并行调度两级轮询控制传感器网络 MAC 协议分析
Study on parallel two-level polling cont rol based MAC protocol for Wireless sensor networks
摘要
Abstract
Aiming at the delay-sensitive applications with an unbalanced property of network flow , a new protocol called the parallel two-level polling control based MAC ( PTLP-MAC) is proposed in this paper .The PTLP-MAC provides priority distinction from the aspects of the polling route and service scheme assignment .By proceeding with the data transmission and request parallel , the mean waiting time of the data packet is further reduced. Further-more, by use of the embedded Markov chain and the theory of probability generating function , the mathematical functions were established and closed form expressions were given for obtaining the mean cyclic period , as well as the mean queue length and the mean waiting time characteristics .The analytical results were also verified through extensive computer simulations .关键词
