MaxStream, a well-known manufacturer of components for wireless communication, has just added a product to its line with the quite fitting name XBee (pronounced exbee), which makes its own modest contribution to the already quite thick blanket of electrosmog

Self-Learning Routing for ZigBee Wireless Mesh Networks
FREE DOWNLOAD
ABSTRACT ZigBee is defined to support low-rate wireless per- sonal area networks (WPANs). It supports tree and mesh routing. Observing that both routing mechanisms have their pros and cons, this paper proposes a Self-Learning Routing (SLR) protocol, which inherits the low

Understanding the zigbee stack and application profiles
FREE DOWNLOAD
There are many emerging wireless standards. Some seem to overlap in the space that they occupy in the market. ZigBee fulfills a unique space in that it is short range (10-70 meters) and is designed specifically for low data rates. This design enables ZigBee to have
