Multi-Radio Multi-Channel (MRMC) WMNs result in power control problems including interference, un-scalable connectivity and energy consumption. Several previous studies have focused on the single radio wireless configurations while studying power control problems. However, such contributions can not solve the power control problems in MRMC configurations because of the architectural and structural differences amongst them. This paper presents a dynamic power control for MRMC WMNs. First, WMN is represented as a set of disjoint Unified Channel Graphs (UCGs). Second, a new power selection MRMC Unification protocol (PMMUP) is proposed that coordinates interactions among radios assigned to a unique UCG. Third, each radio-pair adjusts transmission power using the predicted Interaction State Variables (IVs) across UCGs. To ensure convergence, IVs are derived from the dynamic linear quadratic controller. Depending on the size of the queue loads and intra-and inter-channel states, each radio optimizes the transmission power locally and asynchronously. The efficacy of the proposed method is investigated through simulations. |
