BLUETOOTH AND ZIGBEE: A NETWORK LAYER ARCHITECTURE GATEWAY

摘要

Deployment of Wireless Sensor Network (WSN) plays a key role in the efficient development of solutions for many domains like home automation, disaster management, healthcare, environment monitoring, etc. Improvement in technology has resulted in a major focus on smart and energy efficient buildings wherein one of the major concerns is efficient power management. On-line, "any place any time", monitoring of the power status of various equipment in large buildings using smartphones/tablets requires remote communication between local sensor networks and remote user which may be operating on diverse network protocols like ZigBee and Bluetooth. There is a need for an efficient Gateway for mediating communication between sensor networks, which work generally using IEEE 802.15.4 based ZigBee and the users, who normally use equipment with support for either IEEE 802.15.1 or IEEE 802.11. The architecture of an efficient Gateway between IEEE 802.15.4 & IEEE 802.15.1 is presented in this paper with details of the data flow mechanism between the Bluetooth and ZigBee gateway. The proposed gateway mechanism is capable of converting IEEE 802.15.4 protocol data to IEEE 802.15.1 protocol data and vice-versa and is flexible enough that it can be used in any network that has Bluetooth enabled facility at its sink node.
