在本文中，我们提出了一种新的数据包传输机制称为多路径和多速度路由协议（MMBEPE）的概率QoS保证在无线传感器网络。QoS提供在两个质量域中执行，即，及时性和可靠性。通过保证多个分组递送速度选项，在时效性域中提供多个QoS级别。在可靠性域中，概率多路径转发支持各种可靠性要求。这些机制的QoS供应实现在本地化的方式没有全球网络信息，通过采用本地化的地理数据包转发与动态补偿，这补偿了本地决策的不准确性，作为一个包向其目的地。这样，MMSPEED可以以本地化的方式保证端到端的要求，这对于大规模动态传感器网络的可扩展性和适应性是期望的。仿真结果表明，MMSPEED提供QoS区分在可靠性和及时性域，因此，显着提高了传感器网络的有效容量方面的流量，同时满足可靠性和及时性的要求高达50%（12流与18流）。
In this paper, we present a novel packet delivery mechanism called Multi-Path and Multi-SPEED Routing Protocol (MMSPEED) for probabilistic QoS guarantee in wireless sensor networks. The QoS provisioning is performed in two quality domains, namely, timeliness and reliability. Multiple QoS levels are provided in the timeliness domain by guaranteeing multiple packet delivery speed options. In the reliability domain, various reliability requirements are supported by probabilistic multipath forwarding. These mechanisms for QoS provisioning are realized in a localized way without global network information by employing localized geographic packet forwarding augmented with dynamic compensation, which compensates for local decision inaccuracies as a packet travels towards its destination. This way, MMSPEED can guarantee end-to-end requirements in a localized way, which is desirable for scalability and adaptability to large scale dynamic sensor networks. Simulation results show that MMSPEED provides QoS differentiation in both reliability and timeliness domains and, as a result, significantly improves the effective capacity of a sensor network in terms of number of flows that meet both reliability and timeliness requirements up to 50 percent (12 flows versus 18 flows).
