Abstract
Recent technological and economic advances in wireless devices make it
feasible to deploy ad hoc networks of sensors and robots. As
the costs of the electronics drops, the cost of deployment is
increasingly dominated by the cost of control and interoperability
software.
It is therefore attractive to program such devices using relatively
high level languages and to consider how a middleware software stack
can provide maximal code reuse and interoperability.
We describe our work in developing a software control fabric based on
a Java middleware. We have used WaveLAN technologies to prototype our
system and are actively working on Bluetooth interoperability for
deploying groups of cooperating mobile robots.
We discuss the key wireless issue of disconnection and how our high
level middleware provides a framework for experimentation with
different protocols and distributed algorithms.
Keywords: wireless; mobile computing; middleware; sensors;
autonomous robots; remote sensing; Bluetooth.
