A new technique is proposed that enables TCP to early detect packet losses, which cannot be detected and retransmitted using the standard fast retransmit mechanism, and to quickly retransmit those packets without waiting for a timeout to occur, thereby improving TCP performance. Early Packet Loss Recovery (EPLR) is achieved by considering the expected number of acknowledgements and the number o...

Imagine a network technology that routinely loses information, experiences variable and unpredictable delay in data delivery, and makes no distinction between applications with different communication requirements. Next, imagine that the use of this technology is growing exponentially and that, even as networks become increasingly congested, its applications are being extended to global-scale v...

IEEE Standard 802.16 sets the stage for broadband wireless access system. This standard includes the medium access control layer (MAC) and physical layer with higher data rates and longer transmission range compared to those supported by the existing wireless technologies. It also provides QoS (Quality of Service) for the applications such as Voice over IP, video streaming and high bandwidth fi...

Mix networks are a popular mechanism for anonymous Internet communications. By routing IP traffic through an overlay chain of mixes, they aim to hide the relationship between its origin and destination. Using a realistic model of interactive Internet traffic, we study the problem of defending low-latency mix networks against attacks based on correlating inter-packet intervals on two or more lin...

[Abstract] In this paper, the transport efficiency of Multi Protocol Encapsulation (MPE), Unidirectional Lightweight Encapsulation (ULE) and Generic Stream Encapsulation (GSE) for typical IP packet sizes is compared. Moreover, the aggregated efficiency when applying packet-level forward error correction (PL-FEC) with MPE, ULE and GSE is also analyzed. MPE-FEC is the mechanism used by DVB-H wher...

This paper describes a forward link multi carrier packet scheduler method for a high-speed packet data communication system. A proportional fairness method has been proposed to realize high data throughput. This paper proposes a modification to the proportional fairness method to add multi carrier capability for the improvement of data throughput. In the proposal, an access terminal with capabi...

future design procedures for civil structures, especially those to be protected from extreme and blast relatedloads, will need to account for temporal evolution of their frequency content. there are, however, several instanceswhere acceleration time histories are required as seismic input. for example, to determine the ultimate resistance andto identify modes of structures’ failure, a nonlinear...

the increasing diversity in packet-processing applications together with the rapid increase in channel bandwidth has brought about greater complexity in communication protocols. also influenced by these factors is the computational load for packet-processing engines, demanding high performance microprocessor designs as an indispensable solution. this paper reports on extensive simulation experi...

While today's computer networks supports only best-effort service, future packet-switching integrated-services networks will have to support real-time communication services that allow clients to transport information with performance guarantees expressed in terms of delay, delay jitter throughput and loss rate. An important issue in providing guaranteed performance service is the choice of pac...

Mobile Ad Hoc Network (MANET) is a wireless telecommunications technology that consists of collection dynamic nodes. Due to these properties resulted in the mobility nodes MANET. So every relationship between will always change and cause process finding vulnerable route take long time. Each node also has role as host or router exchanging information. In MANET delivery assurance ability deal wit...
