Modeling the Critical Transmitting Range for Connectivity inWireless Sensor Networks
The research in wireless sensor networks (WSNs) has attracted a lot of attention in recent years. Sensor nodes are often placed in a hostile or dangerous environment where they are not physically protected. Hence, sensor nodes must self-organizationally form a connected network. Additionally, Energy is a decisive resource in WSNs. So the trade-off between connectivity and power control becomes a critical problem in WSNs. In this paper we present nearest neighbor nodes of the two-dimensional WSNs with Poisson point process, which enables each node to find the 1st (respectively, 2nd and Kth) nearest neighbor node and adjust transmitting range according to local requirement, thereby it would contribute to the lifetime of overall network. And then we derive the analytic expression of 1-connected (respectively, 2-connected and K-connected) network. Finally, we present the simulation results and discuss practical value for researchers in this domain.
