Battery powered video camera sensors are often connected wirelessly to cover a large area. We propose a multi-channel allocation and routing method for wireless mesh networks where each node generates event-driven video sensor data. How the routing and channel allocation is done has large impact on the battery life time of such networks. We realistically analyze the power consumption model based on the utilization of each link. We then present an optimization formula of utilization-aware channel allocation and routing that minimizes the overall power consumption while transferring all the required video data. We developed an efficient heuristic algorithm that accurately approximates the formula. A network simulator has been developed, which show that the proposed method can reduce the overall power consumption.
