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.

NetTS- NR：移动的Ad Hoc网络的adhoc拥塞控制Saad Biaz，奥本UniversityAward 0435320摘要本项目正在开发特别适用于移动的ad hoc网络（MANDON）的ad hoc端到端拥塞控制技术。 在移动的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分组丢失不符合作为可靠拥塞指示器的资格，并且要求ad hoc拥塞控制算法必须（1）准确地诊断丢失的真实的原因以及（2）适当地对每种类型的丢失做出反应。 该研究小组正在研究一个创新的方向，以开发一个准确的丢失率和一个隐式的连续拥塞度量，该度量基于数据包丢失并产生更好的性能。 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分组并在所有中间节点处启用有偏队列管理来实现的，使得它们可以在拥塞发生时瞄准并丢弃具有最高丢弃优先级的分组。 一个明智的标记允许TCP隐式地估计拥塞。 该项目的攻击理论和系统的挑战，并将使移动自组网的实际部署。 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。
