As wireless connectivity is integrated into many handheld devices, streaming multimedia content among mobile ad-hoc peers is becoming a popular application. In this paper, we introduce a new QoS criterion called path-availability-based service coverage to mobile streaming applications. Based on this QoS criterion, we propose a dynamic service replication strategy for providing guaranteed continuous streaming service to all nodes in mobile ad-hoc networks (MANETs). Unlike previous approaches that rely on remaining link duration to determine when service replication should be invoked, in our strategy, a client requests service replication when the path availability between the client and a server instance drops below a certain threshold. This strategy is based on our previous work on continuous link availability, which proves to be helpful in achieving smooth streaming performance in MANETs. Simulation results show that our service replication algorithm can quickly increase the service coverage to 100% while reducing the chance of link breakdowns during service replication.
