Transparent coordinator failure recovery for ZigBee networks

ZigBee is a network stack requiring only low power consumption, that is used in different application areas. The 2003 ZigBee implementation has flaws when the coordinator node fails, because it represents a single point of failure. This paper presents a new approach to overcome this pitfall. The solution is transparent for communicating end nodes, easy to use, and supports all ZigBee features. It uses a backup solution for coordinator nodes that is implemented at the application level. The approach has been implemented and tested in a real-life setup. In addition to that, the paper introduces a model of a more complex configuration and presents simulation results for the proposed approach.
