Optimal and Approximate Approaches for Deployment of Heterogonous Sensing Devices

In this paper, a modeling framework for the problem of deploying a set of heterogeneous sensors in a field with time-varying differential surveillance requirements is presented. The problem is formulated as a mixed integer mathematical program with the objective is to maximize coverage of a given field. Two meta-heuristics are also used to solve this problem. The first heuristic adopts a Genetic Algorithm (GA) approach while the second heuristic implements a Simulated Annealing (SA) algorithm. A set of experiments are used to illustrate capabilities of the developed models and to compare their performance. The experiments investigate the effect of parameters related to the size of the sensor deployment problem including number of deployed sensors, size of the monitored field and length of the monitoring horizon. They also examine several endogenous parameters of the developed GA and SA algorithms.
