ZigBee Wireless Networks and Transceivers by Shahin Farahani, PhD, System Engineer, Freescale Semiconductor

ZigBee is a short-range wireless networking standard backed by such industry leaders as Motorola, Texas Instruments, Philips, Samsung, Siemens, Freescale, etc. It supports mesh networking, each node can transmit and receive data, offers high security and robustness, and is being rapidly adopted in industrial, control/monitoring, and medical applications. This book will explain the ZigBee protocol, discuss the design of ZigBee hardware, and describe how to design and implement ZigBee networks. The book has a dedicated website for the latest technical updates, ZigBee networking calculators, and additional materials. Dr. Farahani is a ZigBee system engineer for Freescale semiconductors Inc. The book comes with a dedicated website that contains additional resources and calculators: http://www.learnZigBee.com Table of Contents Chapter 1: ZigBee? Basics Chapter 2: ZigBee? / IEEE 802.15.4 Networking Examples Chapter 3: ZigBee? / IEEE 802.15.4 Protocol Layers Chapter 4: Transceiver Requirements Chapter 5: RF Propagation, Antennas, and Regulatory Requirements Chapter 6: Battery Life Analysis Chapter 7: Location Estimating Using ZigBee? Chapter 8: ZigBee? Coexistence Chapter 9: Related Technologies Appendices

Audience:
This is a complete guide to the ZigBee wireless networking standard, transceiver performance requirements, location estimation, and power reduction methods.

GTS allocation scheme using knapsack problem algorithm

March 25, 2011

Goal :

  1. To improve the GTS allocation scheme in the IEEE 802.15.4 based MAC when used for a large number of medical and physical sensor devices deployed in a WiBaSe-Net

Note :

  1. Wireless body area sensor network (WiBaSe-Net) is an emerging technology that can be used in medical, entertainment, and fitness applications.
  2. In a WiBaSe-Net, several wearable or implanted sensor devices, for instance electro-cardiogram (ECG) sensor, blood pressure sensor, temperature sensor, respiratory sensor, pulse oximeter, and accelerometer are deployed throughout the body. A body controller unit (BCU) collects data from the sensor devices and send it to the medical center.
  3. IEEE 802.1.54 supports not only contention based access mechanism, but also supports guaranteed time slot (GTS) scheme under beacon-enabled mode for delay-sensitive applications.

Castalia Simulator

November 12, 2010

Mainan baru buat belajar GTS IEEE 802.15.4 or Wireless Body Area Network (WBAN)   🙂

Castalia is a simulator for Wireless Sensor Networks (WSN), Body Area Networks (BAN) and generally networks of low-power embedded devices. It is based on the OMNeT++ platform. It offers a complete new way to run simulations and view the results. It has a brand new radio module. Implemented GTS mode in 802.15.4 MAC. It implements the Baseline MAC for Body Area Networks, proposed by the IEEE 802.15 Task Group 6.
