An efficient synchronization scheme of multimedia streams in wireless and mobile 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...

Data gathering algorithms in sensor networks using energy metrics
Tập 13 Số 9 - Trang 924-935 - 2002
Gathering sensed information in an energy efficient manner is critical to
operating the sensor network for a long period of time. The LEACH protocol
presented by Heinzelman et al. (2000) is an elegant solution where clusters are
formed to fuse data before transmitting to the base station. In this paper, we
present an improved scheme, called PEGASIS (power-efficient gathering in sensor
information ...

Addressing and routing in hexagonal networks with applications for tracking mobile users and connection rerouting in cellular networks
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...

Extended dominating-set-based routing in ad hoc wireless networks with unidirectional links
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 ...

Integration of pricing with call admission control to meet QoS requirements in cellular networks
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...

Adaptive bandwidth reservation and admission control in QoS-sensitive cellular networks
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
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...

Learning to classify parallel input/output access patterns
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...

On the asymptotical optimality of multilayered decentralized consensus protocol
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 ...

On load balancing for distributed multiagent computing
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...
