Optimizing Route Length in Reactive Protocols for Ad Hoc Networks

چکیده
Many protocols for Mobile Ad-hoc Networks propose construction of routes reactively using flooding. The advantage hereof is that no prior assumption of the network topology is required in order to provide routing between any pair of nodes in the network. In mobile networks, where the topology may be subject to frequent changes, this is a particularly attractive property. In this paper, we investigate the effect of using flooding for acquiring routes. We show that flooding may lead to non-optimal routes in terms of number of hops. This implies that more retransmissions are needed to send a packet along a route. We proceed by providing a qualitative analysis of the route lengths. Finally, we propose alternative flooding schemes and evaluate these schemes through simulations. We find that using these schemes, it is indeed possible to provide shorter routes.

Mobile ad hoc networks are networks composed of wireless devices to create a network with the ability for self-organization. These networks are designed as a new generation of computer networks to satisfy some specific requirements and with features different from wired networks. These networks have no fixed communication infrastructure and for communication with other nodes the intermediate no...

In Wireless Ad-hoc Networks, nodes are free to move randomly and organize themselves arbitrarily, thus topology may change quickly and capriciously. In Mobile Ad-hoc NET works, specially Wireless Multi-hop Networks provide users with facility of quick communication. In Wireless Multi-hop Networks, routing protocols with energy efficient and delay reduction techniques are needed to fulfill users...
متن کاملOptimizing Route-Cache Lifetime in Ad Hoc Networks
On-demand routing reduces the control overhead in mobile ad hoc networks, but it has the major drawback of introducing latency between route-request arrival and the determination of a valid route. This paper addresses the issue of minimizing the delay in on-demand routing protocols through optimizing the Time-to-Live (TTL) interval for route caching. An analytical framework is introduced to com...
