PRAVTA—A Light-Weight WAP Awareness Client
نویسنده
چکیده
Despite huge progress in information and communication technology it is often difficult to spontaneously contact persons who are at other locations. This is often due to the fact that important information about the persons at the other sites is missing. Users need to know if the potential communication or cooperation partners are present in the system, if they are available, how busy they are, and so forth. Furthermore, users need this information independently of their current location and adapted to their current context. In this paper we introduce the PRAVTA prototype that provides users with awareness about presence, availability, and tasks of other users anytime and anyplace.

An Efficient Load Balancing Strategy for Scalable WAP Gateways
In this paper, we propose a load balancing strategy that has the following features: (1) estimating the potential load of real gateways with low computation and no communication overhead, (2) asynchronous alarm sent when the utilization of a real gateway exceeds a critical threshold, and (3) WAP-awareness. We also propose a scalable WAP gateway (SWG) that consists of a WAP dispatcher and a clus...
متن کاملEnabling Mobile WAP Gateways using Mobile IP
The Wireless Application Protocol (WAP) is a protocol stack with a focus on wireless environments designed to work optimally with all wireless bearers. However, WAP does not provide any considerations for any of its architectural components (Client, Server or Gateway) to be roaming between network operators and Internet administrative domains. In this study it is experimentally shown that mobil...
متن کاملThe Share-Loc Project: a WAP-based maritime location system
Automatic Identification Systems (AIS) currently used to detect and warn about possible maritime navigation collisions are a suitable solution for well equipped ships, but are unfortunately quite expensive and difficult to maintain for small ships and pleasure boats. The Share-Loc project purpose is to design and implement an alternative maritime navigation system for small ships and boats. The...
متن کاملPeripheral Awareness in a Theatre of Work
Knowledge workers typically work at a number of different places and cooperate with local or remote colleagues. At the same time they work in both the physical world with physical artefacts and in the electronic world with electronic artefacts. In all these different settings they need information about their coworkers and about shared artefact as a basis for efficient work that adequately cont...
متن کاملIntegrated Transport Layer Security: End-to-End Security Model between WTLS and TLS
WAP is a set of protocols that optimizes standard TCP/IP/HTTP/HTML protocols, for use under the low bandwidth, high latency conditions often found in wireless networks. But, end-to-end security is not supported unless a WAP gateway is operated by the content provider. We propose ITLS mechanism to solve the WAP security problem. The goal of ITLS is to prohibit the WAP gateway from having the pla...
