Hybridizing Pegasis Protocol With Leach-1r Using Inter-cluster And Intra-cluster Chains

Résumé: Wireless Sensor Networks (WSNs) consist of small nodes with sensing, computation, and wireless communications capabilities. These sensor nodes are inexpensive portable devices with limited processing power and energy resources. Routing is one of the new key technology which has become a hot research nowadays since the applications of WSNs are growing everywhere. Hierarchical routing in wireless sensor networks (WSNs) is a very important topic that has been attracting the research community in the last decade. Typical hierarchical routing is called clustering routing, in which the network is divided into multiple clusters. Recently, some types of atypical hierarchical routing arise, including chainbased, tree-based, grid-based routing, and area-based routing. In our work, we proposed a set of hierarchical hybrid protocols between clustering-based LEACH-1R protocol and chainbased PEGASIS protocol. Where we aim to enhance the lifetime of the network. For experimental results, we implemented the existing LEACH-1R and PEGASIS protocols as well as four hybridized protocols using the MATLAB environment in order to compare them vis-à-vis the energy consumption and the lifetime of the network. Experimental results showed that hybridization that implements cluster external chain overcomes other hybrid models as well as the original protocols in terms of maximizing the network lifetime.
