Comparative Review for Routing Protocols in Mobile Ad-Hoc Networks

Wireless Mobile Ad-Hoc Networks is one of the attractive research field that growing exponentially in the last decade. it surrounded by much challenges that should be solved the improve establishment of such networks. Failure of wireless link is considered as one of popular challenges faced by Mobile Ad-Hoc Networks (MANETs). As this type of networks does not require any pre-exist hardware. As well as, every node have the ability of roaming where it can be connected to other nodes dynamically. Therefore, the network internal structure will be unpredictably changed frequently according to continuous activities between nodes that simultaneously update network topology in the basis of active ad-hoc nature. This model puts the functionality of routing operation in crucial angle in the area of research under mobile adhoc network field due to highly dynamic nature. Adapting such kernel makes MANET indigence new routing techniques to settle these challenges. Thereafter, tremendous amount of routing protocols proposed to argue with ad-hoc nature. Thus, it is quite difficult to specify which protocols operate efficiently under different mobile ad-hoc scenarios. This paper examines some of the prominent routing protocols that are designed for mobile ad-hoc networks by describing their structures, operations, features and then comparing their various characteristics
