Introduction

The IEEE 802.15.4 standard was completed in May 2003. The ZigBee specifications were ratified on 14 December 2004.The ZigBee Alliance announced public availability of Specification 1.0 on 13 June 2005. Much research is still going on with ZigBee.

Academic ResearchResearch in ZigBee is being conducted in different fields:
