Enhanced dominant pruning applied to the route discovery process of on-demand routing protocols

چکیده
Dominant Pruning (DP) is a distributed connected dominating-set algorithm that can be used for reducing the impact of flooding in wireless ad hoc networks. We propose an enhanced dominant pruning (EDP) approach to be used in the route discovery process of on-demand routing protocols. To show the benefits of EDP, we integrate EDP into the Ad-hoc On-demand Distance Vector (AODV) protocol. We present detailed simulation results showing that our approach improves standard AODV in most aspects, and that it is simple and easy to implement. Our approach is compared against AODV and OLSR, as good representatives of on-demand and proactive routing for ad-hoc wireless networks.

Enhancing the Route Discovery Process of On-Demand Routing in Networks with Directional Antennas
The route discovery process of on-demand routing protocols is based on route request (RREQ) packets that are propagated using either an unrestricted broadcast (flooding) or an expanding ring search. We apply two enhancements to this basic process aimed at reducing the overhead incurred in the dissemination of RREQs. First, we apply the Enhanced Dominant Pruning (EDP), which is a distributed con...
متن کاملMultipath Node-Disjoint Routing with Backup List Based on the AODV Protocol
In recent years, routing has been the most focused area in ad hoc networks research. On-demand routing in particular, is widely developed in bandwidth constrained mobile wireless ad hoc networks because of its effectiveness and efficiency. Most proposed on-demand routing protocols are built and relied on single route for each data session. Whenever there is a link disconnection on the active ro...
متن کاملEnhanced DSR for MANET with Improved Secured Route Discovery and QoS
Mobile Ad hoc NETwork (MANET) comprises of nodes, which are free to move randomly, yet cooperate to forward packets between source and destination over a multi-hop wireless network. Due to absence of any fixed node, each node acts as a router, providing routing capability for the MANET. Various protocols for discovery of routes between any two MANET nodes have been designed. These protocols are...
متن کاملTrusted AODV Protocol against Blackhole Attack in Wireless Ad-hoc Network
In On-demand routing protocols for wireless ad-hoc networks, whenever communication is needed, source discovers route for data delivery to destination. Blackhole attackers exploit the on demand route discovery process and data delivery by dropping the packets which are supposed to be forwarded by them. In this paper, we have proposed an enhanced AODV routing protocol, CAT-AODV-B (Context Aware ...
متن کاملDistribution of route requests using dominating-set neighbor elimination in an on-demand routing protocol
We investigate the use of dominating-set neighbor elimination as an integral part of the distribution of route requests using the Ad hoc On-demand Distance Vector (AODV) protocol as an example of on-demand routing protocols. We use detailed simulations to show that simply applying dominant pruning (DP) to the distribution of route requests in AODV results in pruning too many route requests in t...
