Opportunistic Routing for highly Mobile Ad-hoc Networks


Today's wireless mobile telecommunication networks are rather static. In most cases, the network nodes such as base stations are interconnected by fixed lines and only the last link between base station and mobile end system is wireless. We envision future application scenarios where highly mobile nodes such as Unmanned Aerial Vehicles(UAV) form highly mobile ad-hoc networks. Multimedia information such as real-time high-resolution video is carried across these wireless multi-hop networks formed by UAVs and infrastructure networks to/from the user. Such networks with nodes that have sensing capabilities can nicely support environmental monitoring applications and can be used for disaster and emergency operations. Existing mobile ad-hoc networks protocols are not appropriate for the envisioned scearios, because a packet source is unable to calculate a complete route to the destination as it is done in today's MANET routing protocols. The high mobility of a network consisting of UAVs requires new routing protocols, which can handle the fast topology changes. In this project we will investigate, develop and evaluate novel routing and forwarding schemes based on opportunistic routing schemes. Opportunistic routing protocols do not calculate an end-to-end communication path, forwarding is performed on hop-by-hop basis. An appropriate topology control protocol is also needed to mantain a basic connectivity to applu the opportunistic routing protocol. Geographic information could be applied to exploit multi-channel capabilities to reduce the interference and maximize throughput. Besides the simulations of mechanisms and protocols to evaluate the scalability, real implementations using UAVs and inter-connected test-beds has to be performed in order to prove feasibility of the developed concepts.

This project will be performed in the context of SNF PROJECT. 200021-130211.
