Energy Harvesting Aware routing protocol for wireless sensor networks

This paper considers energy efficiency of routing protocols in wireless sensor networks. Many routing protocols for sensor network have been proposed, some of them tried to cope with the ad-hoc nature while some others focus on improving the energy efficiency. We propose an Energy Harvesting Aware Ad hoc On-Demand Distance Vector Routing Protocol (AODV-EHA) that not only inherits the advantage of existing AODV in dealing with WSN´s ad hoc nature, but also make use of the energy harvesting capability of the sensor nodes in the network, which is very meaningful to the data transmission in the environmental and military applications under consideration. Simulations results show the proposed routing protocol has advantages over competing routing protocols in terms of energy cost for data packet delivery.
