| dc.description.abstract | Sensor network features low-cost tiny sensor devices with wireless network capability, limited battery energy and resource constraints. The communication in Wireless Sensor Network (WSN) is handled by routing protocols. Among the WSN routing protocols, Low-Energy Adaptive Clustering Hierarchy (LEACH) is widely used benchmark cluster-based routing protocol. LEACH relies on the cluster head to perform data aggregation and transmission to the base stations. However, the performance of LEACH deteriorates with large-scale networks. Moreover, most of the current LEACH-based protocols uses Time Division Multiple Access Medium Access Control (TDMA MAC). Where slot for each cluster nodes has been assigned, even though some nodes might not have data to broadcast and that wastes the network resources. Furthermore, these protocols do not consider the cluster head (CH) overload problem. This study proposes adaptive clustering hierarchy routing protocol based on LEACH known as Energy-Efficient Scalable Routing Protocol (EESRP). The broad goal of proposing EESRP is to maintain the network-lifetime over the network expansion. EESRP introduces a three-layer hierarchy (i.e. sensors, congregations, and cluster heads) as well as applying multi-hop intra-clustering communication based on a hybrid MAC protocol. The EESRP is developed via a simulation testbed using MATLAB 2015a software. To assess the proposed protocol, a performance evaluation of EESRP with respect to Cell-LEACH, Multi-LEACH and BCDCP protocols is carried out. The validation is based on seven case studies (100, 200, 400, 800, 1600, 3200 and 6400 nodes scenarios) over ten simulation runs. Three evaluation metrics are chosen for the assessment, namely energy efficiency, energy consumption balancing and network scalability. Considering the network lifetime, the worst case of EESRP protocol is 41.4%, 50.4%, 57%, 58.8%, 69.7%, 72% and 75.4% better as compared to the best case of Cell-LEACH. Also, the worst case of EESRP protocol is 11.7%, 26.2%, 30.3%, 33.1%, 42.1%, 46.1% and 44.5% better as compared to the best case of Multi-LEACH. Further, worst case of EESRP protocol achieves 44.5%, 52.2%, 57.3%, 54%, 62.7%, 62.7% and 63.3% better than the best case of BCDCP. Moreover, the multi-hop intra cluster communication and the hybrid MAC showed that EESRP protocol has better load distribution and reduced the energy exhausting gap between cluster heads and cluster members. The obtained results confirm that the proposed EESRP protocol is suitable in both small and large WSN. | en_US |
