Abstract :
Node localization of the network is the basis for the applications of wireless sensor network, therefore in the wireless sensor network´s each research direction, and the node localization had already become a very important research direction. The beginning chapters of this thesis introduce the knowledge of wireless sensor network and genetic algorithms. The Chapter of this thesis proposes a genetic algorithm based node localization algorithm of wireless sensor network. Firstly, the algorithm gives the encoding method of node. Then through the relations between the unknown nodes and datum node´s correspondence restraint, the optimizing function taking the unknown node position as the parameter is established and the fitness function is designed. And then the corresponding crossover and mutation operators and a algorithm preventing premature are presented. Finally, the efficiency of the algorithm is validated through the simulation.
