Interactive Host-Assisted Execution Framework for Wireless Sensor Nodes
Ahmad Abiri
Wireless programming of embedded systems is
gaining popularity in the industry, largely due to
the fact that many wireless, low power sensors
are often difficult to access once installed in
their target environment. However, embedded
systems development and maintenance still remains costly largely due the variety of hardware
platforms and the lack of standardized development and debugging infrastructures. Next generation development frameworks seek to resolve these problems by providing a unified,
wireless, and interactive development environment.
of compatibility with a variety of hardware platforms. We improve portability to different platforms by making the node side runtime system
completely driver based and highly modular.
This allows functionalities such as Job Scheduler to be available only on nodes which posses
the necessary resources. Furthermore, protocol
drivers provide support for a variety of nodes
and communication interfaces. Compiler and
Linker scripts simplify adding support for new
platforms and a python shell keeps the interactive programming functionalities of the original
EcoExec untouched.
EcoExec was a host-assisted execution framework, introduced in 2010, which showed that it
is possible to achieve these criteria by automating classical compile-link-flash procedures using a feature rich host while utilizing very small
node side footprint. However, the EcoExec
framework was limited to the EcoNode platform
and could not support large, complex sensor
networks.
Complex networks and large infrastructures are
handled by using URI addressing and a centralized database. A Node Access Manager monitors and synchronizes simultaneous client access by utilizing various node locking mechanisms.
The current project proposes a redesigned and
enhanced the EcoExec implementation that addresses some of these outstanding issues.
Perhaps, the most important concern is the lack
Node connectivity is also improved by allowing
nodes to connect to the host subsystem ondemand, and servicing various requests. Finally, the node runtime framework no longer requires a restart after code updates, allowing
certain valuable global memory data to be preserved between code updates.
