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......

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 ......

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......

Integration of pricing with call admission control to meet QoS requirements in cellular networks
IEEE Transactions on Parallel and Distributed Systems - Tập 13 Số 9 - Trang 898-910 - 2002
Call admission control (CAC) plays a significant role in providing the desired quality of service (QoS) in cellular networks. We investigate the role of pricing as an additional dimension of the call admission control process in order to efficiently and effectively control the use of wireless network resources. First, we prove that, for a given wireless network, there exists a new call arrival rat......

Communications directed by bound types in Linda: presentation and formal model
IEEE Transactions on Parallel and Distributed Systems - Tập 13 Số 8 - Trang 828-843 - 2002
Linda is an elegant parallel and distributed programming model. It is based on a shared associative memory, structured in tuples. We show that this model suffers from the false matching phenomenon. We explain under which conditions this problem occurs, we examine the solutions already proposed to solve it, and we show why they are not sufficient. In this framework, our goal is to propose an extens......

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......

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......

A study of adaptive forward error correction for wireless collaborative computing
IEEE Transactions on Parallel and Distributed Systems - Tập 13 Số 9 - Trang 936-947 - 2002
This paper addresses the problem of reliably multicasting Web resources across wireless local area networks (WLANs) in support of collaborative computing applications. An adaptive forward error correction (FEC) protocol is described, which adjusts the level of redundancy in the data stream in response to packet loss conditions. The proposed protocol is intended for use on a proxy server that suppo......

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......

Learning to classify parallel input/output access patterns
IEEE Transactions on Parallel and Distributed Systems - Tập 13 Số 8 - Trang 802-813 - 2002
Input/output performance on current parallel file systems is sensitive to a good match of application access patterns to file system capabilities. Automatic input/output access pattern classification can determine application access patterns at execution time, guiding adaptive file system policies. In this paper, we examine and compare two novel input/output access pattern classification methods b......
