面向服务的无线传感器网络体系结构为新的应用提供了一个集成的平台，可以通过灵活的服务组合快速开发新的应用。在无线传感器网络中，现有的多路径路由方案已经证明了在多路径上分配流量以满足应用的服务质量要求的有效性。然而，链路故障可能会显着影响无线传感器网络的传输性能，可扩展性，可靠性和安全性。因此，通过考虑多路径的可靠性、拥塞控制和安全性，期望设计可靠的和服务驱动的路由方案以提供高效的和容错的路由方案。本文提出了一个评价指标，路径空闲率，评估，然后找到一组链路不相交的路径从所有可用的路径。提出了一种自适应调整多径网络负载的拥塞控制和负载均衡算法。一个阈值共享算法被应用到分裂成多个段，将通过多路径传递到目的地取决于路径空置率的数据包。仿真结果表明，自适应和安全的负载平衡路由方案的性能。
Service-oriented architectures for wireless sensor networks (WSNs) have been proposed to provide an integrated platform, where new applications can be rapidly developed through flexible service composition. In WSNs, the existing multipath routing schemes have demonstrated the effectiveness of traffic distribution over multipaths to fulfill the quality of service requirements of applications. However, the failure of links might significantly affect the transmission performance, scalability, reliability, and security of WSNs. Thus, by considering the reliability, congestion control, and security for multipath, it is desirable to design a reliable and service-driven routing scheme to provide efficient and failure-tolerant routing scheme. In this paper, an evaluation metric, path vacant ratio, is proposed to evaluate and then find a set of link-disjoint paths from all available paths. A congestion control and load-balancing algorithm that can adaptively adjust the load over multipaths is proposed. A threshold sharing algorithm is applied to split the packets into multiple segments that will be delivered via multipaths to the destination depending on the path vacant ratio. Simulations demonstrate the performance of the adaptive and secure load-balance routing scheme.
