Recent advances in wireless communication and technologies have given rise to low-cost sensor networks. Sensor networks comprise of low-cost, low-power nodes that are densely deployed in the environment to monitor a specific state of the environment, for example: temperature, light, sound, speed or radiation. This paper presents a new data forwarding algorithm for sensor networks that takes into consideration the direction of the message, the positional relevance of a node to the message and the available power at that node. We conclude this paper by discussing an experimental study of the performance of the proposed data forwarding protocol for sensor networks.
