Topology control protocols try to decrease the average of node’s transition radius without decreasing network connectivity. In this paper, we propose a new Particle Swarm Optimization-based Topology Control protocol for wireless sensor networks called PSOTC. In this protocol, proper transition radius can be determined using Particle Swarm Optimization (PSO) algorithm. The proposed protocol dynamically adjusts transition radius of nodes (unlike previous protocols which should select radius values from among predefined values). Thus, the proposed protocol has some advantages compared to the previous protocols. PSOTC protocol has less average number of neighbors compared to the existing protocols. Also, the energy consumption in our protocol is less than other protocols and the network lifetime will be prolonged. In addition, the network connectivity in our protocol is in the acceptable level. The proposed protocol is simulated and the above advantages are demonstrated by the simulation results.
