Description: A Vehicular Ad-Hoc Network (VANET) is a network where vehicles can disseminate
information such as traffic conditions, availability of free parking lots or content.
In order to fulfill VANET application requirements (Time To Live (TTL), information
distance spread), we need to use the available network resources (e.g., radio
capacity) optimally depending on the traffic conditions. While cellular-based approaches
(e.g., 3rd Generation mobile telecommunications (3G)) is suited for low
traffic conditions, dense traffic (where users might already use 3G) is particularly
suited for relying on Vehicle-to-Vehicle (V2V) communication (e.g., ad-hoc WIFI).
There is a clear need to adapt the dissemination strategy to the current traffic conditions
and application requirements. The optimal solution is based on combining
or alternating between cellular-based and opportunistic dissemination strategies.

-The course and track control of unmanned surface vehicle (USV) is important to
improve the observational effect of the recon reconnaissance equipment and the multi-
-mission operational capability. Because of the effects of wind, wave and flow, the
unmanned surface vehicle will produce six degrees of freedom movement which has
randomicity and nonlinearity. It is difficult of the course, track and attitude control of
unmanned surface vehicle, so six degrees of freedom movement model is built for the
better control of unmanned surface vehicle.
According to the classic MMG s separated modeling theory and the horizontal
body axes system which was developed by Hamamoto, this thesis describes a six
degrees of freedom motion equation of unmanned surface vehicle. Through analyzing
the hydrodynamic force and moment, the fluid inertia force model, the fluid viscous
force model, propeller thrust model and steering gear model are built respectively.
