针对无线传感器网络信道特性和网络布置等具体问题,以Mica2节点为例,从理论上分析了重发次数、时间窗长度、节点通信半径范围内的节点数量等参数的选取对数据可靠性、节点平均寿命等性能的影响。
This paper took Mica2 node as an example and investigated retransmission' s application in theoretic way. And also considered the network' s parameters' selection here. And the parameters include time slice' s length and the average number of nodes within one node' s retransmission radio, etc. As the result suggests, a longer time slice and less nodes within one node' s retransmission radio brings a more desired effect.
