Adaptive bandwidth reservation and admission control in QoS-sensitive cellular networks
IEEE Transactions on Parallel and Distributed Systems - Tập 13 Số 9 - Trang 882-897 - 2002
How to keep the probability of hand-off drops within a prespecified limit is a very important quality-of-service (QoS) issue in cellular networks because mobile users should be able to maintain ongoing sessions even during their hand-off from one cell to another. We design and evaluate predictive and adaptive schemes for bandwidth reservation for the hand-offs of ongoing sessions and the admission...... hiện toàn bộ

On the asymptotical optimality of multilayered decentralized consensus protocol
IEEE Transactions on Parallel and Distributed Systems - Tập 13 Số 8 - Trang 769-786 - 2002
A decentralized consensus protocol refers to a process for all nodes in a distributed system to collect the information/status from every other node and reach a consensus among them. Two classes of decentralized consensus protocols have been studied before: the one without an initiator and the one with an initiator. While the one without an initiator has been well studied in the literature, it is ...... hiện toàn bộ

Optional and responsive fine-grain locking in Internet-based collaborative systems
IEEE Transactions on Parallel and Distributed Systems - Tập 13 Số 9 - Trang 994-1008 - 2002
Locking is a standard technique used in distributed computing and database systems to ensure data integrity by prohibiting concurrent conflicting updates on shared data objects. Internet-based collaborative systems are a special class of distributed applications which support human-to-human interaction and collaboration over the Internet. In this paper, a novel optional and responsive fine-grain l...... hiện toàn bộ

On load balancing for distributed multiagent computing
IEEE Transactions on Parallel and Distributed Systems - Tập 13 Số 8 - Trang 787-801 - 2002
Multiagent computing on a cluster of workstations is widely envisioned to be a powerful paradigm for building useful distributed applications. The agents of the system span across all the machines of a cluster. Just like the case of traditional distributed systems, load balancing becomes an area of concern. With different characteristics between ordinary processes and agents, it is both interestin...... hiện toàn bộ

Addressing and routing in hexagonal networks with applications for tracking mobile users and connection rerouting in cellular networks
IEEE Transactions on Parallel and Distributed Systems - Tập 13 Số 9 - Trang 963-971 - 2002
Nodes in a hexagonal network are placed at the vertices of a regular triangular tessellation, so that each node has up to six neighbors. The network is proposed as an alternative interconnection network to a mesh connected computer (with nodes serving as processors) and is used also to model cellular networks where nodes are the base stations. In this paper, we propose a suitable addressing scheme...... hiện toàn bộ

Extended dominating-set-based routing in ad hoc wireless networks with unidirectional links
IEEE Transactions on Parallel and Distributed Systems - Tập 13 Số 9 - Trang 866-881 - 2002
We extend dominating-set-based routing to networks with unidirectional links. Specifically, an efficient localized algorithm for determining a dominating and absorbant set of vertices (mobile hosts) is given and this set can be easily updated when the network topology changes dynamically. A host /spl nu/ is called a dominating neighbor (absorbant neighbor) of another host u if there is a directed ...... hiện toàn bộ

An efficient parallel algorithm for the efficient domination problem on distance-hereditary graphs
IEEE Transactions on Parallel and Distributed Systems - Tập 13 Số 9 - Trang 985-993 - 2002
In the literature, there are quite a few sequential and parallel algorithms for solving problems on distance-hereditary graphs. With an n-vertex and m-edge distance-hereditary graph G, we show that the efficient domination problem on G can be solved in O(log/sup 2/ n) time using O(n + m) processors on a CREW PRAM. Moreover, if a binary tree representation of G is given, the problem can be optimall...... hiện toàn bộ

Scalable stability detection using logical hypercube
IEEE Transactions on Parallel and Distributed Systems - Tập 13 Số 9 - Trang 972-984 - 2002
This paper proposes to use a logical hypercube structure for detecting message stability in distributed systems. In particular, a stability detection protocol that uses such a superimposed logical structure is presented, and its scalability is compared with other known stability detection protocols. The main benefits of the logical hypercube approach are scalability, fault-tolerance, and refrainin...... hiện toàn bộ

Locating mobile agents in a wide distributed environment
IEEE Transactions on Parallel and Distributed Systems - Tập 13 Số 8 - Trang 844-864 - 2002
Finding the position of a mobile agent in a wide distributed system still represents an open research issue. The paper proposes a naming scheme and a location protocol of general validity for mobile agents able to effectively meet all the typical requirements of mobile agent environments and, thus, easy to integrate into different platforms. The paper identifies the main characteristics which an a...... hiện toàn bộ

An efficient synchronization scheme of multimedia streams in wireless and mobile systems
IEEE Transactions on Parallel and Distributed Systems - Tập 13 Số 9 - Trang 911-923 - 2002
Recent advances in mobile computing and distributed multimedia systems allow mobile hosts (clients) to access wireless multimedia systems anywhere and at anytime, but not without creating a new set of issues and trade-offs. To the best of our knowledge, there has been very little research in dealing with the synchronization problem in wireless and mobile multimedia systems. In this paper, we propo...... hiện toàn bộ
