  • 摘要:Improvements in electronic and computer technologies have tiled the path for explosion of wireless sensor networks (WSN). A fundamental component of resource management in WSN is transmitter power control and an efficient power control technique is essential to support system quality and efficiency. The data transmitted from the sensor nodes is highly susceptible to error in a wireless environment which increases the transmit power. Error control coding (ECC) schemes can improve the system performance and has an impact on energy consumption. Further the adverse impacts caused by radio irregularities and fading increases the energy consumption and thereby reduces the WSN lifetime. To reduce the fading effects in wireless channel, multi-input multi-output (MIMO) scheme is utilised for sensor network. This paper proposes a power control solution considering Multivariate Interpolation Decoding RS (MIDRS) Code in Virtual MIMO (VMIMO) WSN using game theoretic approach. The game is formulated as a utility maximizing distributed power control game while considering the pricing function. VMIMO utilising space time block code (STBC) along with MIDRS code enables to achieve higher energy savings and longer network lifetime by allowing nodes to transmit and receive information jointly. The performance of the proposed power control scheme with MIDRS code for the virtual MIMO wireless sensor network is evaluated in terms of utility, power efficiency, energy consumption and network lifetime.
