Hybrid Energy-Efficient Protocol in Delay Tolerant Networks for IoT Systems
Amr Elsaadany, Mohamed A. Aboulhassan · 2019
The wide spreading of IoT applications requires the development or modification of networking protocols in order to ensure messages delivery and alleviate problems such as intermittent connections. While these new applications differ in their delivery requirements, existing protocols do not realize the variation in message delivery requirements or the nature of the message to be delivered. This on top of the fact that the sending nodes have limited energy for the sensing and sending of the messages. In this paper, we propose a new routing protocol that addresses the message delivery probability under constrained energy source and how the application of this protocol can improve the performance of delay tolerant networks. The results of our network model demonstrate the improvements in the nodes' energy level while effectively reducing the overhead that existed due to high number of unnecessary messages copies.
