Ad-hoc networks has opened a new dimension in wireless networks. It allows
wireless communication in the absence of central support of the contract. In these
networks, there are no fixed infrastructure because the mobile nodes are continuously
mak
ing continuous and dynamic change in the topology.
Routing protocols of mobile ad-hoc networks differ from the existing internet
protocols which are designed for the fixed structure based wireless networks. MANET
protocols have to face high challenges due to dynamically changing of topologies, low
transmission power and asymmetric links. Due to link instability, node mobility and
frequently changing topologies routing becomes one of the core issues in MANETs.
Currently existent routing protocols provide routing solutions up to a certain level
and most of them are designed and implemented in small areas. Many researchers are still
working on the developments of MANET routing protocols.
With the increase in the types of routing protocols used in mobile network it has
become necessary to study the effectiveness of each type of protocols In this papper we
compared between the most famous species (proactive, Reactive, hybrid) and choose a
protocol to be representative of all species previously mentioned and the network
performance assessment each type in terms of Throughput, dynamic routing routing, load,
delay and determine which of these protocols appropriate for each case.
