Enhancement in the performance of routing protocols for wireless communication using clustering, encryption, and cryptography

Abstract

The field of wireless communication sensor networks has been a keen area of research in the last decade. One of the crucial and important parameters for efficient operation of any wireless network is the routing algorithm. Advances in electronics and telecommunication industry in the last few decades have tremendously increased the use of wireless communication systems. However, the choice of the routing algorithm depends not only on the physical topology and geography of the network but also on the application. This paper presents enhancement in the performance analysis of various routing protocols, namely AODV, AOMDV, DSDV, and DSR. These protocols are analyzed on the basis of four quality of service parameters, namely throughput, jitter, delay, and energy consumption. After analyzing, we found that AODV is having the best overall performance. Further enhancement in the QOS parameters of AODV is done with the help of cluster-head selection, encryption, and cryptography which are applied to improve the performance of protocols and the enhanced results are shown in this paper with the help of graphs and analysis.
