FLAT VS hierarchical routing protocols in wireless sensor networks: An in-depth analysis

Abstract

The emerging applications of IoT require that Wireless Sensor Network should be energy proficient. To build the Wireless Sensor Network more energy proficient, many challenging issues like routing, localization and sensor fusion must be properly addressed. Although many routing protocols are in existence, there is a lack of research papers that contain an in depth analysis which can give an overview to the current researchers. In order to provide a big picture outlook, we have put an effort to analyze the comparative performance of various leading routing protocols available in WSN. Although many routing protocols are available in the literature under flat routing, SPIN is selected under flat routing protocol as it’s a leading protocol. Similarly, LEACH, LEACH-C and PEGASIS is considered under hierarchical routing protocol. Simulations have been carried out by using the NS-2 simulator. The Performance metrics like energy utilization, delay, throughput and network lifetime are some of them which has been explored
