Home networking with zig bee

  1. 1. Prepared by : Eyad R. ManaaSupervised by : Eng. Mahmoud El-Aff The Islamic University of Gaza Computer engineering Department 1 December 23,2010
  2. 2. Outlines Introduction What is ZigBee ? ZigBee Features What does ZigBee do? ZigBee Advantages ZigBee in Homes How a ZigBee Network Works ZigBee Network Configuration Summary 2
  3. 3. Introduction Wireless technologies is already an integral partof our lives. Bluetooth provides connectivity in a short range ofdevices. WiFi is used for local area networks, thus it isconsumes high power. WiMAX provides wide area networking, thus itneeds more power and high cost. But we need in our homes technology thatconsumes low power and low cost and low data rate. 3

  12. 12.  Supports large number of nodes Easy to deploy Multiple vendors Very long battery life Secure (128 bit encryption) Reliable and self healing Low cost Can be used globally (2.4GHz) 12
  13. 13. ZigBee Coordinator (ZC) – One required for each ZB network. – Initiates network formation.ZigBee Router (ZR) – Participates in multihop routing of messages.ZigBee End Device (ZED) – Does not allow association or routing. – Enables very low cost solutions 13
  14. 14.  ZigBee’s Network layer supports three networking topologies: star, mesh, and cluster tree. 14
