摘　　要：基于ZigBee无线网络工作模式,对家居系统业务的进行分类,不同业务根据不同安全等级采取不同安全认证,同种业务根据不同情况也进行不同安全认证,增强系统安全性、灵活性;针对每个ZigBee节点孤立响应业务请求导致的发射冲突概率变大问题,对每个ZigBee末端节点进行响应时间顺序排列,在接受客户端业务请求后,各个节点根据接受的命令判断自己发送的时间顺序再定时发送,减小了各个节点接受在接受业务请求后孤立响应而导致的冲突概率,时延问题。基于上述描述采用CC2530进行硬件设计、以C++、安卓进行软件设计、以NS2进行性能分析仿真。The system based on the ZigBee wireless network operating mode,classifying household systemsbusiness,different business take different safety certification according to the different security levels,the samebusiness also take different safety certification according to the different situation to enhance the systemsecurity and flexibility;For each ZigBee node,isolatly responding to business requests make the conflictprobability bigger,responding to each end ZigBee node according to chronological order,each node judgeyour time sequence and the timing to send according to the accept command after accepting the client request.so reduced the conflict probability and time delay problem.compared to accepting business requestsisolatly,Based on the above description,using CC2530to hardware design,software design in c++,android,performance analysis in NS2simulation.
