Evaluation of Hotspot Performance in IoT Enabled Wireless Sensor Network using Special Intermediate Nodes in the Network

Wireless Sensor Network (WSN) equipped with Internet of Things (IoT) technology has been used in many aspects ranging from long-distance data transmission to healthcare, smart city and home automation applications. As part of WSN, a Hotspot node provides vital link between IoTs in heterogeneous networks and other remote networks. Hotspot nodes are used to bridge the gap between communication networks, providing an IPv4 address and establishing point-to-point (or multipoint-to-point) connectivity between the various IoTs and/or remote networks. In this paper, we discuss the performance of Hotspot nodes failure, recovery and its impact on the system performance. The impact of Hotspot redundancy and load balancing on system performance is also discussed. Finally, based on the results, the authors suggests various techniques and methods for improving the performance of Hotspot nodes.
