Embodiments of the invention employ a distributed algorithm to enable sensor nodes in a sensor network to adaptively self-configure into sensor clusters to provide a desired higher-level functionality.

Methodology to program sensors into collaborative sensing groups

A software system with a two tier arrangement for threads support that enhances the adaptability of a virtual machine to differing platforms. The software system includes a virtual machine with a threads interface layer having a set of methods that provide thread support in the virtual machine according to a standard threads interface associated with the virtual machine. The software system includes a native threads interface layer that provides a set of methods that adapt the methods of the threads interface layer to a platform which underlies the software system. The native threads interface layer shields the virtual machine from the particulars of the underlying operating system while the threads interface layer provides a stable interface for application programs and other tasks that benefit from thread support in the virtual machine.

Two tier arrangement for threads support in a virtual machine

A system for creating a custom environment for executing application programs in a target device. The system broadens the applicability of software environments like Java by providing custom pre-loaded classes for application programs and by customizing the procedures for class loading to the available resources in the target device. The system includes tools for generating a pre-load class list that specifies a set of classes needed to support the application program. The tools build the custom environment including a set of code for a virtual machine and a set of code for each of a set of pre-loaded classes specified in the pre-load class list. The virtual machine loads classes from the pre-loaded classes, a file system class library, and/or a networked class library using widely available network protocols.
