Small unpiloted aircraft (UAVs) each have limited power budgets. If a group (swarm) of small UAVs is organised to perform a common task such as geo-location, then it is possible t...
We report on the design, implementation, and evaluation of a system called Cedar that enables mobile database access with good performance over low-bandwidth networks. This is acc...
A classic result of Johnson and Lindenstrauss asserts that any set of n points in d-dimensional Euclidean space can be embedded into k-dimensional Euclidean space -- where k is lo...
We have been developing a mobile passenger support system for public transport. Passengers can make their travel plans and purchase necessary tickets by accessing databases via th...
In mobile computing environments, as a result of the reduced capacity of local storage, it is commonly not feasible to replicate entire datasets on each mobile unit. In addition, ...
