In this paper, a new energy efficient LEACH-based protocol for wireless sensor network is presented. The main goal of this protocol is to increase the network lifetime. Sensor networks are usually spread out in a large field and changing node batteries are not easily done. This protocol takes the advantage of sub-threshold technique and bee colony algorithm in order to optimize the energy consumption of a WSN network. Simulation results show that the energy consumption of the wireless sensor network reduces by 25 percent using STBCP in comparison with recent LEACH-based protocols. It is has been shown that the average energy of the network remains balanced. In addition, the lifetime of a network using STBCP protocol increases by 23 percent.
