Abstract
In these recent years, loT has graded the forecast of agriculture and automation. A loT, which mostly comprises different technologies. The wireless sensor network is one such big technology. Nodes communicate with each other through the nodes, which are spatially arranged. The communication between nodes is wireless, and the data is sent to the Base Station. Communication is established between the nodes through the concept of routing protocols. We have different routing algorithms for different networks. LEACH, DEEC and more are the routing protocols used for homogenous networks, and SEP (stable election protocol) is one of the routing algorithms used in heterogeneous networks. The importance of these protocols comes from not only the communication but also the need to be energy efficient and less power consumptive. We implemented the routing algorithm SEP to observe its constituents like power consumption, energy usage, data transmission, and the number of dead nodes. By observing the factors of SEP, as it is not much effective protocol and thus implemented the improved or advanced protocol of SEP that is Improved version-SEP. I-SEP is an algorithm for the Stable Election Protocol, which is an improved algorithm. In this improved version of SEP, we have the concept of cluster head formation. It means the group of nodes elects the single node as head and transfers their data to the head. It's the most efficient use of energy as the nodes need not waste energy in transmitting the information as the transmission is the duty of Cluster Heads. In the I-SEP protocol, the number of not live nodes decreases as it is less powerconsumptive. So, its use over the SEP is more helpful in the longevity of nodes and networks. We need to implement the protocol for the purpose of the high network lifetime and the best use of its energy. Implementation was done in MATLAB. We studied the existing algorithm SEP, and after finding the difficulties and drawbacks in the factors, we implemented ISEP.
