Remaining-energy based routing protocol for wireless sensor network

Energy consumption in sensor network is one of the most important goals in designing a routing protocol. An energy efficient routing protocol will decrease number of transmitted and received packets, because main consumption part in routing is using antennas and signals. This paper presents an energy efficient routing protocol, called Remaining-Energy Based Routing (REB-R). The idea behind REB-R is broadcasting remaining energy along with data in the data packet instead of calculating a parameter, related to remaining energy and broadcasting it. REB-R is compared to two well-known protocols, AODV and TANT. Simulation is done by NS-2 framework. In order to compare REB-R with both of them, T-ANT has been implemented inside NS-2 and AODV implementation is changed to support energy consumption. For 200 nodes in area, REB-R uses less than 50% of energy consumption of the other protocols. Number of saved nodes for T-ANT and AODV is less than 20% but REB-R saves all of nodes during simulation time.
