In this letter, a node deployment strategy is proposed for blindness avoiding in wireless sensor networks (WSNs) on the basis of ant colony optimization (ACO). Firstly, by group division of nodes, a group-based connection mechanism is designed to avoid blindness of connection and reduce deployment cost. Secondly, by actual load evaluation for a critical region, a load-balancing deployment mechanism is designed to prevent blindness of load-balancing deployment and realize on-demand load balancing in the true sense. Finally, simulations show the effectiveness and superiority of our findings.
