Abstract:The reasonable deployment of sensor nodes while guaranteeing the secure connection is one of the most important challenges in designing wireless sensor network. Traditional algorithms merely aim at network coverage rate, which leads to the reduction of the secure connectivity degree. In this paper, the model of sensor nodes deployment is theoretically analyzed. Combined with rapid multi-objective optimization of the capacity of elitism non-dominated sorting genetic algorithm, an optimal sensor deployment algorithm based on secure connection is proposed, to guarantee the effect of network tracking and secure communication. The performance of algorithms under different deployment model is analyzed. Simulation results demonstrate that the novel algorithm proposed in this paper can implement network coverage rate and secure connection degree more rapidly and efficiently and hence meets the actual demand in wireless sensor network.
