Random Variation in Coverage of Sensor Networks
نویسندگان
چکیده
Recently, Wireless Sensor networks become one of the most widely used form of ad-hoc networks that has a countless number of applications in our life. Due to the unreliable communication medium and the failure prone sensors, coverage is an important functional property of a sensor network. Coverage is represented as a function of sensor density, which in turn depends on sensing range and the deployment function. The sensing range and the deployment function have a random nature that can greatly affect sensor coverage. In our study, we subject a densely deployed sensor network to stochastic variations in sensing range and deployment. We capture deployment variations in space dimension by a random deployment pattern and a random noise. We also take into account time dependent random variation in noise and environmental factors. More specifically, we study the effect of randomness resulting in a certain percentage of uncovered area in the network.
