VigilNet V1.3 [Project
Website]
VigilNet is one of the major efforts in the
sensor network community to build an integrated sensor network system for
surveillance missions. The focus of this effort is to acquire and verify
information about enemy capabilities and positions of hostile targets. Such
missions often involve a high element of risk for human personnel and
require a high degree of stealthiness. Hence, the ability to deploy unmanned
surveillance missions, by using wireless sensor networks, is of great
practical importance for the military. Because of the energy constraints of
sensor devices, such systems necessitate an energy-aware design to ensure
the longevity of surveillance missions.
VigilNet currently consists about 40,000
lines of NesC and Java code, running on XSM, Mica2 and Mica2dot platforms.
The complete system is designed to scale to at least 1000 XSM motes and
cover minimal 100,1000 square meters to ensure operational applicability.
EnviroTrack V1.0 [Project
Website]
EnviroTrack, as an object-based distributed
middleware system, raises the level of programming abstraction by providing
a convenient and powerful interface to the application developer geared
towards tracking the physical environment. It contains run-time mechanisms
that efficiently abstract groups of sensors by logical objects which
maintain aggregate environmental state. Such objects may be logically
attached to moving entities in the physical environment, in order to monitor
the state of the tracked entity. The EnviroTrack middleware library
implements a set of protocols that off-load from an application developer
the details of inter-object communication, object mobility, as well as the
maintenance of tracking objects and their state.
EnviroTrack 1.0 is built upon
TinyOS 1.1.0.
JIAJIA NT 2.0 [Project
Website]
A shared memory system with a
locked-based cache coherence protocol and A NUMA-like memory organization
scheme.
