As mobile computing becomes ubiquitous and airspace more congested, it is increasingly important to fairly distribute bandwidth between competing wireless devices in order to ensure predictable and satisfactory performance for end users. In prior work, we have proposed a cross-layer approach called Shaper [3, 4] that uses TCP and a central router rather(More)
It is well known that competition between 802.11 wireless flows can lead to severe unfairness problems. In this paper we show that certain flows can be denied from their fair share of network access for long periods of time due toinequitable channel conditions. We argue that this unfairness problem is likely to get worse as the use of wireless in terms of(More)
A proliferation of compact representation schemes have been been proposed for various classes of games, along with efficient computations of solution concepts on such representations. The two main schemes have been Graphical games [7] and Multi-agent Influence Diagrams [14]. However, various other representations exist such as Game Networks [13] and(More)
In this paper we present an implementation of the Rao-Blackwellised particle filtering (RBPF) with one step look-ahead and apply the algorithm within the domain of agent navigation. Specifically we tackle the simultaneous localization and mapping problem (SLAM), which describes how a agent must concurrently attempt to determine its location and generate a(More)
