초록/요약

Sensor networks are resource constrained in terms of battery and other physical resources. Conserving energy is one of the major goals in designing the sensor networks. Studies show that communication costs is one of the major burden on the energy budget of devices comprising the sensor networks. Thus reducing communication overhead would be of great significance in reducing overall energy consumption. Routing protocols determine the routes taken by data in the network, and thus play a key role in determining how energy is utilized in network. In this work we present a new routing protocol, which does not employ any route setup and still performs at a level close to that of traditional routing protocols. It accomplishes this by selecting the next hop node, based on their addresses, which are pre assigned in such a way that they represent the position of the node in the logical network. We analyze the results of our experiments on testbed and discuss the usefulness of the protocol.
