Power problems pose a major challenge when deploying Wireless Mesh Networks (WMNs) in rural areas and hinder the sustainability of wireless mesh network in such areas. This paper introduces a mechanism for controlling transmission power for efficient video transmission in power-constrained rural areas. The mechanism increases the operational lifetime of WMNs. It ensures that the little power available to the nodes in such areas is optimally used. Simulation studies were used to quantify the performance gains of this mechanism. Simulation is done by considering a classic and power controlled Optimized Link State Routing Protocol (OLSR). The authors consider an OLSRbased Wireless Mesh Network (WMN).
