Routing Protocol in Mobile Ad-Hoc Networks: A Review

Uma Bharti, Mohit Trehan


Failure of wireless link is considered as one of popular challenges faced by Mobile Ad-Hoc Networks (MANETs). Whereas this type
of networks does not have any fixed routers or any pre-exist infrastructure. Also, every node is capable of movement and can be connected to
other nodes dynamically. Therefore, the network topology will be changed frequently and unpredictably according to continuous interaction
between nodes that simultaneously affect network topology in the basis of dynamic ad-hoc nature. This factor puts routing operation in critical
area of research under mobile ad-hoc network field due to highly dynamic environment. To adapt this nature, MANETs demand new routing
strategies to occupy these challenges. Thereafter, huge amount of protocols are proposed to argue with ad-hoc requirements. Thus, it is quite
difficult to specify which protocols perform better under different mobile ad-hoc scenarios. This paper examines the prominent routing protocols
that are designed for mobile ad-hoc networks by describing their structures, operations, features and then comparing their various characteristics.
