Widely deployed multimedia services are expected to accommodate clients in a highly heterogeneous environment. Clients of a multimedia service may vary greatly in processing and c...
A number of protocols have been proposed to date to defend against wormhole attacks in wireless networks by adopting synchronized clocks, positioning devices, or directional antenn...
We introduce the Composite Endpoint Protocol (CEP) which efficiently composes a set of transmission elements to support high speed flows which exceed the capabilities of a single...
Large Virtual Worlds (VWs) are increasingly common in the computer graphics areas of simulation, games, geospatial or scientific visualisation. In such VWs, simulated motion of th...
We present the first local approximation schemes for maximum independent set and minimum vertex cover in unit disk graphs. In the graph model we assume that each node knows its geo...
