Comparative study of WSN Protocols (LEACH, PEGASIS and TEEN)

With this study three “Wireless Sensor Networks” protocols are being reviewed on the basis of their functioning. “Low Energy Adaptive Clustering Hierarchy” (LEACH), “Power-Efficient Gathering in Sensor Information System” (PEGASIS) and “Threshold Sensitive Energy Efficient Sensor Network” (TEEN) are some of the WSN protocols. As these network protocols use hierarchical structure to achieve their functioning and gain energy efficiency, it makes it interesting to study about them. Included in this paper are four performance metrics namely “Hop count”, “Expected Transmission Count”, “Expected Transmission Time” and “Energy Consumption” which are elaborated and used to compare these three protocols. Finally, we make a General analysis for the protocols with respect to the performance metrics and further create a generalized view and what the future scope of this paper stand to be. Thus, this paper will provide comparative study between three of Wireless Sensor Network´s Protocols, LEACH, PEGASIS and TEEN.
