Dynamic target detection

Abstract In this chapter, the design and configuration of a wireless sensor network for target detection is studied. Subject to a budget limit for sensor nodes, the network is required to secure a certain detection probability and to work for a reasonable time. One model of randomly distributed network is presented to fulfill this requirement. A state switching scheme is developed for sensor nodes to save energy. The functional relationships between detection probability and related parameters of sensor nodes, network and target are analyzed. Moreover, a two-level optimization problem is formulated. At the lower level, we optimize the behavior of each sensor node subject to its energy constraint, and at the upper level, we maximize the network lifetime. An equilibrium solution of the two-level optimization problem is obtained by a numerical method. An application example is presented to illustrate the main results.
