Abstract
Wireless Body Area Network (WBAN) is a promising cost-effective technology for the privacy confined military applications and healthcare applications like remote health monitoring, telemedicine, and e-health services. The use of a Software-Defined Network (SDN) approach improves the control and management processes of the complex structured WBANs and also provides higher flexibility and dynamic network structure. To seamless routing performance in SDN-based WBAN, the energy-efficiency problems must be tackled effectively. The main contribution of this paper is to develop a novel Energy Optimized Congestion Control based on Temperature Aware Routing Algorithm (EOCC-TARA) using Enhanced Multi-objective Spider Monkey Optimization (EMSMO) for SDN-based WBAN. This algorithm overcomes the vital challenges, namely energy-efficiency, congestion-free communication, and reducing adverse thermal effects in WBAN routing. First, the proposed EOCC-TARA routing algorithm considers the effects of temperature due to the thermal dissipation of sensor nodes and formulates a strategy to adaptively select the forwarding nodes based on temperature and energy. Then the congestion avoidance concept is added with the energy-efficiency, link reliability, and path loss for modeling the cost function based on which the EMSMO provides the optimal routing. Simulations were performed, and the evaluation results showed that the proposed EOCC-TARA routing algorithm has superior performance than the traditional routing approaches in terms of energy consumption, network lifetime, throughput, temperature control, congestion overhead, delay, and successful transmission rate.

Summary
The recent advancements in information and communication technology have led to the modernization of the applied sciences. This paper focuses on avoiding these hot-spot nodes by preventing the heated node from the transmission process until the temperature is reduced to attain safe transmission Another vital factor considered in this paper is the congestion in routing paths, mainly due to the overburden of data in the selected shortest routes [13]. The three vital problems of energy consumption, temperature, and congestion in SDN-based WBANs must be handled effectively to achieve superior routing, which is very important in healthcare and military applications. The temperature control is implemented at the forwarding nodes’ selection stage based on the current temperature of nodes and the temperature rise in the underlying tissues By considering these approaches, efficient routing is achieved in the SDN-based WBAN and it helps in stabilizing the applications developed using it.
