A Survey of Unipath Routing Protocols for Mobile Ad Hoc Networks

Abstract

A MANET (Mobile Ad hoc NETwork) is an interconnection of mobile devices by wireless links forming a dynamic topology without much physical network infrastructure such as routers, servers, access points/cables or centralized administration. Routing is a mechanism of exchanging data between the source node and the destination node. Several protocols are used to perform routing the information from the source node to the destination node. The main aim of this paper is to explore the working principles of each unipath routing protocol. The unipath routing protocols are divided into Table-Driven (Proactive), On-demand (Reactive), Hybrid routing protocols

A Survey of Routing Protocols for Ad Hoc Networks Based on Update Mechanism

“…The recipient modifies its distance and seeks the best route at the time of message receiving. Distance [1], [4], [7].…”

“…Less delay is involved in the route setup process because of the availability of routes to all destinations at all times. The existing wired network protocols are adaptable to ad hoc wireless networks because they can be made [1], [6], [7].…”

“…The following are some of the most important protocols like CEDAR, ZRP, and ZHLS. [14], [15] Core Extraction Distributed Ad Hoc Routing (CEDAR) protocol [1], [6] establishes a core nodes in the network which is used to transmit packets. The routing establishment uses reactive routing scheme and which performed by core nodes.…”

“…Better bandwidth utilization is possible because CGSR uses a partial coordination between nodes by electing cluster heads. Increases in path length and instability in the system at high mobility when the rate of change of cluster -heads is high [1], [7].…”

“…The necessity that the Routing Protocol must be able to respond rapidly to the topological changes in the network, this will help to get a wide understanding of the problem and can also be used to develop or to extend proposed schemes [1]- [3].…”
