Research projects : Routing protocol in Mobile Ad hoc NETwork
A novel routing protocol for Wireless Mobile Ad Hoc Networks, named Virtual Distance Vector, is under development. This protocol augments AODV with a virtual overlay, unrelated to the actual network topology, which accounts for routes kept proactively by mobile nodes acting as scouts toward the nodes in the respective subsets of peers.
This provides routes from any source to any destination node, along which data packets can be routed without the need of preliminary route discovery. The intended goal of VDV is to reduce the average end-to-end delivery time of data packets.

A preliminary version of VDV has been already evaluated against AODV by running extensive simulation under OPNET Modeler. Simulation confirmed the expected advantage of VDV, which increases with increasing node mobility and average route length. The confidence intervals of reported data showed that VDV fits better the dynamic nature of the network.
