A Multiple-State Based Power Control for Multi-Radio Multi-Channel Wireless Mesh Networks
Multi-Radio Multi-Channel (MRMC) systems are key to power control problems in Wireless Mesh Networks (WMNs). In this paper, the authors present asynchronous multiple-state based power control for MRMC WMNs. First, WMN is represented as a set of disjoint Unified Channel Graphs (UCGs). Second, each Network Interface Card (NIC) or radio assigned to a unique UCG adjusts transmission power using predicted multiple Interaction state Variables (IV) across UCGs. Depending on the size of queue loads and intra- and inter-channel states, each NIC optimizes transmission power locally and asynchronously.
