We are pleased to announce the availability of several new multi-hop
communication modules for TinyOS. The released code can be found under
contrib/hsn in CVS.
This implementation is part of Intel's Heterogeneous Sensor Networking
(HSN) and Sensor Gateway projects. The release includes two ad hoc
routing protocol implementations and several other modules useful for
creating a multi-hop sensor network. Following is a list of features
included in this release:
- DSDV: A single-destination implementation of the
Destination-Sequenced
Distance-Vector algorithm. Our implementation includes two metric
modules -- hop count and predicted end-to-end success rate -- and is
extensible to support other metrics.
- TinyAODV: The TinyAODV stack implements a modified version of Ad-Hoc
On
Demand Distance Vector (AODV) routing algorithm. Various
simplifications
have been made in order to the implement the AODV protocol in a very
small footprint. It supports multiple destinations and currently
uses
only one metric, i.e. hop count to route packets.
- Flood: A mechanism for flooding packets into a network of nodes.
- Neighborhood Monitor: This family of modules tracks a list of recent
neighbors, the age of each neighbor (time since last packet), the
reliability of the inbound and/or outbound link to each neighbor,
and
other per-neighbor statistics.
- TinyDB Integration Shim: This module allows TinyDB to utilize our
DSDV
routing module.
- Settings control: This module allows the behavior of the above code
modules to be dynamically controlled. It also allows the user to
monitor the settings of individual network nodes. This mechanism is
easily extensible to support additional modules. A sample TCL/TK
GUI
is provided to generate and inject control packets into a network.
- TraceRoute: This simple traceroute application runs on top of DSDV
to
identify the routes taken by packets as they travel through the
network.
Instructions for installation and use of these modules are available in
CVS.
The current release has only been tested on Mica motes. Future releases
will support Mica2 and will include additional capabilities.
