QRE2PM: QoS Centric, Reliable and Energy-Efficient Routing Protocol for MANET

摘要

The high pace emergence in wireless communication systems and associated applications have given rise to a number of technologies serving certain targeted application environment. Amongst major wireless communication systems, Mobile Adhoc Network (MANET) has emerged as a potential solution to meet communication demands even with decentralized and infrastructure-less environment. Though, MANETs have been recognized as a potential system, very few efforts have been made to augment overall routing to ensure QoS demands, energy-efficiency and reliable communication. The available MANET routing protocols employ. classical clustering and single parameter based cluster head selection for data transmission, which is confined particularly for MANETs with large scale deployment and high mobility conditions. To alleviate such issues, this paper presents a highly robust QoS Centric, Reliable and Energy-Efficient Routing Protocol for MANET (QRE2PM). The proposed QRE2PM model employs grid-partitioning, dual phase centralized clustering model using Fuzzy Clustering Mean and Enhanced Expectation Maximization, multiple parameters based CH selection and signaling overhead reduction model. The use of multiple network parameters, including Inter-Node-distance, Node-Responsiveness, Residual Energy, and Signal-to-Noise Ratio for CH selection strengthens QRE2PM protocol to exhibit better performance. The performance outcomes in terms of throughput, delay, energy consumption and network efficiency reveal that the proposed QRE2PM protocol outperforms other state-of-art routing protocols.
