LI Yue, SHANG Zhi-jun, XU Chi, et al. A multi-channel MAC protocol in WSNs for electricity information acquisition system[J]. 2014, 33(10): 144-147. DOI: 10.13873/J.1000-9787(2014)10-0144-04.
As single-channel MAC protocol in wireless sensor networks(WSNs) cannot meet characteristic of the large amount of data and strong concurrency in electricity information acquisition system
a multi-channel MAC protocol for cluster networks is proposed.Parallel transmissions mode is used in intra-cluster communication;adaptive channel switching mechanism based on real-time link quality estimation is used in inter-cluster communication.Simulation results based on OMNeT + + show that compared with single-channel MAC protocol
this MAC protocol can effectively improve networks throughput and anti-interference reliability.
