A Quantitative Assured Forwarding service
Proceedings - IEEE INFOCOM - Tập 2 - Trang 864-873 vol.2
N. Christin, J. Liebeherr, T.F. Abdelzaher
The Assured Forwarding (AF) service of the IETF DiffServ architecture provides a qualitative service differentiation between classes of traffic, in the sense that a low-priority class experiences higher loss rates and higher delays than a high-priority class. However, the AF service does not quantify the difference in the service given to classes. In an effort to strengthen the service guarantees ...... hiện toàn bộ

Fast PDA synchronization using characteristic polynomial interpolation
Proceedings - IEEE INFOCOM - Tập 3 - Trang 1510-1519 vol.3
A. Trachtenberg, D. Starobinski, S. Agarwal
Modern personal digital assistant (PDA) architectures often utilize a wholesale data transfer protocol known as "slow sync" for synchronizing PDAs with personal computers (PCs). This approach is markedly inefficient with respect to bandwidth usage and latency, since the PDA and PC typically share many common records. We propose, analyze, and implement a novel PDA synchronization scheme (CPIsync - ...... hiện toàn bộ

Adaptive resource allocation in SDMA-based wireless broadband networks with OFDM signaling
Proceedings - IEEE INFOCOM - Tập 3 - Trang 1376-1385 vol.3
I. Koutsopoulos, L. Tassiulas
The increasing popularity of wireless broadband access in local and wide area networks is the main expression of the need for flexible and ubiquitous wireless connectivity. In order to satisfy user resource requirements in the presence of volatility of the wireless medium, sophisticated multiple access and adaptation techniques are required, which alleviate channel impairments and increase system ...... hiện toàn bộ

How good are deterministic fluid models of Internet congestion control?
Proceedings - IEEE INFOCOM - Tập 2 - Trang 497-505 vol.2
S. Shakkottai, R. Srikant
Congestion control algorithms used in the Internet are difficult to analyze or simulate on a large scale, i.e., when there are large numbers of nodes, links and sources in a network. The reasons for this include the complexity of the actual implementation of the algorithm and the randomness introduced in the packet arrival and service processes due to many factors such as arrivals and departures o...... hiện toàn bộ

Optimal MAC state switching for cdma2000 networks
Proceedings - IEEE INFOCOM - Tập 1 - Trang 400-406 vol.1
M. Chatterjee, S.K. Das
This paper deals with the performance modeling of the various MAC states as defined by the cdma2000 protocol. Our method uses a composite performance metric which has the capability of proportionally combining three basic parameters: channel utilization, waiting time and the saving in the signalling overhead. The scheduler at the base station is not only responsible for admitting new services into...... hiện toàn bộ

QoS routing for mobile ad hoc networks
Proceedings - IEEE INFOCOM - Tập 2 - Trang 958-967 vol.2
Chenxi Zhu, M.S. Corson
A quality-of-service (QoS) routing protocol is developed for mobile ad hoc networks. It can establish QoS routes with reserved bandwidth on a per flow basis in a network employing TDMA. An efficient algorithm for calculating the end-to-end bandwidth on a path is developed and used together with the route discovery mechanism of AODV to setup QoS routes. In our simulations the QoS routing protocol p...... hiện toàn bộ

On the throughput achievable by isolated and interconnected input-queueing switches under multiclass traffic
Proceedings - IEEE INFOCOM - Tập 3 - Trang 1605-1614 vol.3
E. Leonardi, M. Mellia, M.A. Marsan, F. Neri
Many studies provide an extended investigation of the maximum throughput achievable in input-queueing (IQ) or combined-input-and-output-queueing (CIOQ) packet switches. Some scheduling policies, among which are maximum weight matching algorithms, were identified as optimal, in the sense that they were proved to achieve 100% throughput under any admissible single-class traffic pattern. Most of the ...... hiện toàn bộ

MANETconf: configuration of hosts in a mobile ad hoc network
Proceedings - IEEE INFOCOM - Tập 2 - Trang 1059-1068 vol.2
S. Nesargi, R. Prakash
A mobile ad hoc network (MANET) is a multi-hop wireless network capable of autonomous operation. The mobility of MANET nodes can lead to frequent and unpredictable topology changes. Most MANET literature assumes that network related information of a node (such as its IP address, netmask, etc.) is configured statically, prior to the node joining the MANET. However, not all nodes have IP addresses p...... hiện toàn bộ

Energy-efficient scheduling of packet transmissions over wireless networks
Proceedings - IEEE INFOCOM - Tập 3 - Trang 1773-1782 vol.3
A. El Gamal, C. Nair, B. Prabhakar, E. Uysal-Biyikoglu, S. Zahedi
The paper develops algorithms for minimizing the energy required to transmit packets in a wireless environment. It is motivated by the following observation: In many channel coding schemes it is possible to significantly lower the transmission energy by transmitting packets over a long period of time. Based on this observation, we show that for a variety of scenarios the offline energy-efficient t...... hiện toàn bộ

FPAC: fast, fixed-cost authentication for access to reserved resources
Proceedings - IEEE INFOCOM - Tập 2 - Trang 1049-1058 vol.2
K.L. Calvert, S. Venkatraman, J.N. Griffioen
Enhanced network services often involve allocating resources (bandwidth/buffer space) preferentially to packets belonging to certain flows or traffic classes. Such services are vulnerable to denial-of-service attacks if packet classification is based on information that can be forged, such as source and destination addresses and port numbers. Traditional message authentication codes (MACs), often ...... hiện toàn bộ
