Reliable multicast in wireless Ad hoc networks was studied based on network coding,with the goal of minimizing the total number of retransmissions.
为了最小化发送节点重传的总次数,对无线Ad hoc网络中基于网络编码的可靠组播技术进行了研究。
In this paper, we mainly introduce the issue of how to resolve the loss of bursts due to contending for link resource among data bursts in OBS networks, and discuss some loss recovery strategies in OBS such as burst cloning, forward redundancy and retransmission.
着重探讨了解决光突发交换网中突发数据包之间争夺链路资源引起数据丢失的丢失恢复机制,主要包括突发克隆、前向冗余、重传等机制,对这些技术的优缺点进行了比较分析,并提出了一种改进方案。
Firstly authors deduce the expressions of the expected value of link utilization under static unicast and multicast retransmission mode (E and E), and find E is always smaller than E, which means unicast retransmission mode is in favor of avoiding congestion in the wireless interfaces.
在移动环境下 ,组播的重传方式是影响系统性能的重要问题 ,如采用静态多播重传方式 ,将使许多终端收到重复数据包 ,由于移动终端带宽、电力资源紧缺 ,重复传输将可能造成终端链路利用率过高 ,严重浪费终端资源 ;如采用静态单播重传方式 ,在丢包接受者数量很多时 ,又将导致较大网络负荷 。
In addition, a "Store-Resend" technique is proposed to solve the packet lost problem.

Pulsing denial-of-service(PDoS)attack is a new class of DoS attack,which exploits the deficiencies of the minimum retransmission time out(RTO) of TCP to send out short bursts of attack packets to a victim.
Pulsing denial-of-service(PDoS)攻击是一种新型的DoS攻击,它主要利用TCP超时重传机制的弱点,使用周期性的短脉冲向受害者发起攻击,由于平均攻击速率较低,传统的检测机制对其无法检测。
