Cooperative sensor networks with bandwidth constraints

Abstract

A Cooperative Sensor Network is an array of sensors interconnected by a local or wide area tactical communications network. Sensor data is shared between the sensors and used as input to an estimator to measure a process such as target location or target identification. In this paper a stochastic sensor scheduling framework is applied to the position estimation of multiple emitter targets using a Cooperative Sensor Network where the communications bandwidth between sensor nodes has been constrained. The stochastic sensor scheduling problem is presented and a practical sub-optimal sensor scheduling algorithm for multi-target localisation using bearing-only sensors is demonstrated in simulatio..
