Abstract
Combining wireless sensor network and array signal processing technology, a novel array-forming wireless sensor network framework is presented. Sensor nodes, connected through wireless communication, are grouped to form virtual arrays. Then high-accuracy target positioning can be performed with the help of array signal processing algorithms. Considering real-time target monitoring applications, system performance is modeled in aspects of accuracy, delay and power consumption. To satisfy system performance requirements with inherent contradiction among them, system objective function is built and optimized scheduling is obtained with optimization algorithm. Simulation results verified our performance model and the feasibility of array-forming wireless sensor network framework, and also provide suboptimal solutions for scheduling.
