A novel routing scheme for mobile ad hoc networks (MANETs), which combines the ondemand
routing capability of Ad Hoc On-Demand Distance Vector (AODV) routing protocol
with a distributed topology discovery mechanism using ant-like mobile agents is proposed
in this paper. The proposed hybrid protocol reduces route discovery latency and the end-toend
delay by providing high connectivity without requiring much of the scarce network
capacity. On the one side the proactive routing protocols in MANETs like Destination
Sequenced Distance Vector (DSDV) require to know, the topology of the entire network.
Hence they are not suitable for highly dynamic networks such as MANETs, since the topology
update information needs to be propagated frequently throughout the network. These
frequent broadcasts limit the available network capacity for actual data communication. On
the other hand, on-demand, reactive routing schemes like AODV and Dynamic Source
Routing (DSR), require the actual transmission of the data to be delayed until the route is
discovered. Due to this long delay a pure reactive routing protocol may not be applicable
for real-time data and multimedia communication. Through extensive simulations in this
paper it is proved that the proposed Ant-AODV hybrid routing technique, is able to achieve
reduced end-to-end delay compared to conventional ant-based and AODV routing protocols. |
