Abstract :
This paper considers the problem of relocating a sensor node for increasing the qiality of covarage. We present the notion of free-region of nodes in a sensor network. We investigate properties of free-regions and their characterizations in term of in-free region and out-free region. A centralized algorithm for constructing the free region of sensor node in presented. The algorithm runs in O(n^2) time, where n is the number of sensor nodes in the network.
