EMR-PL: Energy-efficient multipath routing based on link life prediction in ad hoc networks
Anuradha Banerjee, Abu Sufian, Paramartha Dutta · Journal of Information and Optimization Sciences · 2017
In mobile ad-hoc networks, traditional multi-path routing techniques elect multiple good paths based on metrics like hop count, delay, or energy consumption, and are not suitable for multipath scenario, especially when the data transmission is supposed to take place simultaneously through all the selected paths. The present multi-path routing protocol EMR-PL estimates the life of routes depending upon the energy-oriented lifespan and velocity-oriented lifespan of links. Among all the discovered routes, the collection consuming minimum energy and having required lifespan is elected for communication. To the best of authors’ knowledge, the present article is the first one to focus on the single nodemulti-path problem and give solution to it. The data transfer is multi-track that is, all the routes belonging to the selected collection, simultaneously forward data packets. The protocol performance is evaluated in terms of data packet delivery ratio, message cost, average node lifetime, consumed energy and end-to-end delay.
