Abstract

Background/Objectives: To develop a Least-Power Adaptive Hierarchy Cluster (LPAHC) framework which combines the energy-efficient cluster-based routing and improve network lifetime based on Channel State Information (CSI). Methods/ Statistical analysis: initially, the LPAHC framework obtained the CSI using the Frequency Division Multiplexing (FDMbased) Channelization technique. The FDM-based Channelization technique is applied with the objective of reducing the average energy cost adopts frequency bands to assign channel for each sensor nodes based on the traffic patterns. Then, based on the frequency bands assigned, the selection of cluster head is made by applying Adaptive Hierarchy Cluster with aiming at improving the network lifetime. Finally, communication between sensor nodes is made in an effective manner using Received Signal Indicator (RSI) from the cluster head. Findings: The experimental evaluation of energy efficient framework using LPAHC in WSN is measured in terms of density of sensors, energy consumption, network lifetime average energy cost and average delay time consumption. Application/Improvements: Compared to the tradition energy efficient frameworks in WSN, LPAHC framework is able to reduce the energy consumption for data communication between sensor nodes and reduce the average energy cost.
