Due to the mobile sensor is expensive and moving will consume a lot of energy. We used a small part of mobile sensor and most part of static sensors to meet the demand of k-coverage of three-dimensional network, and we have analysis the ratio of them is 1/(2πk^1/2. To achieve k-coverage, we have received the maximum moving distance for mobile sensor is O(log^1/3 in a network with a size of L . At last, we established a mathematical mobility model for mobile sensors, and converted the sensor redeployment for k-coverage into maximum network flow problem, and proposed a distributed relocation algorithm and verified it through experiment simulation.
