Application Development For ZigBee Wireless Networking
Drew Gislason, San Juan Software
This presentation explains how the ZigBee networking protocol
extends the capabilities of 802.15.4 radios to include longer
range and higher reliability through multi-hop mesh networking,
high security through AES 128-bit encryption, device interoperability
through application specific profiles, and long battery life
(up to years) through a power centric protocol.
An overview is given on how to develop applications
for a ZigBee networked environment, including understanding
what hardware and tools are required, and how a ZigBee application
looks in source code form.

Implementing ZigBee Networks in Industrial Sensing Applications
Tim Cutler, Cirronet
Most everyone has heard of ZigBee and the promise it holds for Industrial Sensing and Monitoring applications. But exactly how does one implement a ZigBee network in an existing plant with existing sensors and industrial automation systems? This presentation explains ZigBee from an industrial sensing perspective including how to connect sensors to ZigBee devices, how to get data out of the ZigBee network and how to integrate this data into existing monitoring and control programs.

Building Low Power into Wireless Sensor Networks Using ZigBee
Jon Adams, Freescale
Wireless sensor networks are ideal for home and industrial applications such as security and lighting. However, traditional wireless sensors consume a significant amount of battery power requiring a very large battery or frequent replacing - either of which make the cost too much for most settings. ZigBee is a low cost, low power solution that is emerging to meet this challenge. While battery life is ultimately a function of battery type, capacity and end-user application, the ZigBee protocol was designed from the ground up to enable very long life battery applications. Battery lifetimes are increased from a few months to many years as a result of a host of system power-saving modes and battery-optimized network parameters, such as a selection of beacon intervals, guaranteed time slots, and enablement/disablement options, making it ideal for wireless sensor networks. Sensors utilizing ZigBee technology can work together wirelessly in a star, mesh, or cluster tree network enabling the end installer to offer sensor network coverage across an entire office or building complex with the convenience and reduced installation expense achieved through wireless technology.

Sensor Networking With ZigBee: PLATFORM Independence For True Interoperability
Srini Krishnamurthy, Airbee Wireless, Inc.
The need for a new wireless network standard to meet the needs of sensors and control devices adequately has lead to the development of a new global standard called ZigBee. Other standards such as Bluetooth and WLAN are now considered to be unsuitable for low power applications as they deal with complex and high power consuming RF-ICs and protocols. The suitability of ZigBee for cost-effective, reliable, low-power wireless applications has given rise to sensor networking for monitoring and control applications. Thus was born the ZigBee Alliance, a consortium of well over 100 companies that looked at what the short range, low power radio frequency (RF) 802.14.5 could do and built upon it the mesh networking standard to make devices and networks completely interoperable between multiple vendors.

De-mystifying the building of ZigBee applications
Zachary Smith, Ember Corporation
This presentation aims to provide a high-level "punch list" of some of the less understood application considerations developers face before designing their ZigBee solutions, including issues such as network topologies, interoperability options, security levels, platform differences, and development environments. Attendees will come away with a better understanding of how to approach the design of ZigBee applications, which questions to consider, which approaches to weigh, and which vendor features to scrutinize.

Thinking Beyond the Sensor Network
Pat Kinney, Kinney Consulting
To unlock the full potential of sensor networks a method of communication with Industrial LANs and the Internet is needed. In this respect wireless sensor networks are no different than wired sensor networks. A Gateway is a device that allows disparate networks to exchange information. Gateways convert the wireless protocols and sensor data into the myriad of formats necessary for industrial, commercial, and residential systems. Examples of these formats include BACnet and LonWorks for building systems, SCADA and Modbus for industrial networks, and of course HTML and XML for Internet applications.
Gateways allow wireless sensor networks to use those protocols well suited for the harsh RF environment as well as battery powered applications and allow them to be integrated into existing applications.
This presentation explains the merits of gateways and bridges and the capabilities that they provide to the system designer and end user.
