基于无线传感器网络的混合MAC协议
Hvbrid MAC Protocol Based on Wireless Sensor Network
摘要
Abstract
This paper proposes a hybrid Medium Access Control(MAC) protocol based on Wireless Sensor Network(WSN) by combining with the work pattern of Time Division Multiple Access(TDMA) and Carrier Sense Multiple Access(CSMA). It Introduces Fast Collision Resolution(FCR) into MAC protocol. Sensor-MAC(SMAC) protocol is unproved in the mode of CSMA. Under such condition, the contention window changes according to the changes of network traffic. The hybrid MAC protocol can switch the working way self-adaptively and smoothly between the mode of CSMA and TDMA. Simulation results on OMNet++ show that the improved protocol can enhance the utilization efficiency of channel and prolong lifecycle of network.关键词
