Abstract:
An increasing number of applications is being written for mobile
hosts, such as laptop computers, mobile phones, PDAs etc. These
applications are usually monolithic, featuring very limited
interoperability and context-awareness and are usually difficult
to deploy and update. Application engineers have to deal with a very
dynamic set of environments that these applications are in contact
with and it is becoming increasingly difficult to design an
application that will be able to cater to all the user's needs in
those environments. This new setting forces a shift from design-time
to run-time effort in developing software systems. To solve these
problems and to allow a new class of ubiquitous and adaptable
applications to be built, we have designed and implemented Satin, a
middleware system that allows the flexible use of logical mobility techniques
by applications running on mobile hosts which are connected to very
different networks. In this paper we describe our approach and show
how Satin can be used to deploy and update applications on mobile
devices easily and efficiently.
