Wireless sensor networks and artificial immune system are both self-managed distributed systems. A node scheduling scheme for minimizing energy consumption and avoiding collision for wireless sensor network is proposed using the immune clone algorithm with artificial immunity. The proposed scheme first regards one data transmission at a certain moment as an antigen, and potential routes as antibody, and the power consumption by the node sequence as the fitness, respectively, and then eliminates the disabled nodes using the immune stabilization to reconstruct the network topology structure and builds the vaccine bank to complete the secondary reaction of artificial immunity. The simulation results show that the proposed algorithm can not only avoid the collision among sensor nodes when forwarding data packets, but also solve the global optimization problem of power consumption with high convergence speed.
