Caching frequently accessed data items on the mobile client is an effective technique to
improve the system performance in mobile environment. Due to cache size limitations, the …

We consider a basic scenario in wireless data access: a number of mobile clients are
interested in a set of data items kept at a common server. Each client independently sends …

Caching frequently accessed data items on the client side is an effective technique to
improve the system performance in mobile environment. Due to cache size limitations, the …

Greater network latencies and swelling amount of data provide sound reason for semantic
caching for multi-db environment. Properly implemented Semantic caches, provide better …

While the traditional data shipping systems use physical information to organize data, a
newer data caching technique maintains both associated answers (data items) of previous …

Broadcasting is the natural method of propagating information in wireless links, which
guarantees scalability in the case of bulk data transfers. It is particularly attractive for …

We present an experiment relative to the use of Bluetooth wireless technology to provide
network support for midlet applications accessing Web services. We refer to the most …

In a mobile wireless environment, the latency (time-delay) observed by a user before s/he
receives up-to-date information may be high because of the limited available bandwidth. An …

A location dependent query (LDQ) result set is valid only in a specific region called the
validity region (VR). While limiting the validity of a particular result set to a given area, the VR …
