In this paper, the Adaptive Overlay Multicast (AOM) protocol is presented, which is specially beneficial to long-lasting, large data distribution applications with large receiver sets. AOM distinguishes itself from previous research with the following characteristics: (1) Scalable overlay multicast tree construction method and a scoping technique to(More)
Overlay multicast protocols should adapt to the dynamic network environment to maintain application performance. We show how end-to-end network metrics can be used in the dynamic adaptation and thus improve the performance of the direct-tree overlay multicast protocols while providing good tree quality. We propose the adaptive overlay multicast (AOM)(More)
In this paper, we present an energy conservation scheme for wireless ad hoc and sensor networks using gossiping to place nodes in an energy saving sleep state. The technique is termed the Gossip-based Sleep Protocol (GSP). With GSP, each node randomly goes to sleep for some time with gossip sleep probability p. GSP is based on the observation that in a well(More)
Recently, we have proposed an energy saving Gossip-based Sleep Protocol (GSP) [1] for energy conservation in mobile ad hoc networks. A gossiping node employs a random variable (p) to decide whether or not to enter a sleep mode. Our observation is that in a well connected ad hoc network there are usually many paths existing between a source and a(More)
In reliable multicast applications, packet loss needs to be reported by having group members send feedback messages. This results in the well-known feedback implosion problem. The available feedback control mechanisms can be classified as timer-based, hierarchy-based and router-assisted, among which the timer-based approach is more preferable due to its(More)
Reliable multicast applications use feedback messages to report receiving status of receivers. This results in the well-known feedback implosion and scalability problems. Also, quick loss response from receivers and low multicast overhead, e.g. control messages and session messages, are desired. We present a feedback implosion control mechanism that groups(More)

New therapeutic intervention strategies for the treatment of human malignancies are always desired. Approval of bortezomib as a front-line treatment for multiple myeloma highlighted the significance of ubiquitin-proteasome system (UPS) as a promising therapeutic target. However, due to the broad impact of proteasome inhibition, deleterious side effects have(More)
This paper presents the transient performancestudy on the adaptability of an application layer multicastprotocol, namely Adaptive Overlay Multicast (AOM). The studyfocuses on how the application layer multicast tree structure adapts to network dynamics and faults by using efficient tree management and adaptation algorithms, thus reducing the adverse effects(More)
