Relay Placement Based on Divide-and-Conquer

Ravanbakhsh Akhlaghinia, Azadeh Kavianfar, and Mohamad Javad Rostami

Abstract—In this paper, we define a relay placement problem to cover a large number of sensors according to multiple purposes using a minimal number of relays. Finding the best solution requires exponential run time that takes years in large networks. Therefore, we divide the main problem into sub-problems and design a polynomial-time algorithm for finding an approximate solution. We developed a software tool for running the algorithm and graphical representation of placement. Using this tool, our evaluation experiments show the performance of the polynomial-time algorithm in comparison with the best solution.

Index Terms—Wireless sensor network, placement, coverage, clusterhead, relay.
