Project Description: The potential of Mobile wireless Adhoc Networks (MANET) is significantly high. The application of MANET to areas such as emergency rescue, environmental observation, scientific investigations, commercial environments, home and enterprise networking, educational applications, entertainment, military operations and location-aware services holds great promises. The automatic adaptation of the network topology to the field context provided by MANET, make these a great asset in providing local connectivity. However, these applications often happen in infrastructure-less or remote regions where remote connectivity to the outside world has to be provided by some other means.

Satellite is one of the solutions to provide this remote connectivity and sometimes the only solution for the MANET to communicate with other parts of the world. Current expectations dictate that satellite will be seen not only as a component of an alternative routing path but also as part of a unique (really integrated) system. Examples of the benefits of satellite include IP via satellite in regions with no access to terrestrial DSL, new architectures for near-video on demand, satellite networks integrated with WiFi, WiMAX, LTE or TETRA, or satellite networks backhauling collectively mobile networks in ships, trains, or airplanes.

The concept of a hybrid MANET-Satellite network is therefore a natural evolution of considering the problem of providing local and remote connectivity in a highly mobile, dynamic and often remote environment. This combination raises, nonetheless, significant challenges in terms of optimising network resources, link availability, providing Quality of Service (QoS) and Quality of Experience (QoE) (the subjective measure of a customer’s experiences with a service supplier) and minimizing costs and energy.

Issues such as the re-organisation of MANET to connect to satellite access points, re-organisation of the satellite access points, selection of which satellite access points to use, the use of satellite as a relay between two MANET, the adjustment of routing in accordance with the current network situation and the exchange of cross layer information to improve resource management are some of the challenges which we feel require investigation. MONET will study these challenges, propose and develop solutions for the optimization of a hybrid MANET-Satellite network, implement a prototype of the most promising solutions and test them in the field, in near real-life conditions.
