....This is due to the location criterion that may suggest a new set of potential provider agents to consider. We recall that the identification of a provider agent for a service depends on the current position of the provider agent of the direct predecessor service. 6 Related work and conclusion In [3], Chakraborty et al. have introduced a reactive service composition architecture for pervasive computing environments. The architecture consists of five layers: network, service discovery, service composition, service execution, and application. While reviewing Chakraborty et al. s work, we were ....

....by the user. In this case, the user may indicate the kind of Web pages she will be willing to access (e.g. subject of interest, URI, s) The information is then exploited, possibly in combination with the user s pro file, to prefetch a number of pages. Similar to our solution, the one of [3] in the area of service discovery and composition or [19] in the area of databases use a decentralized model in an ad hoc environment. Complementing proxy solutions with ad hoc based ones will allow for both enhanced connectivity and Web access at low cost. In that context, the caches of the ....

....meeting platform has also allowed user delegates to undertake their operations without being concerned with the scarcity of the computing resources that feature mobile devices. Chakraborty et al. have also introduced a reactive service composition architecture for pervasive computing environments [7]. The architecture consists of five layers: network, service discovery, service composition, service execution, and application. While reviewing their work, we were interested in the service execution layer. During the execution of services, this layer might want to optimize the bandwidth required ....

....environment is unknown. In order to satisfy user requests, applications on a device discover services or information on other devices in their vicinity[1] In some situations, information or services that are available on multiple devices are composed together before being presented to the user[7]. Users rarely query the system in the traditional database sense, but often declaratively specify things they are interested in. The system in turn needs to query data sources, most of which are volatile in as much the vicinity of a device keeps changing with movement thus changing available data ....
.... which means that devices in the vicinity cannot by default be assumed to be trustworthy[19] The eBiquity group (http: research.ebiquity.org) at the University of Maryland Baltimore County, is involved in the design, development and evaluation of a framework that 3 addresses these issues[7], 1] 32] 19] This paper focuses on the security challenges and our proposed solution. We seek to address security issues in pervasive computing environments through the use of agent methodologies and distributed trust. We present Vigil as the security infrastructure for such pervasive ....
