Routing Protocols in MANET: An Overview
Gunseerat Kaur, Poonam Singh Thakur · 2019
Mobile Ad-hoc Networks also known as MANETs belong to a collaborative collection of different mobile devices from a heterogeneous network, the prolific feature is the capability to join and quit the network any time. This leads to a creation of a decentralized network of mobile nodes which can connect, communicate and pass messages to each other without the requirement of an intermediate router. MANETs have the provision to offer much quicker deployment as compared to a normal networks, the deployment being horizontal type is only possible in this scenario. MANETs are generally used in diverse set of applications like Military operations, emergency or disaster relief operations, business meetings, political meetings, Mine cite operations. In these kinds of networks the most important issue is that of finding the best route available between the two nodes according to the user requirements. Undoubtedly routing protocols and their evaluation is the most discussed topics in the MANETs since the evolution of this network. A number of enhancements have been done to these basic protocols being discussed here by different researchers from time to time according to their requirements. But this paper tends to throw some light on the basic protocols which will provide the readers the basic information about the characteristics, advantages and disadvantages of the particular protocol and can help them to use any protocol according to their use. An intention is to discuss regarding the proactive, reactive, hybrid, location-based, power aware, uni-cast, multicast; covering apparently major number og routing protocols been proposed so far. This paper tends to cover the routing protocol covering the timeline from last two decades. In the conclusion we will give the table showing the comparison of various discussed routing protocols. We hope that this paper will help the researchers in the area of Adhoc networks.
