Peer-to-Peer (P2P) can support service for lots of end users with little hardware investment, which suits for the efforts to lower down the service cost for Multiplayer Online Games (MOG). In this paper, we introduce PKTown, a P2P middleware inserted into Star Craft and the network layer. PKTown captures all packets generated by Star Craft. Application Layer Multicast (ALM) is a popular techniq...

In this work we propose a family of trajectory tracking controllers for marine craft in the port-Hamiltonian (pH) framework using virtual differential passivity based control (v-dPBC). Two pH models of marine craft are considered, one in a body frame and another in an inertial frame. The structure and workless forces of pH models are exploited to design two virtual control systems which are rel...
