ABSTRACT
A routing protocol in ad hoc wireless networks must take special consideration to link failure and route maintenance in order that the network services will not be interrupted. To decrease the link failure, Anticipated Route Maintenance Protocol (ARM) has been proposed. However, the detailed performance for this protocol has not been evaluated. In this paper, we have compared the performance of two protocols, standard Dynamic Source Routing Protocol (DSR) and a combination of DSR and ARM. The simulation results show how ARM improves the functionality of DSR by preventing the links in the route from breaking. Packets delivery ratio could be increased using ARM maintenance and achieved approximately 100% improvement. The simulations clarify also how ARM shows a noticeable improvement in dropped packets and links stability over DSR, even though there is more traffic and channel overhead in ARM.

An improvement in performance of mobile ad hoc networks using modified route maintenance
A mobile ad hoc network (MANET) is a temporary network where nodes are free to move in a given area. Due to this dynamic nature, links in the routes break. Often backup routing is used as a solution in which alternate route tables are used to continue ...
Performance evaluation and comparison of different ad hoc routing protocols
A Mobile Ad Hoc Network (MANET) is a dynamic wireless network that can be formed without the need for any pre-existing infrastructure in which each node can act as a router. One of the main challenges MANET is the design of robust routing algorithms ...
Performance evaluation of H.264 protocol in ad hoc networks
Wireless mobile ad hoc network data transmission between multiple senders and receivers is becoming increasingly important in nowadays networks. There are many applications for sending data from a single source to multiple destinations (e.g. ...
