Energy-Aware Healthcare System for Wireless Body Region Networks in IoT Environment Using the Whale Optimization Algorithm

Wireless Sensor Network (WSN) is one of the most significant technologies that typically involves of a large number of wireless sensor nodes with sensing, communications and computation capabilities. The sustained operation of WSN is achieved through the efficient consumption of node energy. The WSN is used to many applications especially military, science and medical. The WSN performance may be affect some issues such as load balancing, security and reduce energy consumption of the nodes. These issues must be reduced to enhance performance of the WSN structure in different applications. Henceforth, in this paper, Hybrid Emperor Penguin Optimization (EPO) is developed to solve load balancing, security enhancement and reduce energy consumption in WSN. The hybrid EPO is combined with Atom Search Optimization (ASO) algorithm, it is used to improve the updating function of the EPO algorithm. Three major objective functions can be considered towards improve the performance of WSN like load balancing, security enhancement in addition energy consumption reduction. The load balancing can be achieved by optimal clustering scheme which attained applying proposed hybrid EPO. The security also enhanced in WSN with the help of hybrid EPO by computing security measures. Similarly, energy consumption of WSN is achieved optimal routing scheme by hybrid EPO algorithm. The proposed methodology is developed to manage three objectives which is a major advantage. The projected technique can be implemented by NS2 simulator for validation process. The projected technology is contrasted with the conventional methods such as EPO and ASO respectively. The projected technique is evaluated in terms of delivery ratio, network lifetime, overhead, energy consumption, throughput, drop and delay.
