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

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

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

Gothic: a group access control architecture for secure multicast and anycast
Proceedings - IEEE INFOCOM - Tập 3 - Trang 1547-1556 vol.3
P. Judge, M. Ammar
Multicast and anycast have received considerable attention due to their ability to support networked services. There are distinct and significant security vulnerabilities in both the multicast and anycast model including denial of service, theft or service, eavesdropping, and masquerading. The multicast problem requires a secure IGMP. The anycast problem requires secure anycast server advertisemen...... hiện toàn bộ

Extremal traffic and bounds for the mean delay of multiplexed regulated traffic streams
Proceedings - IEEE INFOCOM - Tập 2 - Trang 985-993 vol.2
F.M. Guillemin, N. Likhanov, R.R. Mazumdar, C. Rosenberg
In this paper, we present simple performance bounds for multiplexed regulated traffic streams, which are leaky-bucket regulated with peak, mean rate and burst size constraints. We consider independent, heterogeneous streams, which are multiplexed in a common buffer. We derive bounds on the mean delay in the deterministic context and we then obtain a simple stochastic bound, which is exact when the...... hiện toàn bộ

An efficient buffer management policy based on an integrated fuzzy-GA approach
Proceedings - IEEE INFOCOM - Tập 2 - Trang 1042-1048 vol.2
G. Ascia, V. Catania, D. Panno
This paper deals with a novel buffer management scheme based on evolutionary computing for shared-memory ATM switches. The philosophy behind it is adaptation of the threshold for each output logical queue to the real traffic conditions by means of a system of fuzzy inferences. The optimal fuzzy system is achieved using a systematic methodology based on genetic algorithms for membership-function se...... hiện toàn bộ

Joint scheduling and power control for wireless ad-hoc networks
Proceedings - IEEE INFOCOM - Tập 2 - Trang 976-984 vol.2
T. ElBatt, A. Ephremides
In this paper we introduce power control as a solution to the multiple access problem in contention-based wireless ad-hoc networks. The motivation for this study is two fold, limiting multi-user interference to increase single-hop throughput, and reducing power consumption to increase battery life. We focus on next neighbor transmissions where nodes are required to send information packets to thei...... hiện toàn bộ

Beyond routing: an algebraic approach to network coding
Proceedings - IEEE INFOCOM - Tập 1 - Trang 122-130 vol.1
R. Koetter, M. Medard
We consider the issue of network capacity. Recent work by Li and Yeung examined the network capacity of multicast networks and related capacity to cutsets. Capacity is achieved by coding over a network. We present a new framework for studying networks and their capacity. Our framework, based on algebraic methods, is surprisingly simple and effective. For networks which are restricted to using line...... hiện toàn bộ

Energy efficient communications in ad hoc networks using directional antennas
Proceedings - IEEE INFOCOM - Tập 1 - Trang 220-228 vol.1
A. Spyropoulos, C.S. Raghavendra
Directional antennas can be useful in significantly increasing node and network lifetime in wireless ad hoc networks. In order to utilize directional antennas, an algorithm is needed that will enable nodes to point their antennas to the right place at the right time. In this paper we present an energy-efficient routing and scheduling algorithm that coordinates transmissions in ad hoc networks wher...... hiện toàn bộ

Dynamics of TCP/RED and a scalable control
Proceedings - IEEE INFOCOM - Tập 1 - Trang 239-248 vol.1
S.H. Low, F. Paganini, Jiantao Wang, S. Adlakha, J.C. Doyle
We demonstrate that the dynamic behavior of queue and average window is determined predominantly by the stability of TCP/RED, not by AIMD probing nor noise traffic. We develop a general multi-link multi-source model for TCP/RED and derive a local stability condition in the case of a single link with heterogeneous sources. We validate our model with simulations and illustrate the stability region o...... hiện toàn bộ
