Analysis and Performance Evaluation of the IEEE 802.15.4 MAC Protocol
摘要
Abstract
For the problem of how to improve the network transmission performance in wireless sensor networks, the paper proposes a scheme of using different transmission modes for different network topology structures. Based on the analysis of two different network structures: the "tree" structure and the "network" structure by the NS2 network simulation software, the delivery rate(packet loss rate), the average end-to-end delay and the routing overhead are analysed for the two different network structures, and for the beaconless and beacon-enabled operations. The experimental results show that the different network topology structures targeted by different transmission ways really can increase the transmission performance.关键词
