Review on State-Of-The-Art of PEGASIS Protocol in WSNS

Abstract

Wireless Sensor Networks (WSNs) have been widely considered as one of the most important technologies for the twenty first century. Due to the advancements in microelectronic mechanical systems (MEMS) and wireless communication technologies, it has become possible to deploy tiny, cheap, and smart sensors in any physical area. The routing is one of the dominant factors which decide the fate of limited battery resources in WSNs. In this paper, a review on the state-of-the-art on PEGASIS (Power efficient Gathering in Sensor Information System) protocol has been presented. PEGASIS is highly significant in small areas applications, some of the variants of PEGASIS protocol has been studied in this paper. After studying various protocols, it has been found that Chain Based Cluster Cooperative Protocol (CBCCP) has tremendously improved network lifetime by incorporating cluster based concept in routing. Although it has outperformed various routing protocols but it still leave a great margin of improvement in the inter cluster communication. This paper basically focuses on reflecting the significance of chain based protocols in WSNs.
