Abstract
Based on IEEE 802.15.4 Low Rate-Wireless Personal Area Network (LR-WPAN) standard, the Zigbee standard has been proposed to interconnect simple, low rate and battery powered wireless devices. The deployment of Zigbee network is expected to facilitate numerous applications such as Home-appliance networks, home healthcare, medical monitoring and environmental sensors. An effective routing scheme is more important for Zigbee mesh networks. In order to achieve effective routing in Zigbee Mesh networks, a Zigbee protocol module is realized using NS-2. The suitable routing for different data services in the Zigbee application layer and a best routing strategy for Zigbee mesh network are proposed. The simulation shows the selection of suitable routing for continuous data services and for bursting data services in the Zigbee application layer and the comparison of three routing strategies namely ERD (All packets Enable Route Discovery), SRD (All packets Suppress Route Discovery) and BOS (routing Based on Data Services) in the aspects of Efficiency and Overhead.
Highlights
Zigbee is an emerging worldwide standard for Wireless Personal Area Networks (WPAN)
Tree and mesh topologies, self-forming and self-healing as well as more than 65000 address spaces; the network can be extended in terms of size and coverage area
The hierarchical routing algorithm depends on the topology and a distributed addressing scheme of Zigbee networks
Summary
Zigbee is an emerging worldwide standard for Wireless Personal Area Networks (WPAN). Under the main goal to provide low-power, cost effective, flexible, reliable and scalable wireless products Zigbee Alliance has been developing and standardizing the Zigbee network. Based on IEEE 802.15.4 [1], Zigbee defines three types of devices. They are Zigbee Coordinator, Zigbee Router and Zigbee End device. Tree and mesh topologies, self-forming and self-healing as well as more than 65000 address spaces; the network can be extended in terms of size and coverage area. The tree network uses a hierarchical tree routing mechanism. The mesh network uses the mixed routing method combined with Z-AODV and hierarchical tree routing
