A Survey on Routing Protocols in ZigBee Network

The IEEE 802.15.4 is a new standard defined for LR-WPAN which provides a low cost and very less complicated solution. The targeted applications are wireless sensors networks (WSN), interactive toys, home automation and remote controls. ZigBee is one of the newest technologies developed by ZigBee Alliance, enabling Wireless Personal Area works (WPAN). ZigBee is the name of a specification for a suite of high level communication protocols using small, low-power digital radios based on the IEEE 802.15.4 standard. This paper includes the introduction to Network Nodes and Topology supported by IEEE 802.15.4/ZigBee Standard, also we have discussed the standard routing protocols used in the ZigBee standard. We have done a survey to figure out the variousproposed modified algorithms based on the standard routing protocols, which have better network performance in terms of Packet delivery ratio, Hop delay, Optimal path length, Average end to end delay, Packet loss (%), Network Lifetime, Throughput, Normalized Routing Overhead etc.as compare to standard routing algorithms used in ZigBee network.
