Advancements in Internet of Things (IoT), have gained much popularity and significant usage in real time applications as it communicates with physical devices or objects through exchanging digital data. IoT transforms the physical world object into meaningful digital information that is available from anywhere at any time. IoT has influenced human life and has become an integral part of our life. IoT explores its wide range of application fields in surveillance systems, military, smart cities and intelligent transportation system (ITS). IoT device is equipped with smart autonomous sensor (nodes) that can intelligently sense physical environment, collect data, process and deliver the digital data to paired devices. Nodes are battery operated and are resource constrained, with limited battery, computation power, energy, bandwidth, storage, and communication range. Connectivity and energy efficient routing among devices becomes more complex as the number of devices is increased. Integration of WSN and IoT offers a game changing solution to guarantee network lifetime and better connectivity for nodes equipped with irreplaceable battery which poses a challenging issue in extending network lifetime. Nodes consumes energy during data transmission and reception, while traditional routing scheme mainly concentrates on utilization of shortest path from source to destination ignoring energy efficient path. Cluster based routing scheme provides energy efficient routes and optimizes energy consumption of nodes and plays a vital role in extending network lifetime. Low energy adaptive clustering hierarchy (LEACH), a well-known clustering technique mainly concentrates on single hop communication and random selection of the cluster head (CH), and is unable to sufficiently balance energy dissipation. Nodes closer to BS consumes more energy and have excessive transmission overhead resulting in hotspot or energy holes problem. To overcome these issues, we propose an energy efficient cluster-based routing scheme for WSN assisted IoT known as EECBR. EECBR considers modification of existing LEACH to improved LEACH by considering energy parameters such as residual energy, average network energy, total network energy and new threshold value during CH selection. The rotation of CH aids to balance nodes energy and extends network lifetime. Nodes near to BS other than CH do not participate in cluster formation to avoid hotspot problem and balances nodes energy.
