Performance of Clustering based Data Congregation in Wireless Sensor Networks

Abstract

Wireless Sensor Networks (WSNs) play an essential role in today s real world newlineapplications. The effectiveness of the WSNs lies in their sensing quality, energy newlineconsumption, flexibility, scalability, network lifetime, coverage etc. The goal of such newlineWSNs deployed in the above environments is to deliver the sensing data from sensor newlinenodes to the sink node in the communication network. newlineWSN monitor physical or environmental conditions for example weather, newlinepressure, sounds, movement, pulsation and energy hole. It is a critical concern for data newlinecongregation. A Performance of Clustering based Data Congregation is required to newlinesolve the problem on a large-scale WSN. This research work mainly concentrates on newlineeffective data gathering and routing of the collected data from sensor to a base station. newlineThree novel methods aimed at design the clustering based data aggregation newlinetechniques are proposed in this research work for WSNs. They are: Tree Cluster newlineBased Data Gathering Scheme (TCDGS) in WSN; Enhanced Three Layer Energy newlineEfficient Clustering (ETLEEC) Algorithm in WSN and Novel Cluster Based Energy newlineProficient Data Aggregation. newlineThe first among the three protocols is Tree Cluster Based Data Gathering newlineScheme (TCDGS) in WSN. The main objective of this algorithm is to improve the newlineQuality of Service of the communication network. The sink selects the data gathering newlinenode based on the threshold value, connection time, received signal strength, newlinecommunication range and heftiness for connection which reduces the surplus energy newlineusage and traffic of the whole network. TCDGS improves the energy efficiency and newlinenetwork lifetime of the network with minimum amount of delay. newlineSecondly, Enhanced Three Layer Energy Efficient Clustering (ETLEEC) newlineAlgorithm in WSN is proposed. The ETLEEC method uses an extra layer called the newlinelattice head where the cluster head collects the information form sensor nodes and newlinesends it to the lattice head which in turn is sent to the base station. The main intent of newlinevi newlinethis proposed work is to prolong the lifetime of a sensor network for a given fixed newlineamount of energy. newlineFinally, to reduce the energy consumption and to avoid the redundant newlineinformation a novel Cluster Based Energy Proficient Data Aggregation technique is newlineimplemented. The member nodes in the cluster send the collected information through newlinehigh link connectivity nodes to the Data Depositor present near the cluster head. The newlinecryptographic key technique provides secure data transmission to the network. newlineA comparative analysis of the three protocols: TCDGS, ETLEEC, CBEPDA newlineare performed. All simulations are achieved in the network simulator tool that uses newlinevarious scenarios (0.000083 density and 0.000116 density) for comparison against newlinebaseline protocols. There is a lot of scope for research with the increasing usage of newlineWSNs and scope for further study is also suggested for implementation. newline
