| Abstract | In this work we consider the important problem of energy balanced data dissemination in wireless sensor networks (WSN), where data are generated by the sensors and must be routed toward a unique sink. Sensors route data by either sending the data directly to the sink or in a multi-hop fashion by delivering the data to a neighboring sensor.We decompose the transmission range of sensors into concentric circular bands rings based on a minimum transmission distance between any pair of sensors. We also propose a data dissemination protocol that exploits the above-mentioned decomposition to meet the specific requirements of a sensing application in terms of trade-off between energy and source-to-sink delay. We prove that the use of sensors nodes, which lie on or closely to the shortest path between a source and a sink, as proxy forwarders in data dissemination from sources to a sink, helps simultaneously balance energy consumption and delay. Furthermore, this protocol is based on stochastic estimation methods and is adaptive to environmental changes |
