Abstract: This paper presents the coverage and connectivity problems of wireless sensor networks (WSN), explains the coverage problems of WSNs in detail, outlines the issues of WSN coverage requiring urgent solution, and gives a controlled greedy sleep (CGS) algorithm based on �K�-coverage. By adopting WSN coverage mode with different sensing radius and utilizing the mended �K�-NC CGS algorithm, it gains the network coverage rate which is more in line with the practical application and lifetime.
Key words: communication technology; K-coverage; CGS algorithm; K-NC CGS algorithm; coverage rate; lifetime
