Present research work on the Internet of Things and Fog computing has taken hype due to the low cost of building them by optimized sensors. Wireless sensor devices play a vital role in developing IoT sensing infrastructure. These devices are connected to form a network known as the WSN assisted IoT network. The number of things is verdant in IoT creates an immense energy need. So, efficient energy utilization is required to alter the green IoT environment. These sensor devices are having limited power and computational capabilities. We can use energy-efficient data routing protocols as data transferring with these low powered sensors is very challenging. One may use the sensors for more time in sensing the environment and sending the information. This proposed protocol deals with a reliable routing protocol for IoT sensing Infrastructure. Initially, a rendezvous region was created in the middle of the network area. Clustering and multipath technique are used because it reduces energy consumption and increases reliability. The proposed protocol is simulated within Castalia simulator for attaining the performance beneath different characteristics like packet delivery ratio, the average energy consumption, end to end delay, and network lifetime. It is observed that the suggested technique is useful in energy consumption and helps in boosting the IoT infrastructure network lifetime.INDEX TERMS Internet of Things, hot spot problem, WSN-assisted IoT, routing protocol, green IoT.
