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 (UAVs) 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 the 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. They build a self-organizing communication infrastructure. Existing mobile ad-hoc network (MANET) protocols are not appropriate for the envisioned scenarios, 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. We aim to investigate how to support wireless multi-hop networks with nodes that are highly mobile, i.e. the nodes move with high speeds (at least as fast as cars), move into rather different directions and move in a three-dimensional space. The project 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. In order to maintain a basic connectivity required to apply the (opportunistic) routing protocol, we aim to develop an appropriate topology control protocol that not only achieves connectivity but also minimizes interference among nodes. We propose to design this topology control protocol based on the concept of virtual springs, where forces between UAVs are established based on the received signal strength indication. Moreover, we aim to develop a geographic opportunistic routing protocol exploiting multi-channel capabilities to reduce interference and maximize throughput. We intend to use information like flight direction, speed, altitude or angular velocities to optimize the routing decisions at the receiver. Besides simulations of mechanisms and protocols to evaluate scalability, real implementations using unmanned aerial vehicles and interconnected test-beds has to be performed in order to prove feasibility of the developed concepts. To support development, testing, and performance evaluation, we aim to develop an emulation platform that allows emulating high node mobility and that can execute the same code to be deployed on the real UAVs. Quad-rotor helicopters as emerging rotorcraft concept for UAV platforms will be used for real-world implementations, tests, and evaluations. They are equipped with position sensors like GPS receivers, compass, ultrasonic distance sensors or cameras for autonomous flight inside of a defined area. The development and the evaluation of our high mobility supporting routing protocol will be made in three steps. First, we will implement and simulate the routing protocol in a network simulator (OMNeT++) with a three-dimensional mobility framework. Appropriate mobility models need to be derived from identified application scenarios. Second, we will implement the routing protocol for the target platforms and emulate them on our emulation environment. Third, we will use real mesh nodes and UAVs to test our developed protocols.
