Abstract

Coverage rate is an important parameter in WSNs, which the higher the coverage rate, the better the ability of the network to fulfill its monitoring function. Aiming at the shortcoming of the great error in the calculation for network coverage rate, we propose an algorithm for calculating coverage rate based on geometry decomposition approach (CRGD), a kind of accurate calculating method. Against the random WSNs in non-border area, it segments the irregular coverage region into several regular bows and triangles by geometry decomposition approach, which areas can be calculated conveniently. Then, it accumulates the areas and gets the coverage rate finally. According to the experimental results and analysis, CRGD’s precision can be over 99%, which make the algorithm meet the requirements of practical application satisfactorily. . .
