....connections using a version of Snoop TCP [2] Loon and Bharghavan used user profile based prefetching cooperating with a cache, in a system with both a local and remote proxy, and found that Web surfing waiting times can be reduced by a factor of 3 7 depending upon the time of day. According to [22], using remote processing to reduce the number of connections across a wireless link when browsing pages with images can reduce response time significantly as the number of images in a page increases. For a page with 16 images, the average waiting time is reduced by approximately 30 . They also ....

....be interesting to get results about the performance of this kind of systems to exactly knowhow costly this process is. A new technology, mobile agents [17] can aid to reduce the network connection time. We recall in this paper a software retrieval service [11] belonging to the ANTARCTICA system [20] which has been designed using mobile agents. The aim of this service is to propose an alternative method to the currentweb based software retrieval systems, called in this article Tucows like systems. The ANTARCTICA system has been designed to be used in wireless communication environments ....

Agents are executed in contexts denominated places [10] Mobile agents can travel from one place to another. The proposed service incorporates one place on the user computer called the User place, and other three places situated on the GSN, called the Software Acquisition place, the Software ....

....mobile environments. A decentralized solution is proposed using mobile agents, which also help in the optimization of the communication effort. 1. Introduction Mobile computing introduces new challenges for data management [7, 8] In this paper we present a data service of the ANTARCTICA system [12] whose goal is the processing of location dependent queries, i.e. queries for which the answer depends on location of objects. We deal with contexts where not only the user issuing the query can change her his position, but the objects involved in the query can move as well. A sample ....

....technology is used in the system implementation and therefore there exist several agents in the system each one specialized in a different task. The proposed implementation offers flexibility and adaptability. The system proposed in this paper takes part of a more global system called ANTARCTICA [11] which main goal is to offer a set of data services that enhance the capabilities of mobile computers and so, to offer new possibilities to mobile users. Among the services that the ANTARCTICA system offers we can mention: an efficient access to web pages and to data repositories through SQL, a ....

A preliminary version appears in [VGGI98] a mobile middleware that supports applications for mobile users. In [PSP00] a statistical analysis appears that demonstrates the interest of using mobile agents for web database access. This last group of works is the closest to ours. However two main features di erentiate our proposal ....
