摘 要：This paper studies the problem of determining sensor locations in a large sensor network using only relative distance（range） *** this paper,we consider a synchronous communication protocol when 1) the communication delay between sensors is uncertain;2) successive packet loss is *** on the barycentric coordinate representation,our work generalizes the DILOC algorithm in the communication environment with time delays and packet ***,a synchronous communication protocol is developed,and the distributed localization algorithm is mathematically modeled as a linear difference equation with time-varying communication ***,the time-varying-delay model is proved to be globally convergent to the true coordinates under consensus framework with quotient graphic ***,simulation examples are provided to demonstrate the effectiveness of the theoretical result.
