ACHs-LEACH: Efficient and Enhanced LEACH protocol for Wireless Sensor Networks

One of the buzzwords in the advanced information technology is IoT, which will transform the real world objects into intelligent virtual objects. IoT needs to support Device heterogeneity, Scalability, Ubiquitous data exchange through proximity wireless sensor technologies, Energy optimized solutions, Localization and tracking capabilities, Self-organization capabilities, Semantic interoperability and data management, Embedded security and privacy preserving mechanisms and hence challenging. Clustering plays an important role in the IoT architecture with the idea of creating collaborative, multi-hop and dynamic interactions among the heterogeneous objects. In this paper, our work focuses on providing an efficient means of communication between homogeneous devices through an efficient clustering mechanism and how efficiently clusters can be formed in a mobile and dynamic homogeneous wireless networks. In this work, we proposed a modification in the prominent wireless sensor network's routing protocol i.e. LEACH and Modified-LEACH(M-LEACH) and named as ACHs-LEACH technique which out performs as indicated in the performance metrics such as energy consumption, throughput, packet loss, packet delivery ratio. The work focuses on electing the Cluster- Head(CH) and Assistant Cluster Heads(ACHs) to reduce the energy consumption of the network so as to prolong the lifetime of the network. We also tried implementing the malicious nodes elimination which may cause problem for the integrity of the data and re-clustering of the entire network when a mobile node moves into another cluster.
