    Although the original intent of the peer-to-peer (P2P) concept is to treat each participant equally, heterogeneity widely exists in deployed P2P networks. Peers are different from each other in many aspects, such as bandwidth, CPU power, and storage capacity. Some approaches have been proposed to take advantage of the query forwarding heterogeneity such that the high bandwidth of powerful nodes ca... View full abstract»

    In the future, we are likely to see a tremendous need for context-aware applications which adapt to available context information such as physical surroundings, network, or system conditions. We aim to provide a fundamental support for these applications - a real-time context information collection service. This service delivers the right context information to the right user at the right time. Th... View full abstract»

  • Handling Topology Changes in InfiniBand

    InfiniBand is a high-performance switched network. Its topology may change due to devices being turned on/off, hot expansion, link remapping, and component failures. The InfiniBand specification defines a management infrastructure which is responsible for detecting and assimilating any change in the network. When a change occurs, management entities must update switch forwarding tables, in order t... View full abstract»

    To explore the advantages of power saving offered by the wireless multicast advantage property, we consider the case of source-initiated multicast traffic. Current research activity for the minimum energy multicast (MEM) problem has been focused on devising efficient centralized greedy algorithms for static ad hoc networks. In this paper, we consider mobile ad hoc networks (MANETs) that use omnidi... View full abstract»

    An important phase of sensor networks operation is deployment of sensors in the field of interest. Critical goals during sensor networks deployment include coverage, connectivity, load balancing, etc. A class of work has recently appeared, where mobility in sensors is leveraged to meet deployment objectives. In this paper, we study deployment of sensor networks using mobile sensors. The distinguis... View full abstract»

  • Multimedia Object Placement for Transparent Data Replication

    Transparent data replication is a promising technique for improving the system performance of a large distributed network. Transcoding is an important technology which adapts the same multimedia object to diverse mobile appliances; thus, users' requests for a specified version of a multimedia object could be served by a more detailed version cached according to transcoding. Therefore, it is partic... View full abstract»

    Differentiated service (DiffServ) networks have been proposed to assure the achievable minimum bandwidth to aggregate flows. However, analyses in the literature show that the current DiffServ networks are biased in favor of ah aggregate flow that has a smaller committed information rate (CIR) when aggregate flows with different CIRs share a bottleneck link. In order to mitigate this unfairness pro... View full abstract»

  • uCast: Unified Connectionless Multicast for Energy Efficient Content Distribution in Sensor Networks

    In this paper, we present uCast, a novel multicast protocol for energy efficient content distribution in sensor networks. We design uCast to support a large number of multicast sessions, especially when the number of destinations in a session is small. In uCast, we do not keep any state information relevant to ongoing multicast deliveries at intermediate nodes. Rather, we directly encode the multi... View full abstract»

    Most of the current communication networks, including the Internet, are packet switched networks. One of the main reasons behind the success of packet switched networks is the possibility of performance gain due to multiplexing of network bandwidth. The multiplexing gain crucially depends on the size of the buffers available at the nodes of the network to store packets at the congested links. Howe... View full abstract»

  • A Message Scheduling Scheme for All-to-All Personalized Communication on Ethernet Switched Clusters

    We develop a message scheduling scheme for efficiently realizing all-to-all personalized communication (AAPC) on Ethernet switched clusters with one or more switches. To avoid network contention and achieve high performance, the message scheduling scheme partitions AAPC into phases such that 1) there is no network contention within each phase and 2) the number of phases is minimum. Thus, realizing... View full abstract»

    Many research activities on wireless sensor networks (WSNs) need detailed performance statistics about protocols, systems, and applications; however, current simulation tools and testbeds lack mechanisms to report these statistics realistically and conveniently. To address this need, we have developed a WSN emulator, VMNet. VMNet emulates networked sensor nodes at the level of CPU clock cycles and... View full abstract»
