Providing affordable, high-quality healthcare to the elderly while enabling them to live independently longer is of critical importance. In our Smart Condo project, we have deployed a wireless sensor network in an 850-square-foot condominium for assisted living. The sensor network records a variety of events and environmental parameters and feeds the(More)
Providing affordable, high-quality healthcare to the elderly while enabling them to live independently longer is of critical importance, as this is an increasing and expensive demographic to treat. Sensor-network technologies are essential to developing assisted living environments. In our Smart Condo project, we have deployed a sensor network with a(More)
The low-powered transmissions in a wireless sensor network (WSN) are highly susceptible to interference from external sources. Our work is a step towards enabling WSN devices to better understand the interference in their environment so that they can adapt to it and communicate more efficiently. We extend our previous work in which we collected received(More)
We describe our " holistic " platform for developing wireless ad hoc sensor networks and focus on its most representative and essential virtualization component: VUE 2 (the Virtual Underlay Emulation Engine). Its role is to provide a vehicle for the authoritative emulation of complete networked applications before physically deploying any wireless nodes.(More)

In the simple devices used for wireless sensor networks, the costs associated with a layered approach can be significant. Small-footprint operating systems have been developed by adopting non-traditional approaches to network abstractions while still aiming to simplify software development. In these approaches, some elements of modularity are valuable to(More)
