Push provides the automated and personalized web information delivery. Users can subscribe their interested channels from content providers. These channels will be delivered to users automatically in each update. Among all the components involved in a push system, transmitter manages the deployment and maintenance of information channels. In this paper, a content-based channel scheduling mechanism for transmitters is designed and evaluated. Instead of push information by arriving order, transmitter takes three more factors into account, i.e. the channel update period, the size of content, and the waiting time of content in queue. Transmitter delivers channels by their calculated priorities. Study the results from our XML-based simulation system, the new channel scheduling algorithm not only improve the average responding time, but also decrease the average loss rate.
