Enhanced chain-cluster based mixed routing algorithm for wireless sensor networks

Abstract EN

Energy efficiency is a significant aspect in designing robust routing protocols for wireless sensor networks (WSNs).

A reliable routing protocol has to be energy efficient and adaptive to the network size.

To achieve high energy conservation and data aggregation, there are two major techniques, clusters and chains.

In clustering technique, sensor networks are often divided into non-overlapping subsets called clusters.

In chain technique, sensor nodes will be connected with the closest two neighbors, starting with the farthest node from the base station till the closest node to the base station.

Each technique has its own advantages and disadvantages which motivate some researchers to come up with a hybrid routing algorithm that combines the full advantages of both cluster and chain techniques such as CCM (Chain-Cluster based Mixed routing).

In this paper, introduce a routing algorithm relying on CCM algorithm called (Enhanced Chain-Cluster based Mixed routing) algorithm E-CCM.

Simulation results show that E-CCM algorithm improves the performance of CCM algorithm in terms of three performance metrics which are: energy consumption, network lifetime, and (FND and LND).

MATLAB program is used to develop and test the simulation process in a computer with the following specifications: windows 7 (32-operating system), core i5, RAM 4 GB, hard 512 GB.
