    Satellite communication systems exhibit important and unique features that qualify them to be an integral part of a global ubiquitous information system. Given the universality of the Internet protocol (IP), traffic over satellite network is expected to be all IP. Success of these all-IP satellite systems depends on their abilities to guarantee QoS. QoS provisioning has been a hot topic in terrest... View full abstract»

    The paper analyzes the performance of the bandwidth allocation process over satellite communication systems in presence of specific quality of service (QoS) requirements. The reference allocation algorithms considered are based on multi-objective programming (MOP) and are called "Utopia minimum distance" (UMD), "constrained Utopia minimum distance" (CUMD) and "QoS point minimum distance" (QPMD).

    The datagram congestion control protocol (DCCP) is a new IETF-defined transport protocol for Internet multimedia. The DCCP congestion control identifier 4 (CCID4) was specifically designed to support the stream of small packets generated by applications such as voice over IP (VoIP). This uses equation based congestion control. The long round trip delay when the path includes a satellite link could... View full abstract»

    This paper introduces a buffer occupancy-based admission control mechanism aimed to counter link congestion while fairly sharing the bandwidth in converged IP and broadcasting networks. The proposed connection admission control (CAC) scheme favors fairness and downlink bandwidth sharing between different served satellite terminals (sub-networks) in presence of congestion events. Our CAC is intende... View full abstract»

    In this paper, a location-assisted on-demand routing (LAOR) protocol for low earth orbit (LEO) satellite systems is proposed and evaluated. This protocol can be viewed as a variant of the well-known ad-hoc on-demand distance vector (AODV) routing protocol, tailored to the requirements imposed by the characteristics of LEO satellite systems' topology. The LAOR protocol is assessed for different lin... View full abstract»

  • M-gated Scheduling in Wireless Networks: Performance and Cross-layer Design

    E-limited (or K-limited) scheduling is attractive because its performance is close to that of the exhaustive scheduling which is proven to be the optimal polling scheme for symmetric systems (same traffic offered to all queues) by some researches. If the parameter K is chosen properly, E- limited scheduling can avoid the unfairness, which is an inherent problem for the exhaustive service on a shor... View full abstract»

  • Performance Analysis of Adaptively-Routed Wormhole-Switched Networks with Finite Buffers

    The use of adaptively-routed wormhole switched k-ary n-cubes has been motivated by the high path diversity provided by the rich topology of this family of interconnection networks. Due to its insensitivity to message destination, adaptive wormhole switching has been an attractive design alternative not only in networks suggested for contemporary multicomputers but also in the new Network-on-Chip a...

    Transferring data reliably from Mars to Earth stations is becoming an appealing challenge in the design of interplanetary networks. In this view, the use of CCSDS-based protocols along with erasure codes is a promising candidate for mitigating the performance degradation due to large propagation delays and high packet loss rates. Besides, the constraints imposed on the transmission power and on th... View full abstract»

    Peer-to-peer (P2P) networks are emerging as an interesting alternative to media streaming delivery with respect to content delivery networks (CDN). Although several P2P protocols have been proposed to support video streaming with an adequate degree of quality of service (QoS), a critical point today is how to evaluate them and optimize their parameters. The difficulty lies in the fact that the beh... View full abstract»

    Considering user behaviors in the performance evaluation of mobile networks is crucial as traffic generation in such networks is highly dependent on mobility and communication activities of mobile users. This paper presents a simulator that can faithfully simulate user behaviors together with the target network system. The following three components have been implemented in a network simulator in ...

    Media stream quality is highly dependent on underlying network conditions, but identifying scalable, unambiguous metrics to discern the user-perceived quality of a media stream in the face of network congestion is a challenging problem. User-perceived quality can be approximated through the use of carefully chosen application layer metrics, precluding the need to poll users directly. We discuss th... View full abstract»

    When constructing an unstructured P2P topology, one should consider the application running on top of it in order to achieve a good performance for the whole P2P system. It is not enough only to consider the "topology" objective when forming an overlay such as minimizing a P2P network diameter because it does not achieve a good performance for the whole P2P system. For example, minimizing a P2P ne... View full abstract»

    In this paper, the IEEE 802.16 protocol is investigated with respect to the bandwidth provision problem arising at the medium access control (MAC) layer. The aim is to optimally tune the resource allocation to match QoS requirements. Traffic flows are originated at network layers overlying the 802.16 protocol stack. This leads to the investigation of a novel control algorithm, suited to optimal ba... View full abstract»

    A QoS constrained scheduling framework is presented and evaluated for VoIP traffic. QoS factors such as frame error rate, delay, codec related quality factors are added to the proportional fair scheduler in different manners to enhance the scheduler support for real-time traffic, like VoIP. Simulations show that the new scheduler improves the link level quality/fairness and the system capacity. View full abstract»

    Wireless Mesh Networks represent an interesting technology due to their reliability, broad coverage and relatively easy and inexpensive scalability. The architecture is mainly a hybrid solution between ad-hoc and infrastructure networking, where each node potentially acts as a relay, forwarding traffic generated by other nodes. Even if solutions are already available, many research topics have yet... View full abstract»

    In this paper, we propose a distributed power control algorithm for multihop ad hoc CDMA networks. The algorithm attempts to maximize the QoS of each user as well as a global network utility, given a set of routes and link schedules. By defining the local objective of each node as a summation of its own utility and that of the "bottleneck" nodes in its vicinity, users are considered partially coop... View full abstract»
