UMRC: Multichannel and multihop clustering communication for improving performance of Wireless Sensor Networks

The ability of newer generation of commercially available radios used on the sensor nodes operating on different channels (called multi-channel) provides an opportunity to alleviate the effects of interference and consequently improve network performance significantly. In this paper, we investigate a multichannel communication algorithm associated with routing process (called UMRC - mUltichannel and Multihop clusteRing Communication scheme) for Wireless Sensor Networks (WSN) in order to improve the capacity and network performance with the following features: interference and contention-free, multi-path routing, energy efficiency and load balance. We use simulation technique to evaluate and compare the performance of our new algorithm to other similar single channel schemes in terms of energy consumption, traffic load balance, number of aliving node and network throughput. The simulation results show that the proposed multi-channel scheme can increase the performance significantly compared to other proposed schemes.
