Abstract:
Due to limited resources of individual senor nodes, there is usually a trade-off between energy spending forpackets transmissions and the appropriate level of reliability. Since link failures and packet losses are unavoidable, sensornetworks may tolerate a certain level of reliability without significantly affecting packets delivery performance and dataaggregation accuracy in favor of efficient energy consumption. However a certain degree of reliability is needed, especiallywhen hop count increases between source sensor nodes and the base station as a single lost packet may result in loss of alarge amount of aggregated data along longer hops. An effective solution is to trade off between energy and reliability whileimproving packet delivery and minimizing unnecessary packet transmissions in favor of high success reception rates ofrepresentative data packets. Based on this approach, the proposed scheme achieves moderate energy consumption and highpacket delivery ratio. The proposed scheme was experimentally investigated on a testbed of TelosB motes and proven to bemore robust and energy efficient than the current implementation of TinyOS2.x MultihopLQI.
