Solar-Aware Routing in Wireless Sensor Networks

In wireless sensor networks energy is a valuable but not necessary scarce resource. While it is often assumed that nodes in sensor networks are powered by batteries, other energy sources such as solar power may provide unlimited energy resources to a changing subset of the nodes. Since these nodes can receive and transmit packets without consuming battery power, routing via these nodes is appealing. In this paper, we present solar-aware routing, a routing protocol for wireless sensor networks that preferably routes traffic via nodes powered by solar energy. Simulations show that solar-aware routing can provide significant energy savings in many scenarios.
