One major problem in the area of Wireless Sensor Networks (WSNs) is the topology control. Topology control protocols in WSNs construct an optimized network topology structure to satisfy the application requirements, such as network connectivity and coverage. In this paper, we deal with the topology control problem by adjusting the transition radius of the sensor nodes. We produce a cluster-based topology control scheme and propose a new Energy Efficient Topology Control Protocol called EETCP. In this protocol, proper transition radius can be determined using Harmony Search (HS) algorithm. The proposed protocol dynamically adjusts transition radius of nodes (unlike some previous protocols which should select radius values among predefined values). Thus, the proposed protocol has some advantage compared to the previous protocols. EETCP has less average number of neighbors compared to the existing protocols. Also, the energy consumption in EETCP is less than other protocols and the network lifetime will be prolonged. In addition, the network connectivity in EETCP is in the acceptable level. The proposed protocol is simulated and the above advantages are demonstrated by the simulation results.
