Simulation of wireless acoustic sensor network localization system using true time

The emergency of wireless sensor network provides a distributed, low cost and flexible solution for acoustic localization system. Location precision is a critical parameter for this system. In this paper, we use True Time, which is a Matlab/Simulink co-simulation block library to establish a simulation environment and establish a relationship between localization precision and PRR (Package Reception Rate). With the PRR decreasing, the AOA precision is get lager. Hence, in a given spatially deployed sensor network location system, the location precision will get larger. Therefore, the PRR should be controlled in a rational level, which is depended on the trade-off between performance and efficiency.
