Optimization of adaptive linear sensor node array in Wireless Sensor Network

This paper presents a method of optimizing sensor node coordination in order to reassign the nodes in linear array arrangement to form a linear antenna array. This linear sensor node array (LSNA) is constructed within random sensor node deployment. The LSNA should be optimized as closely comparable as a conventional uniform linear array (ULA) to minimize the beamforming performance errors. Beamforming has been introduced in wireless sensor networks (WSNs) in order to increase the transmission range of individual sensor nodes. The performance of the two methods: LSNA and ULA are compared in adaptive manner. The results of the constructed adaptive LSNA demonstrated an excellent agreement compared to the conventional ULA.
