Abstract

Objectives: A Wireless Sensor Network (WSN) plays an important role in the future wireless communication domain because of its properties, which includes intelligence, cheaper and smaller in size. With the wireless interfaces, these can communicate with each other in case of cooperative communication in a single or multiple networks. Methods/Statistical Analysis: As multiple nodes are required for cooperative communication, the Low Energy Adaptive Clustery Hierarchy (LEACH) Protocol is used for cluster formation. Further Vector Quantization (VQ) is used for analysis of low energy path for the nodes and clusters respectively. Findings: The main issue of inter-cluster node communication is carried out in earlier work using LEACH protocol. The proposed technique illustrates the LEACH-Vector Quantization (LEACH-V) protocol for intra-cluster communication in a cooperative communication network. Application/Improvements: As per the application point of view, LEACH-V performs the lowest energy path for intra-cluster communication. LEACH provides the optimum cluster size and their Cluster Head and using VQ, the minimum distance is calculated using Euclidean distance between the multiple cluster heads which creates the shortest path results in energy efficient technique. Further, the spectral distortion of the proposed technique has been analyzed for practical implementation.
