Abstract :
The characteristics of low transmission power and narrow bandwidth make the IEEE 802.15.4 system vulnerable to external interference. The interference varies in time, frequency and is not able to be recognized since the modulation technology is normally different. As applications in the field of electrostatic detection require large-scale deployment, the traditional method of switching channel to avoid interference is difficult to achieve. This paper proposes an interference mitigation strategy for IEEE 802.15.4 system to maintain communications during times of interference by ensuring reliable multi-hop transmission. Experiment results prove that this strategy is effective for maintaining the transmission among sensor nodes in IEEE 802.15.4 network.
