Bhatt Bhargavi, Chandresh R. Parekh · IOSR Journal of Computer Engineering · 2014
Wireless sensor network is vast area for research.Because of scarce resources, energy consumption and battery lifetime is crucial aspects in WSN.So with the help of routing protocol, improvement can be done.More energy can be conserved and network lifetime can be improved by modifying the existing protocols.Power Efficient GAthering in Sensor Information System (PEGASIS) is an improvement of hierarchical protocol.It mainly focuses on network lifetime.It uses chaining construction and data gathering approach to communicate.Aggregated data will pass on to the head node and it will pass the data to the base station.This paper introduces the PEGASIS, discusses the related previous work.New aspect of PEGASIS in heterogeneous environment is proposed.The new scheme is proposed in order to conserve energy.
