NeTS - NR: Ad hoc Congestion Control for Mobile Ad Hoc NetworksSaad Biaz, Auburn UniversityAward 0435320AbstractThis project is developing ad hoc end-to-end congestion control techniques particularly adapted to mobile ad hoc networks (MANETs). In mobile ad hoc networks, frequent link failures and other random losses unrelated to congestion disqualify packet loss as a reliable congestion indicator and require ad hoc congestion control algorithms that must (1) accurately diagnose the real cause of a loss and (2) appropriately react to each type of loss. The research team is investigating an innovative direction to develop an accurate loss discriminator and an implicit continuous congestion measure that is based on packet loss and yields better performance. The key to solving these problems is to "de-randomize" congestion losses. This is achieved by marking packets with different discard priorities and enabling biased queue management at all intermediate nodes so that they may target and drop packets with the highest discard priority when congestion occurs. A judicious marking allows senders to implicitly estimate congestion. This project attacks theoretical and systems challenges and will enable the practical deployment of MANETs. In addition, such challenges will help attract and educate talented graduate students and retain the brightest undergraduate students.

net - NR：移动自组织网络的自组织拥塞控制saad Biaz， Auburn大学奖0435320abstract该项目正在开发特别适用于移动自组织网络（manet）的自组织端到端拥塞控制技术。在移动ad hoc网络中，频繁的链路故障和其他与拥塞无关的随机丢失使丢包不能作为可靠的拥塞指标，并要求ad hoc拥塞控制算法必须(1)准确诊断出丢失的真正原因，(2)对每种类型的丢失做出适当的反应。研究小组正在研究一个创新的方向，开发一个准确的损失鉴别器和隐式连续拥塞测量，基于丢包和产生更好的性能。解决这些问题的关键是“去随机化”拥塞损失。这是通过标记具有不同丢弃优先级的数据包并在所有中间节点上启用有偏差队列管理来实现的，这样当拥塞发生时，它们可以瞄准并丢弃具有最高丢弃优先级的数据包。一个明智的标记允许发送方隐式地估计拥塞。该项目解决了理论和系统挑战，并将实现manet的实际部署。此外，这些挑战将有助于吸引和教育有才华的研究生，并留住最聪明的本科生。
