An investigation is made of an optimal task-assignment policy for a random-graph model of a distributed program. The model of the distributed computer system assumes that communications overhead adds to total run time and that total run time decreases as the number of processors running the program is increased. When the processors are homogeneous, the(More)
The inter-domain routing system is a complex macrosystem just like the Internet, and the self-organization theory is the efficient utility for studying complex system. This paper analyzes the intrinsic rules and behavioral exhibitions of inter-domain routing system from the view of self-organization, and evaluates the mending methods to BGP protocol for(More)
Based on the characteristics of evolution, autonomy and diversity of Internet resources, researchers recently proposed to realize the publication and query of Internet resource information through common DHT (distributed Hash table) information services. However, current research on resource information services is insufficient in generality, usability and(More)
Many emerging mobile wireless applications depend upon secure group communication, in which a secure and efficient group rekeying algorithm is very important. In this paper, a rekeying algorithm named DGR (distributed group rekeying algorithm) is proposed, which is based on DGKMF (distributed group key management framework). DGR algorithm generates a group(More)
A cluster-based multipath routing algorithm in mobile ad hoc networks. Abstract: This paper proposes a cluster-based multi-path routing in MANET (CBMRP). It distributes traffic among diverse multiple paths to avoid congestion, optimize bandwidth used and improve the sharing rate of channel. It uses clustering's hierarchical structure diverse to decrease(More)
As an instance of Internet resource sharing based virtual computing environment, iVCE (Internet based virtual computing environment) for Memory try to solve the problem of memory resource sharing and utilization. Due to the special properties of memory resource, traditional resource management approaches can not be adapted easily. A clustering based(More)
RAM (random access memory) Grid is a new grid system aiming at memory resources sharing in wide-area network; it can improve the performance of memory intensive or IO intensive applications when lack of physical memory. Reducing or hiding the network overhead can improve the performance of RAM Grid, which lies on the overhead of network communication. In(More)
Based probabilistic reliable dissemination for mobile ad hoc networks. Abstract: This paper proposes PLPD, a novel percolation-based probabilistic reliable dissemination protocol for information dissemination among a group of nodes in a MANET. Being different from other probabilistic reliable dissemination protocols, PLPD is aware of the network topology(More)
Differentiated services (DiffServ) is a scalable architecture for supporting quality of services (QoS), and video multicast is the application which needs network to support QoS guarantee. To accommodate to heterogeneous network and host, it is a good idea to transmit video in a few layers. The paper proposes LVMM (layered video multicast meter) and LVMF(More)
