Energy Efficient Clustering-based Routing Protocol Adopting Enhanced Cluster Formation (EERRCUF) Protocol in Hybrid Wireless Sensor Networks*

Wireless Sensor Networks is one such domains where lot of researches and development works have been carried out to enable powerful sensor nodes are available at low cost. Now a day, the Hybrid Wireless Sensor Networks have attracted the researchers to focus on communication difficulty between Static Sensor Networks (SSN) to Mobile Sensor Networks (MSN). In this paper energy efficient cluster based routing protocol adopting enhanced cluster formation (EERRCUF) protocol is introduced for the applications like HWSNs. Initially we perform the effective clustering process using Particle Swarm Optimization (PSO) for grouping the nodes according to the geolocation properties. By using PSO all the nodes will cluster without residual nodes, subsequently the cluster head (CH) and super CH based on the trusted valued of each node computed by the Differential Evolution based Trust Inference (DETI) model. Then, an inter-cluster routing is performed by Gravitational Search Algorithm (GSA). The simulation results showed effectiveness of our EERRCUF protocol in terms of Quality of Service (QoS) constraints such as throughput, delay, energy consumption; Quality of Experience (QoE) constraints such as Peak Signal-to-Noise Ratio (PSNR), Structural Similarity Index (SSIM), and Video Quality Measurement (VQM).
