Abstract:

According to the characteristics of WSN nodes vulnerable to failure and damage, the invulnerability of WSN network was studied from the perspective of topology structure. Taking the natural connectivity of the network as the optimization objective, and considering the constraints of the total connectivity of the network nodes, the number of nodes and links, the communication radius of the nodes and the load of the nodes, a network topology invulnerability optimization model was established. Model was NP-hard problem, this paper proposed a new heuristic algorithm-adaptive simulated annealing particle swarm optimization algorithm, which applied the simulated annealing method before updating the particle population, to replace the part of fitness poor particles, overcome the traditional particle swarm optimization algorithm easy to fall into local optimum, and the inertia weight adaptation method was used to guarantee the convergence speed. Experimental results show that this method is effective to solve the network topology invulnerability optimization model. By using different strategies to attack the network nodes, the network topology optimized by the proposed algorithm is proved to be highly invulnerability.
