In the present paper wireless sensor network for hierarchical network protocol of LEACH and HEED this is theory concept that how to data gathering. The authors' protocol aims to dynamically change the data Gathering period according to the Gathering quality. The timing scheme will find the minimum Gathering period that satisfies the sink's request. This protocol is work on this and how to easy maintain from both of them. The LEACH (Low Energy Adaptive Clustering Hierarchy) protocol presented in is an elegant solution where clusters are formed to fuse data before transmitting to the base station. They propose a new energy-efficient approach for clustering nodes in ad-hoc sensor networks.
