On Periodic Node Deployment in Wireless Sensor Networks: A Statistical Analysis

Provided by: University of Western Macedonia Topic: Mobility Date Added: Aug 2011 Format: PDF
Rapid progress made in the field of sensor technology, wireless communication, and computer networks in recent past, led to the development of wireless ad-hoc sensor networks, consisting of small, low-cost sensors, which can monitor wide and remote areas with precision and liveliness unseen to the date without the intervention of a human operator. This paper comes up with a stochastic model for periodic sensor-deployment (in face of their limited amount of battery-life) to maintain a minimal node-connectivity in wireless sensor networks. The node deployment cannot be modeled by using results from conventional continuous birth-death process, since new nodes are added to the network in bursts, i.e. the birth process is not continuous in practical situations.
