A searching tree-based channel assignment scheme for wireless networks

With the wide application of these technologies in wireless networks such as Multipath transmission, opportunistic routing, Cooperative communication and so on, channel interference and resource contention become more intense, which greatly decrease the network throughput, seriously affect network efficiency[1]. Further, the ripple effect which caused by inappropriate channel switching will result in poor channel utilization and unstable networks. In this paper, based on a searching tree structure, we combine the impact of interference degree with the channel resource allocation, so as to reduce the ripple effect and full use of channel resources. Simulation results show that this mechanism well reduces the channel interference and improves the network throughput.
