Power consumption optimization based on B-MAC protocol for multi-scenario WSN by Taguchi method

Abstract

Wireless sensor network (WSN) is exploited in diverse applications. Further, the variety of WSN applications it let the door open for researchers to deal with WSN challenges. However, the critical issue faced WSN is the prolong lifetime of sensor nodes. Additionally, the topology of a wireless sensor network often changes frequently due to node failure, damage, addition, movement, and energy depletion which effect change in the network topology lead to a multi-scenario network. This paper aimed to study the effect of multi-scenario on the MAC protocol WSN for energy efficiency. The proposed method is based on Taguchi method. Further, Berkeley-MAC (B-MAC) protocol parameters are optimized for different WSN scenarios. Moreover, simulation experiments are carried out by OMNET++ to prove the work in this paper. The obtained results show that Taguchi B-MAC optimizing reduces the power consumption of WSN for a multi-scenario network.
