Analysis of Optimization of Quality of Service Parameters in Wireless Sensor Network by Clustering Approach

Wireless Sensor Network is a very keen area for research. The factors that plays important role in affecting the performance of Wireless Sensor network are the quality of service parameters. The quality of service parameters plays the important role to judge the performance of Wireless Sensor Network. The important Quality of Service parameters are delay, jitter, throughput, packet delivery ratio and energy consumption. The problems and limitations existing in WSN in terms of Quality of Service parameters are like energy consumption by the routing protocols is very high further if we consider time related issues delay and jitter are high. In terms of security also they are not much secure. This paper proposes to overcome the problems and the limitations present in the existing routing protocols by improving the QOS parameters. This can be achieved by applying Clustering. This paper also presents the mathematical analysis of different routing protocols before and after applying the Clustering. Hence optimization of Quality of Service parameters leads to minimization of energy consumption, delay and jitters and hence enhanced the performance of WSN.
