A Modified E-LEACH Routing Protocol for Improving the Lifetime of a Wireless Sensor Network

This paper proposes a modified endtoend secure low energy adaptive clustering hierarchy (MELEACH) algorithm for enhancing the lifetime of a wireless sensor network (WSN). Energy limitations are a major constraint in WSNs, hence every activity in a WSN must efficiently utilize energy. Several protocols have beenintroduced to modulate the way a WSN sends and receives information. The endtoend secure low energy adaptive clustering hierarchy (ELEACH) protocol is a hierarchical routing protocol algorithm proposed to solve highenergy dissipation problems. Other methods that explore the presence of the most powerful nodeson each cluster as cluster heads (CHs) are the sparsityaware energy efficient clustering (SEEC) protocol and an energy efficient clusteringbased routing protocol that uses an enhanced cluster formation technique accompanied by the fuzzy logic (EERRCUF) method. However, each CH in the ELEACH method sends data directly to the base station causing high energy consumption. SEEC uses a lot of energy to identify the most powerful sensor nodes, while EERRCUF spends high amounts of energy to determine the super cluster head (SCH). In the proposed method, a CH will search for the nearest CH and use it as the next hop. The formation of CH chains serves as a path to the base station. Experiments were conducted to determine the performance of the MELEACH algorithm. The results show that MELEACH has a more stable and higher throughput than SEEC and EERRCUF and has a 35.2% better network lifetime than the ELEACH algorithm. KCI Citation Count: 0
