Comparative analysis of Energy Efficient Routing Protocol over WSN

With the widespread use of WSNs, it has become very important for routing to use energy efficiently. The efficient use of energy by routing directly affects the life span of WSN. Most of the studies in the literature have focused on increasing energy efficiency. In this study, energy sensitive Routing protocols are focused. The goal is which protocol will save energy more efficiently. All Routing protocols analysed are all about collision prevention, eliminating latency and solving existing energy sensitive problems. Despite all these developments, there are no standard MAC protocols for WSNs yet, but a lot of work is being done on this subject. The main purpose of the envisaged MAC protocols is to find a solution to the energy problem that determines the life span of the WSN. It is to seek new ways and methods to minimize energy waste. In addition, efforts are also made to reduce the transmission delays that occur in applications that are effective against delays. This paper introduce a comparative analysis of routing protocols over different network scenarios and yield interesting facts regarding capabilities and deficiency of these protocol over different network density.
