Improving ZigBee Networks Robustness with Multi-channel Capability

  title={Improving ZigBee Networks Robustness with Multi-channel Capability},
  author={X. Cui},
Based on IEEE 802.15.4, ZigBee is developed for low-power and low-data-rate wireless communication and it is building up remarkable position for wireless sensor network (WSN). As ZigBee is using the 2.4GHz Industrial, Scientific, and Medical (ISM) unlicensed frequency band, coexistence issues arise as there are also other wireless technologies sharing the same band, such as 802.11b/g WiFi, Bluetooth, cordless phones and even microwave ovens. Due to the low transmission power, ZigBee is… Expand
IEEE 802.15.4 Beaconing Strategy and the Coexistence Problem in ISM Band
Simulation results show that by applying the beacon corruption recovery scheme (BCRS), an 802.15.4 network experiences a less fragmented accesses to the medium and better fulfills real-time bidirectional flow of monitoring information. Expand

An interference analysis model is suggested to obtain an estimate of Packet Error Rate (PER) of a ZigBee network and the measured PLR matches the estimated PER. Expand
A Coexistence Model of IEEE 802.15.4 and IEEE 802.11b/g
A coexistence model is presented, which exposes the interactive behavior between these two standards and therefore accurately explains their coexistence performance, and introduces a concept of coexistence range, by extending the concept of sensing and interference ranges across different wireless standards.
