ZigBee Technology
Abstract - ZigBee Technology is a progression in wireless technology. Wireless is not a new technology as wireless internet are already in use; yet Zigbee technology set a new aspect in wireless technology. ZigBee is a low-cost, low power, wireless mesh network standard. The low cost allows the technology to be widely deployed in wireless control and monitoring applications. Low power-usage allows longer life with smaller batteries. This paper gives an overview of the ZigBee Technology and covers an application of ZigBee as “a part of a power reduction mechanism”. Proposed design of standby power reduction has the host-agent structure and uses ZigBee protocol that utilizes IEEE 802.15.4 standard as radio layer for communication between agents and hosts.
Keywords- ZigBee, Wireless Personal Area Networking (WPAN), Control Mechanism.
BACKGROUND
ZigBee is a new low rate wireless network standard designed for automation and control network. ZigBee is an established set of specifications for wireless personal area networking (WPAN), i.e. digital radio connections between computers and related devices. WPAN Low Rate or ZigBee provides specifications for devices that have low data rates, consume very low power and are thus characterized by long battery life.
Typically, about 5-10% of residential electricity in most developed countries and a rising fraction in the developing countries are consumed as standby electricity. Altogether, standby power use is roughly responsible for 1% of global CO2 emissions.
ZigBee defines two layers of the OSI (Open Systems Interconnection) model: the Application Layer (APL) and the Network Layer (NWL). Each layer performs a specific set of services for the layer above. The different layers communicate through Service Access Points (SAP). ZigBee defines three types of devices:
1). ZigBee Coordinator (ZC)
2).ZigBee Router (ZR)
3).ZigBee End Device (ZED)
