Abstract: Wireless Sensor Network (WSN) is one of the rising domain in modern times that is regularly improving. WSN is a resource-constrained network in terms of energy consumption. To improve the lifetime of the sensor network, the energy consumption should be as less as possible. An efficient routing routes the sensed data from source to destination with minimum energy dissipation. Hierarchical routings are one of those which routes the data with less energy consumption. Two such popular hierarchical routing protocols are named as LEACH (Low Energy Adaptive Clustering Hierarchy) and PEGASIS (Power-Efficient Gathering in Sensor Information Systems). LEACH is cluster-based, and PEGASIS is a chain-based protocol, where there are leader nodes in both cases which collect the information from the member nodes and forward the aggregated information to the Base Station (BS). In this paper, we have compared both the existing protocols based on network lifetime and discussed the required modifications which made them more efficient.
