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)

—Urban environments are notorious for high levels of noise and interference, particularly in their unlicensed radio bands. The interference patterns visible on a given channel depend on the particular devices competing for the spectrum. Meanwhile, the modern transceivers incorporated into wireless sensor network (WSN) nodes have the ability to measure the(More)
