Abstract
Background & Objective:
In this paper, a new energy efficient LEACH-based protocol
for wireless sensor network is presented. One of the main issues in Wireless Sensor Networks
(WSNs) is the battery consumption. In fact, changing batteries is a time consuming task and expensive.
It is even impossible in many remote WSNs.
Methods:
The main goal of the presented protocol is to decrease the energy consumption of each
node and increase the network lifetime. Lower power consumption results in longer battery lifetime.
This protocol takes the advantage of sub-threshold technique and bee colony algorithm in order to
optimize the energy consumption of a WSN. Simulation results show that the energy consumption of
the wireless sensor network reduces by 25 percent using STBCP in comparison with recent LEACHbased
protocols. It has been shown that the average energy of the network remains balanced and the
distribution of residual energy in each round is equitable.
Conclusion:
In addition, the lifetime of a network using STBCP protocol has been increased by 23
percent regarding recently presented routing protocols.
