Impact of network density on data aggregation in wireless sensor networks
- Trang 457-458
In-network data aggregation is essential for wireless sensor networks where energy resources are limited. In a previously proposed data dissemination scheme (directed diffusion with opportunistic aggregation), data is opportunistically aggregated at intermediate nodes on a low-latency tree. In this paper, we explore and evaluate greedy aggregation, a novel approach that adjusts aggregation points ......

Improving the scalability of fault-tolerant database clusters
- Trang 477-484
Replication has become a central element in modem information systems playing a dual role: increase availability and enhance scalability. Unfortunately, most existing protocols increase availability at the cost of scalability; This paper presents architecture, implementation and performance of a middleware based replication tool that provides both availability and better scalability than existing ......

Distributing MPEG movies over the Internet using programmable networks
- Trang 161-170
Distributing video over the Internet is an increasingly important application. Nevertheless, the real-time and high bandwidth requirements of video make video distribution over today's Internet a challenge. Adaptive approaches can be used to respond to changes in bandwidth availability while limiting the effect of such changes on perceptual quality and resource consumption. Nevertheless, most exis......

ControlWare: a middleware architecture for feedback control of software performance
- Trang 301-310
Attainment of software performance assurances in open, largely unpredictable environments has recently become an important focus for real-time research. Unlike closed embedded systems, many contemporary distributed real-time applications operate in environments where offered load and available resources suffer considerable random fluctuations, thereby complicating the performance assurance problem......

On peer-to-peer media streaming
- Trang 363-371
In this paper, we study a peer-to-peer media streaming system with the following characteristics: (1) its streaming capacity grows dynamically; (2) peers do not exhibit server-like behavior; (3) peers are heterogeneous in their bandwidth contribution; and (4) each streaming session may involve multiple supplying peers. Based on these characteristics, we investigate two problems: (1) how to assign ......

Process migration: a generalized approach using a virtualizing operating system
- Trang 385-392
Process migration has been used to perform specialized tasks, such as load sharing and checkpoint/restarting long running applications. Implementation typically consists of modifications to existing applications and the creation of specialized support systems, which limit the applicability of the methodology. Off the shelf applications have not benefited from process migration technologies, mainly......

Extending RMI to support dynamic reconfiguration of distributed systems
- Trang 401-408
By using dynamic reconfiguration, the flexibility, adaptability, and extensibility of distributed systems are enhanced. Treating interactions among components during dynamic reconfiguration is still one of the most crucial problems in this research area. This challenge should be met by middleware design and development. However, current standard middleware offers little support for dynamic reconfi......

Dynamic behaviour of the distributed tree quorum algorithm
- Trang 517-524
Mechanisms that ensure mutual access, replication and resilience to failures in large distributed systems can be based on quorum consensus. Effectiveness and scalability of the method selected are crucial. The aim of this paper is to present a message/time cost analysis of a distributed algorithm based on the tree quorum, which needs no global information, and has message complexity independent of......

From total order to database replication
- Trang 494-503
This paper presents in detail an efficient and provably correct algorithm for database replication over partitionable networks. Our algorithm avoids the need for end-to-end acknowledgments for each action while supporting network partitions and merges and allowing dynamic instantiation of new replicas. One round of end-to-end acknowledgments is required only upon a membership change event such as ......

Scheduling real-time data items in multiple channels and multiple receivers environments
- Trang 455-456
The problem of transmitting data items with timing constraint in the multiple broadcast channels where clients equipped with multiple receivers is studied. In our approach, the data items are divided into two sets, the broadcast data set and the on-demand data set. The data items in the broadcast data set is periodically broadcast on the broadcast channels while the data items in the on-demand dat......
