In this paper, we propose an adaptive and opportunistic forwarding mechanism that is able to match mobility characteristics in Delay Tolerant Networks (DTNs). Our protocol, Seeker, empowers nodes with the ability to estimate future contact opportunities based on a history of pair-wise contacts. Furthermore, Seeker is able to adjust and rewind forwarding and buffering decisions on the fly. This ...

Nomenclature β,γ(∈ S) = The gimbal and wheel angles. (rad) Rβ(∈ SO(3)) = Transformation from gimbal frame G to the spacecraft body frame B. Is = Spacecraft inertia without the CMG gimbal and wheel inertia. (kg.m) Ig, Ir = Gimbal frame inertia, wheel inertia about own centre of mass represented in gimbal frame. (kg.m) (Igr)β = Combined inertia of gimbal frame and wheel in the spacecraft frame. R...
