摘要
IEEE802.15.4标准是为满足低速率、低能耗、低成本需求而制定的无线个人区域网(LR_WPAN)规范。通过用网络仿真软件NS2对基于IEEE802.15.4的无线传感器网络的主要性能指标进行分析,较为详实地论述了IEEE802.15.4MAC层基于时槽的CSMA/CA机制,最后给出仿真环境及其结果,并进行度量分析和阐述各指标间的依赖关系。
IEEE802.15.4 is a standard to meet the need for low-rate low-cost low-power wireless personal area network.By using the network simulation software NS2,it does the analysis of the main performance indexes of the WSN based on IEEE802.15.4,and details the slotted CSMA/CA machanism in the IEEE802.15.4 MAC protocol.Finally it makes out the simulation environment and its results,and makes metrics anlysis and expounds the interdependency between the indexes.
