A Fuzzy Based Priority Approach in Mobile Sensor Network Coverage
نویسندگان
چکیده
In this paper a new fuzzy based approach for improving network coverage in wireless mobile sensor networks is proposed. In the proposed approach firstly each mobile sensor node determines its neighbors and its distance from borders and obstacles. According to these values, fuzzy inference engine calculates the priority of node for movement. Then according to the priority, in turn, nodes move away from each other to increase coverage area in the target field. Simulation results show that our fuzzy approach can reach higher degree of coverage against other common approaches like FOA, VEC and TRI algorithms.
