Energy Aware Routing Protocol for Heterogeneous Wireless Sensor Networks

In this paper we present Energy Aware Random Asynchronous Wakeup (RAW-E), a novel crosslayer power management and routing protocol for heterogeneous wireless sensor and actor networks. RAW-E is an extension of our previously presented Random Asynchronous Wakeup (RAW), a power saving technique for sensor networks that has been shown to reduce energy consumption without significantly affecting the latency or connectivity of the network. RAW-E is a distributed, randomized algorithm where nodes make local decisions on whether to sleep, or to be active based on the energy level of its neighbors. The primary result of RAW-E is the reduction of energy disparity among sensor nodes. Therefore, while the energy reduction is spread uniformly among nodes, the life of network connectivity is prolonged. RAW-E is scalable to the change in network size, node type, node density and topology. RAW-E accommodates seamlessly such network changes, including the presence of actors in heterogeneous sensor n...
