Analysis of the Wireless Sensor Networks efficient coverage

Coverage is one of the fundamental problems of Wireless Sensor Networks (WSNs). Analyzing the coverage problem of WSN, this paper proposes the concepts of degree of coverage and net coverage efficient ratio. It is theoretically proved through math modeling, theoretical analysis and formula deducting that how much the maximum of efficient coverage area and the maximum of net coverage efficient ratio if full and seamless coverage is met in the square meshes, hexagonal meshes and honeycomb meshes WSN.
