| Abstract: | The LonWorks network introduces the predictive p-persistent CSMA algorithm to implement the media access control,which greatly reduces the collision rate of the network under heavy.loads and increase the channel efficiency.Meanwhile its character of real distribution has made the intelligent nodes especially the host-based nodes widely used in practice.By researching in this kind of intelligent module,the slave B mode of internal parallel was chosen to implement the internal data exchanging between Neuron chip and the master processor,and the response time between the nodes of the LonWorks network can be improved quite a lot. |
