Abstract
Aiming at three basic services
abnormal event alarm
information query and stream query service
the paper abstracts a QoS routing model for the multimedia sensor networks.Moreover
based on the traditional ant-based algorithm
we propose an ant-colony optimization based service aware routing (ASAR).The ASAR chooses the suitable paths to satisfy with the diverse QoS requirements from different kinds of service
thus maximizes network utilization and improves network performance.Finally
extensive simulation using NS2 is conducted to verify the effectiveness of our solution.Compared to the traditional ant-based algorithm
our ASAR algorithm has better convergence and significantly provides better QoS for multiple types of services in the multimedia sensor networks.
