Range Based Power Control for Multi-Radio Multi-Channel Wireless Mesh Networks

Free registration required

Executive Summary

Multi-Radio Multi-Channel (MRMC) systems are key to power control problems in WMNs. In this paper, the authors present a range based dynamic power control for MRMC WMNs. First, WMN is represented as a set of disjoint Unified Channel Graphs (UCGs). Second, each radio assigned to a unique UCG adjusts the transmission power locally using predicted connectivity ranges with other nodes. A new power selection MRMC unification protocol (PMMUP) is proposed that coordinates local power optimizations at the radios of a node. The efficiency of the proposed method is investigated through simulations.
