However, home devices often carry a large amount of real physical world information, which may result information leakage problems. In this paper, reveal privacy security issues existing ZigBee-based networks, we design analysis system based on ZigBee-encrypted traffic, called ZPA. ZPA can extract d...

Wireless networking technologies are being implemented in quite a few devices including phones, mobiles, mp3 players etc. The performance of these technologies varies from one to another. The aim of this paper is to analyze the performances of two different low power consumption technologies: Bluetooth and Zigbee. The performance parameters include data coding efficiency and transmission rate. ...

Most ZigBee sensor networks to date make use of nodes with limited processing, communication, and energy capabilities. Energy consumption is of great importance in wireless sensor applications as their nodes are commonly battery-driven. Once ZigBee nodes are deployed outdoors, limited power may make a sensor network useless before its purpose is complete. At present, there are two strategies fo...
