Improvement of Network Lifetime using Clustering and Dynamic Topology Methods in WSN

Abstract

In the contemporary era, there are plethora of applications that rely on newlineWireless Sensor Networks. WSN is ubiquitous in nature and being used in Internet newlineof Things (IoT) use cases as well. However, such networks have inherent problems newlinedue to constrained resources, mobility and channel strength issues. Improvement of newlinenetwork lifetime by using energy efficient methods in routing and other newlinemechanisms is given paramount importance. newlineThe existing methods focused on achieving this through clustering and newlinetopology control. Nevertheless, it is indispensable to optimize them further for newlineleveraging life span of WSN by conserving energy as the nodes in network run with newlinebattery power. From the literature, different research gaps are identified. First, there newlineis room for improving clustering mechanism for reducing energy consumption. newlineSecond, topology control on top of clustering could bring about further enhancement newlineof life span of network. This hypothesis needs to be tested. Third, often neglected newlinearea, control overhead reduction in routing protocol has wherewithal to reduce newlineenergy consumption. It is yet another hypothesis which deserves testing. newline
