interest type with the most copies diffused or the more popular one in the network with a high hop count will be deleted from the throw-boxes so that the data would flow between nodes and other throw-boxes to reach the destination. Of course, the interest with less popularity can also reach the destination by utilizing this approach. Results show that the buffer management policy improves the performance of challenged networks by increasing the delivery probability, the overhead ratio and the delay are decreased and the average remaining energy has better performance compared to other routing protocols.
Highlights
The growing use of powerful mobile devices, together with the current global, fast-paced development of technology and consumption habits, has raised the users’ expectancies and criteria; people are craving for reliable connectivity while on the move. This has resulted in a networking situation where the mobile industry focuses on overcoming the power, CPU, and memory constraints by proposing more sophisticated and better, heterogeneous devices and wireless networks
With the improvement of the Internet, the mobile ad hoc networks (MANET) have begun to operate by themselves, and most people already maintain those continuously connected to the Internet, forming a dynamic and autonomous topology of a self-configuring network of mobile and portable devices
Because they are linked wirelessly, those devices rely on almost no infrastructure, and because of the capacity of MANETs to be forwarding unrelated traffic constantly, they function as routers
Summary
The growing use of powerful mobile devices, together with the current global, fast-paced development of technology and consumption habits, has raised the users’ expectancies and criteria; people are craving for reliable connectivity while on the move. Our contribution in the paper is to provide options and demonstrate that an efficient hybrid buffer management policy might be implemented in throw-boxes to reduce the congestion and improve the energy efficiency when the throw-boxes get full and new data is arriving. If any data arrives at the throw-box when the same is full, the data which is going to be deleted first is the one that has a popular interest or increased diffusion level and high hop count as it would have already been propagated to many nodes and other throw-boxes This will reduce the congestion and increase the energy efficiency, and new data can be spread through the network while the previous one will have the chances to be stored somewhere else. In this hybrid buffer scheme, data with lower interest will reach the destination node
