THE MULTICHANNEL PD -CSMA WITH 3 -WAY HANDSHAKE BASED ON CONFLICT RESOLUTION ALGORITHM IN WSN

Article History: Average cycle method is used to analyze the multichannel PD -CSMA with 3-way Handshake based on binary tree conflict resolution algorithm in WSN, getting the critical mathematical expressions of the system throughput, each priority traffic throughput, etc. The computer simulation results verify the correctness of the theory and show that the novel protocol has better performances than the anterior ones'. Compared with the multichannel PD-CSMA with 3-way handshake in WSN but without conflict resolution algorithm, the new protocol's throughput is greatly improved. On the basis of allocating the channel resource fairly, much of the resource is distributed to higher priority , realizing the better quality of service.
