EWSN 2016

The  International Conference on Embedded Wireless Systems and Networks (EWSN) is a highly selective single-track international conference focussing on premier research results at the intersection of embedded systems and wireless networking  – an area of highest relevance for visionary technologies such as the Internet of Things or Cyber-Physical Systems and application domains such as Smart Production, Smart Cities, or Connected Cars.

The featured topic of the 2016 edition of EWSN is “Dependability” and we specifically welcome contributions that aim at making networked embedded systems more reliable, predictable, safe, and secure in order to enable critical applications that require guaranteed performance.

EWSN 2016 will also host a competition on dependability as well as workshops in emerging areas, one of these workshops will focus on novel embedded communication paradigms.

EWSN has been established in 2004 as the European Conference on Wireless Sensor Networks and has been held since then in European cities. For the 2016 edition, the scope still includes Wireless Sensor Networks, but has been broadened to all topics at the intersection of embedded systems and wireless networks.

850 Million IEEE 802.15.4 chipsets to ship in 2016

The IEEE 802.15.4 IC market, often referred to as wireless sensor networks (WSN), will expand to over 850 million units per annum by 2016, experiencing a compound annual growth rate of over 60% from 2010 to 2016.
While growth is led by advanced metering infrastructure (AMI) equipment, significant uptake is expected in home automation, home entertainment, medical, and others, says ABI Research.

ZigBee is the most widely-used IEEE 802.15.4 technology, accounting for 40% of total shipments in 2012 and growing to over 50% by 2015. Current deployments and growth are being driven by the ZigBee Alliance, the industry body now comprising over 400 members including IC suppliers such as Freescale, Intel, Marvell, NXP, STMicroelectronics, and Texas Instruments.

“Many IC suppliers have seen the potential of ZigBee and other 802.15.4 technologies and are helping drive new application solutions including the latest ZigBee Light Link standard,” says Peter Cooney. “No doubt these vendors see the potential of adding ZigBee to their arsenal of wireless connectivity technologies alongside Bluetooth, Wi-Fi, NFC, and others.”

As ZigBee grows in its key markets and expands into new areas it will see increasing competition as other technologies also continue to develop. One technology that will compete with ZigBee, particularly in the home environment, is Bluetooth. “ZigBee offers many advantages for smart home applications including large network sizes, low power consumption, and low cost solutions, however the ubiquity of Bluetooth in the smartphone and consumer desire to use this device as the home hub/controller will drive use of Bluetooth Smart and Smart Ready devices in the smart home environment, making it a strong competitor to ZigBee in this space,” comments Cooney.

What’s Driving The Success Of IEEE 802.15.4 Radios?

Since its 2003 release, the IEEE 802.15.4 radio has become hugely popular for wireless sensor and actuator networks (WSANs), and it is the underlying radio standard for protocols such as ZigBee, 6LoWPAN, and WirelessHART. This growth can be attributed to its availability as an inexpensive standard IC. It’s also sophisticated yet reasonably easy to use.

The IEEE 802.15.4 radio is a short-range, multichannel, spread-spectrum radio designed to support large, low-power, low-data-rate mesh networks. The standard and ZigBee are often, and improperly, considered synonyms of one another. Therefore, it’s important to understand the clear separation of functions implemented in the radio from those managed in the upper protocol layers.

The 802.15.14 standard only specifies the lowest two layers of the protocol stack—the physical layer (PHY) and medium access control (MAC) layer. The upper layers of the protocol are separately defined by various interests according to their specific application needs. Of these, the largest and best known is the ZigBee Alliance. However, myriad proprietary protocols are also in use today, and they all rely on 802.15.4 as their underlying radio standard.

Awarepoint Spreads Awareness for Wireless Sensor Networks in Hospitals

ZigBee-based wireless sensor networks are ideal for use in acute care hospitals and beyond, noted Matt Perkins, chief technology officer and senior vice president of engineering at Awarepoint, a provider of ZigBee-based real-time location solutions (RTLS) for healthcare.

Perkins recently addressed attendees about real-time location, condition sensing and ZigBee-based wireless sensor networks for use in acute care hospitals and beyond at the 2010 Mobile Health Expo.

Those attending Awarepoint’s ‘Transformational Services Track’ breakout session will get useful insight about Real-time Location System (RTLS) applications in hospitals. Perkins will describe in detail, at the session, the benefits of knowing location, status and movement of assets, patients, healthcare workers, visitors, vendors and any other resources or people within the hospital infrastructure.

In addition, the session will also cover how ZigBee-based wireless sensor networks offer a promising solution for a variety of healthcare applications beyond acute care hospitals.

The session was held at the Las Vegas Caesars Palace Convention Center, 3570 Las Vegas Blvd South, Las Vegas, NV 89109, during the Mobile Health Expo, Oct. 19 to Oct. 21.

Prior to working at Awarepoint, Matt Perkins worked 10 years at Motorola as technical director of the Things-to-Things Research Center. At Motorola, Perkins was responsible for aligning business partnerships with technology roadmaps, directing strategic joint research related to distributed sensor networks and leading the development of Motorola’s Asset Tracking and Smart Energy technologies.

In addition to leading research on radio-location technologies and wireless sensor network protocol development, Perkins contributed to the IEEE 802.15.4 and IEEE 802.15.3 standards and actively participates in the ZigBee Alliance.

Open-ZB website to Reach 100k Visits

The open-ZB website provides open source tools for IEEE 802.15.4 and ZigBee, the most widespread technologies for Wireless Sensor Networks. Notably, it has reached over 100 000 visits and 6000 downloads of the toolset from around the world. This represents 4-5 downloads in average per day, almost 4 years after the first release (November 2006).

Since early 2009, the open-ZB research team has triggered the creation of the TinyOS 15.4 and ZigBee Working Groups. The aim is to provide 15.4 and ZigBee implementations that build on top of the WSN research community efforts and empower users to learn, modify and reuse the code at free will.Further improvements include QoS add-ons, traffic differentiation and communication reliability among others. The work have been mainly supported by the CONET Network of Excellence, within the COTS4QoS research cluster.

WSN IC shipments to reach 645 million in 2015

Worldwide wireless sensor networks shipments to reach 645 million in 2015, at a compound annual growth rate (CAGR) of 99.6%, compared to approximately 10 million chipsets in 2009, according to ABI Research.

The research firm said that 802.15.4 chipset shipments in 2009 were down by 30% compared to previous year.

However, it has been revealed that there is an increasing shift towards 802.15.4 based shipments compared to the proprietary offerings.

ABI research principal analyst Jonathan Collins said that because they are based on emerging technology, wireless sensor network adoption suffered during 2009 as pilots and early projects were scaled back or put on hold.

“However, 2010 has seen a significant rebound and strong shipment growth,” Collins said.
