Relay characteristic impact on energy consumption in heterogeneous sensor network
چکیده انگلیسی

Indoor heterogeneous wireless sensor networks are considered in this paper. We analyze the power consumption for multihop communications with non-regenerative relays. Since sensor nodes are battery operated, energy consumption is a crucial issue. We determine the optimal relay gains and transmitted power that minimize the dissipated power for a given quality of service in a narrow band fading channel. Our work includes two main contributions: firstly, we study the energy consumption taking into account hardware aspects, especially the relays’ efficiency. In an AWGN channel, carefully analyzing the energy gain as a function of the position, we show that relay characteristics have an important impact on the multihop link consumption budget. We then use a Rice channel model based on simulations and further study the hardware impact on energy saving.
