Coordinated throughput optimization for mobile sensor networks under heterogeneous fading conditions

Abstract

This paper considers the P2P throughput optimization of mobile wireless sensor networks under a Rician/Rayleigh heterogeneous fading environment. The Rician/Rayleigh fading scenarios considers both extreme cases of signal propagation, that is, dominant line of sight (LOS) signal and No LOS (NLOS) signal.We focus on a type of P2P communication between wireless sensor nodes where the desired signal experiences Rician fading channel and the interfering signals undergoes Rayleigh fading channel. The coordinated link quality-and position-aware route (C-LPAR) reconfiguration strategy is proposed to exploit the multipath fading characteristics and mobility of nodes in order to provide optimal end-to-end throughput routes in presence of path loss, fading and interference. We studied the performance of proposed strategy under different environmental conditions and investigated the achievable throughput as well as number of hops and euclidean distance of the routes.
