ZigBee network is popular ad hoc wireless sensor network (WSN) with low-power consumption, low cost, low complexity. But in fact as low localization accuracy, the ZigBee localization scheme is not large-scale use. In order to satisfy the demand for a large number of location-based applications, we add the interrupt module into the ZStack 2007 communication protocol, which improves the real-time processing capabilities, and reduce the power consumption of overall system. Meanwhile, this paper proposes reliability weighted TOA localization algorithm to mitigate the interference, and improve the positioning accuracy. Experiments and simulations show that this localization solution has a great advantage than the traditional solution.
