摘要
通过对无线生理传感器网络TPSN算法的研究,针对采用TPSN算法进行时间同步时产生的同步误差,采用最小二乘法对其进行改进,并在NS-2仿真环境下进行仿真分析。仿真结果表明改进后算法的时间同步误差更小,同步精度更高,更适用于无线生理传感器网络。
Through the research of TPSN algorithm in wireless body sensor networks, aiming at synchronization error caused by time synchronization of TPSN algorithm,the algorithm is improved with least square method, and it is simulated in NS-2 simulation environ- ment. Simulation result shows that synchronization error of improved algorithm is lower, and synchronization accuracy is higher, and it is more suitable for wireless body sensor networks.
