对等网络和移动网络引起了研究界和产业界的极大关注。在移动网络中应用对等范例会导致有关对等网络的带宽需求的几个问题。时间关键型消息的延迟和传递速度慢得令人无法接受。除此之外，稀缺的带宽被浪费在优先级较低的消息上。因此，本文的重点是覆盖层的带宽管理问题以及如何解决这些问题。提出了一种基于优先级的调度和主动队列管理系统HIPNOS.KOM。它保证对等系统的上层网络层中优先级较高的消息具有更好的服务质量。使用点对点模拟器PeerfactSim进行评估。KOM显示，与FIFO和Drop-Tail相比，HiPNOS.KOM在Kademlia中带来了显著的改进，这两种策略目前在每个对等点上都使用。使用HipNOS.KOM时，用户发起的查找在Kademlia中的操作持续时间缩短了24%。
Peer-to-peer and mobile networks gained significant attention of both research community and industry. Applying the peer-to-peer paradigm in mobile networks lead to several problems regarding the bandwidth demand of peer-to-peer networks. Time-critical messages are delayed and delivered unacceptably slow. In addition to this, scarce bandwidth is wasted on messages of less priority. Therefore, the focus of this paper is on bandwidth management issues at the overlay layer and how they can be solved. We present HiPNOS.KOM, a priority based scheduling and active queue management system. It guarantees better QoS for higher prioritized messages in upper network layers of peer-to-peer systems. Evaluation using the peer-to-peer simulator PeerfactSim. KOM shows that HiPNOS.KOM brings significant improvement in Kademlia in comparison to FIFO and drop-tail, strategies that are used nowadays on each peer. User initiated lookups have in Kademlia 24% smaller operation duration when using HiPNOS.KOM.
