MAC Protocol Analysis Based on Adaptive Wireless Sensor Network

摘要

High performance communication of wireless sensor network requires MAC protocol to have QoS guarantee function to meet the real-time and reliability requirements of data transmission. The protocol adaptively adjusts the number of sites access and the arrival rate of information grouping to meet the requirements of video voice services such as average waiting time, average site length and throughput. Simulation results show that the protocol model does not change IEEE802.11 standard channel access, without any additional communication overhead, improves both network throughput performance and QoS functionality.
