Paper Title
Improvement of NFCA an Energy Efficient Routing Protocol by Combining Modleach and Pegasis in WSN

Abstract
This paper presents a modified design of Nearest Fixed Clustering Algorithm which is a combination of 3 different energy-efficient routing protocols, ModLEACH (Modified Low energy adaptive clustering hierarchy), PEGASIS (Power-Efficient Gathering in Sensor Information Systems) and NFCA (Nearest Fixed Clustering Algorithm) which forms fixed clusters is proposed to boast the performance even more, considering metrics of throughput, network life and cluster head replacements. Energy consumption, average packet delivery ratio, throughput for ModLEACH, PEGASIS, are measured independently, and NFCA by combining ModLEACH and PEGASIS in WSN with more number of nodes to transmit the packets from source to destination are implemented and outputs are shown using comparison graphs.
