DEPLOYMENT STRATEGIES FOR COURAGE IN SENSOR NETWORKS

A basic concern in the deployment of a sensor network is the quality of coverage of the area being monitored.  The definition of converage depends on the use of the network, but usually is either the area covered by the sensors or the ability to detect moving objects.  coverage is affected by the capabilities of the sensors, the environment in which they are deployed, their locations within that environment, and their interactions with each other.  Deployment strategies are designed to meet optimization criteria in coverage and cost of deployment under various constraints.  This survey reviews the common sensor models, coverage measures, techniques for evaluating coverage, and deployment strategies found in the literature. While many works address additional issues in deployment such as network connectivity and lifetime, this survey focuses exclusively on issues of coverage.
