Service-driven routing algorithm over multimedia sensor networks
Xuewu Zhang · Computer Engineering and Applications Journal · 2011
Aiming at the diversity of bearer service for multimedia sensor networks and QoS requirements for different services(e.g.video/image services,audio services and data services),a business-driven QoS routing model is abstracted for multimedia sensor networks and a Service-Driver Routing algorithm(SDR) is proposed based on ant colony algorithm and chaos theory.The SDR algorithm selects corresponding routing strategy according to different QoS requirements for different services,to reach the targets of using the network resources fully and enhancing the network load business performance.Finally, the routing algorithm is simulated using NS2.Compared with other methods,the simulation results show that the proposed algorithm can better satisfy the QoS requirements for differentiated services.
