Routing in Mobile Ad-hoc Networks - A Comprehensive Research

From the last decade, there has been expeditious growth and a worldwide success is perceived in the area of wireless ad-hoc networking. Especially, one class of wireless ad-hoc networks, that is, mobile ad-hoc network (MANET) drawing a great attention from the critical applications like emergency search and rescue operations and disaster recovery services. A MANET consists of mobile nodes that are capable of self-configuring the network instantly. However, the MANETs, containing wireless mobile ad-hoc nodes that are connected by multi-hop communication process, make routing the data packets in them a challenging task. In this paper, the essentials of unicast and multicast routing in mobile ad-hoc environments are focused. Moreover, the working principles of four eminent routing protocols such as DSDV, OLSR, DSR, and AODV have been presented in detail.
