Simulation result reveals that in a 8-hop network consist of 81 Mica2 sensor nodes,the synchronization error of every sensor node varies from 67.70% to 91.58% of that in BTS,except for some resister nodes whose synchronization errors keep unchanged.

• 模拟的结果表明:在由81个Mica2节点组成的8跳网络内；除抗拒节点的同步误差保持不变外；其余节点的同步误差减小至改进前的67.；70%25~91
