Locating mobile agents in a wide distributed environment
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...

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...

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...

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...

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...

Optional and responsive fine-grain locking in Internet-based collaborative 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...

Communications directed by bound types in Linda: presentation and formal model
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...

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 ...

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...
