Energy-Efficient Lifetime and Network Performance Improvement for Mobility of Nodes in IoT

Internet of Things (IoT) plays a significant role in the modern world day-to-day activities. Most of the IoT devices used are battery-operated, wherein energy management is most important factor for proper functioning of the application in the network. Mobility of nodes in IoT network is the big challenge with respect to energy consumption, and it degrades IoT network lifetime. In the proposed work, mobility and energy management of IoT nodes are considered to achieve better network performance and to improve the IoT network lifetime. Here, congestion control algorithm detects congestion and mitigates by adjusting the contention window through clear channel assignment (CCA) which increases throughput of the IoT network. The simulation findings suggest that the CCA congestion strategies significantly boost the performance of the network and provide optimal utilization of energy when compared to similar existing methods.
