<FONT face=Verdana>In RFID information service networks
an innovative routing algorithm supporting composite subscriptions and taking system reliability into consideration is designed.In subscription forwarding
we decompose each composite subscription and assign each of its composite elements to multiple RFID information services to maintain
while events are forwarded along the reverse path of the subscription factorizing direction based on the matching work.In order to keep the consistency of multiple copies of a composite subscription and to ensure the correctness of message forwarding
we import heartbeat messages.The simulation results show that the routing algorithm has strong fault-tolerance and its performance can satisfy the need of application.
