Low power routing and channel allocation method of wireless video sensor networks for Internet of Things (IoT)

We propose a new method of multichannel allocation and routing for wireless mesh networks where each node generates event-driven video sensor data. Battery powered video camera sensors are often connected wirelessly to cover a large area. Such wireless video sensor networks are considered as major applications of Internet of Things (IoT). We analyze the power consumption model for wireless video sensor network. We then propose an algorithm to route the sensor nodes and allocate channels in a way that minimizes the overall power consumption while satisfying the required data transmission. We developed a wireless video sensor network simulator to prove the performance advantage of the proposed algorithm. Simulation results are provided with wireless sensor networks of various sizes.
