The Comparison between Leach Protocol and Pegasis Protocol based on Lifetime of Wireless Sensor Networks

Energy efficiency of the wireless sensor network mainly depends on the Routing protocols. In this paper two hierarchal protocols are used. There are various hierarchal protocols but we will discuss the two protocols i.e. LEACH and PEGASIS. Low Energy Adaptive Clustering Hierarchy (LEACH) and Power Efficient Gathering in Sensor Information System(PEGASIS). Hierarchal protocol uses the data aggregation clustering. Data aggregation is a process to reduce the duplicity of data transmission. Comparison is to be done between the Leach protocol and Pegasis protocol in terms of energy efficiency using Matlab.
