Here’s a great talk from Kris Pister Prof. EECS, UC Berkeley, Founder & CTO, Dust Networks. It shows some results from years of experimentation on how to build reliable nets out of nasty unreliable RF channels.
Half of this talk, at CITRIS, is devoted to break down TSMP, a MAC/Network protocol that implements time, space and frequency diversity to provide five 9 reliability communications in a mesh network of sensor nodes.
While some false-starts have limited deployments to date, it seems the dust begins to settle: proven low power solutions for difficult RF environments with multi path interference, thus leading to industry-strength solutions and no site survey installations among different application spaces.
Where are they heading today? Toward a mote on a standard CMOS SoC (~4 mm^2) expected for 2009 and 10 years of battery life out of a coin cell, but then photo-voltaic also potentially embedded in the chip..

The large increase in aging population has a strong negative effect on the cost and quality of healthcare.
The delivery of clinical care through assistive monitoring represents a cost-effective solution to this problem.
The NOMADIS research lab developed an Assisted Living system, called Safe and INDependent LIving (SINDI) focused on the intelligent use of technology to improve the quality of life of people who live mainly at home.
SINDI has three components:
- a wireless sensor network that continuously evaluate the state of the elderly,
- a set-top box that handles TV, communication with the outside world and an agenda including the intake of drugs, and
- a logic-based reasoning engine that supports effective conflict resolution and it is able not only to trace general habits of a patient (walking ability, quality of sleep, movements within the house) in an unobtrusive way, but also to understand dependencies between behaviors and patient’s well-being, based on a hierarchical model of health.
The sensor network of SINDI has a large number of sensors both in fixed locations and on the patient’s body.
The network is used both for data collection and for localization. Such a network requires a clever management of routing and power consumption. Moreover, the system is able to understand the evolution of patient’s health state and prevent situations that could be potentially critical, before the emergency arises.

Cisco and Nivis this week demonstrated an operational wireless IP mesh network using the low-power IPv6 protocol, dubbed 6LoWPAN.
Using Nivis wireless sensors and routers, the demonstration network linked a parking meter with several streetlights, a sensor ring in a parking space, and what was described as a Cisco cell phone. The arrangement was used to communicate to the driver that a parking space was available, and in another instance that the meter had expired. The same system could be used to alert security details to turn on parking garage lights, or provide traffic meter staff with information about expired or inoperable meters.

Sentilla’s Pervasive Computing Platform is now said to be available under a variety options. Customers and integrators may license the software directly from Sentilla as part of their own solution, or may purchase computer modules that combine software and hardware in a compact, scalable device suitable for an OEM.
For those wishing to get started right away, Sentilla’s platform is also available as a Development Kit, which includes the Java Powered(TM) software pre-installed on eight low-power wireless computers, an Eclipse-based IDE, server software for management and integration, and a gateway device to connect the pervasive network to a PC.

The SOCRADES project is a European Commission co-funded project featuring major industrial players of the automation and business domains. SOCRADES focuses on perception and control systems in intelligent environments, which are enhanced with system intelligence achieved by co-operation of smart embedded devices pursuing common goals.

Wireless sensor networks are not being fully utilized in commercial markets due to the lack of a ‘killer application’ to drive interest, a Plextek led report for U.K. communications industry regulator Ofcom has concluded. The 10-month study was commissioned to examine technology developments in wireless sensor networks, along with likely market growth scenarios and what the spectrum implications would be.
The report suggests WSNs may begin to become more widely deployed over the next three to five years, with systems continuing to adopt existing licence-free bands including 13.56MHz, 433MHz, 868MHz and 2.4GHz. The main issue for WSNs will be the crowding of bands, especially 2.4GHz with the increasing use of Wi-Fi.

Banner Engineering has introduced M-GAGE Wireless Sensor Node for vehicle sensing using its new SureCross Wireless Network.
The specially optimised M-GAGE wireless sensor is encapsulated in a rugged, IP67 SureCross Node enclosure and accompanied by a long-lasting FlexPower battery.
The battery supplies power for both sensing and wireless connectivity up to 10 years.
The M-GAGE wireless sensor offers greater durability and reliability than inductive loops and is less costly to install and maintain. Simple in-ground installation requires no major excavation and provides quick and easy access for battery replacement when required.
