ADAPTIVE PSO- BASED POWER SCHEDULING ALGORITHM IN WIRELESS MESH NETWORK

Abstract

We introduce an adaptive PSO-based scheduling algorithm to maximize network throughput in wireless mesh networks through adaptive power and rate control. By configuring the modulation/coding scheme of wireless communication at the highest feasible power and rate levels, the algorithm allows transmitters of unscheduled links to calculate the maximum potential Signal-to-Interference and Noise Ratio level at which their links could operate if scheduled next. This process is repeated until the power margins of scheduled links cannot accommodate more additions to the scheduled time slot. Our proposed work focuses on an Adaptive PSO-based power scheduling algorithm for maintaining power margins in different wireless channels in OFDM and CDMA channels.
