The Impact of Sensor Range on the Detection Probability in the Random Deployment of Wireless Sensor Network
نویسنده
چکیده
Sensing is a task of paramount importance for proper functioning of wireless sensor network. The sensing influenced many factor, such as the type and variety of the sensors, the number of sensors deployed, the deployment scheme and the characteristic of the target and the environment. Decreasing the sensing range of sensors results a few detections and the overall communication activity of the network decreases. In this paper present an analytical procedure for the computation of the detection probability in randomly deployed wireless sensor networks, based on the sensing range. This formula is possible to determine the required number of sensors to provide a required detection probability.

Communication security of wireless sensor networks is achieved using cryptographic keys assigned to the nodes. Due to resource constraints in such networks, random key pre-distribution schemes are of high interest. Although in most of these schemes no location information is considered, there are scenarios that location information can be obtained by nodes after their deployment. In this paper,...
