The Internet-in-Things (IoT) is a network infrastructure containing large number of uniquely identifiable things or objects that are interconnected through the internet. These day to day physical objects are also connected to the sensors, for receiving the information from objects. This structure allows them to communicate with each other without any human interaction, thus forming a heterogeneous WSN. This IoT network depends on the wireless sensors; a massive amount of data is collected by the sensors and communicated to specified locations over the network. The lifetime of the network and communication process is purely based on the energy sources of the objects and applications. Energy consumption is one of the major issue in WSN based IoT applications.The researchers and developers have always regarded this issue as a challenge for WSN based IoT environment. The IoT sensors continuously require energy to receive and communicate to remote locations of the IoT network, but the main resource of power is the battery.Efficient Energy Harvesting techniques could remove the needs of frequent energy source replacement, thus offering a near perpetual network operating environment. Thus, energy harvesting is the best solution to retain the lifetime of the sensors and the network. In this paper, our primary focus is to study energy harvesting performance in WSN based IOT applications, in order to increase the availability of the sensors and retain the lifetime of the network. We also discuss a new routing algorithm EHARA, which has been further enhanced by integrating a new parameter called ‘extra backoff’. This algorithm improves the lifetime of sensor nodes as well as the quality-of-service (QoS) under variable traffic load and energy availability conditions.
