A Multipath Routing Algorithm Based On Service-aware For Wireless Multimedia Sensor Networks

Traditional Wireless Sensor Network (WSN) is just used to transmit some simpledata, and Wireless Multimedia Sensor Networks (WMSNs) can transmit and processlarge amounts of large data while its sensor nodes can sense such as audio, video andso on.They are typically deployed in poor conditions or unattended scene.However, the characteristics of energy-limited、dynamic mobile and unstable inWMSNs make it difficult to transmit large multimedia data stream. It can’t meetneeds. Therefore, in the case of limited energy and bandwidth, to provide with betterservice has become an urgent problem.This paper studies the service guarantee as well as multipath transmission,proposes an efficiency of the service model. A multipath routing algorithm isproposed on this model. This paper proposes a Service-aware node-Disjoint MultipathAlgorithm (SDMA). To establish a multipath with source routing, we defineefficiency model, and then forward RREQs(Route REQuest Messages) consideringrouting ID and service efficiency, and reduce overhead to establish routes. Thealgorithm can provide service support for different types of data, and the simulationresults show its effectiveness.The innovation of this article is to take into account the diversity of the types ofservices, and propose the model of a service efficiency, then on the basis of thismodel establish a corresponding node disjoint multipath transmission path, as a resultmeet requirements of user data transmission and improve overall networkperformance.Inter-node link quality and the residual energy of node power are quite differentin WMSNs, the introduction of high-quality links and high-energy nodes in therouting can meet the needs of different types of services, improve data transmission reliability, save single node transmission energy consumption and balance the entirenetwork energy.
