A Review of the Challenges in the Implementation of Next-Generation ZigBee Networking

AbstractOne of the key challenges in the implementation of ZigBee networks is the development of algorithms which provide autonomous meshing of beacons with minimal or no interference. This feature is out of the scope of current ZigBee capabilities. The energy and bandwidth constraints and the potential large-scale deployment pose challenges in efficient resource allocation and sensor management. In this review paper, we will focus on the problems which hinder the reliable and low-latency operation of deeply-embedded wireless sensor networks. We will also analyze the proposed solutions which play a key role in bolstering ZigBee as the true mediator in making the current scenario of wireless sensor networks (WSN) networking more reliable and thus paving the way for meeting the challenges and requirements demanded by next-generation ZigBee networks. The Review paper has been divided into two parts. In the first part, we briefly introduce the beaconing mechanism of IEEE 802.15.4 and analyze it from the point...
