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......

A study of adaptive forward error correction for wireless collaborative computing
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......

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 ......

Balancing buffer utilization in meshes using a "restricted area" concept
Tập 13 Số 8 - Trang 814-827 - 2002
Adaptive routing and virtual channels are used to increase routing adaptivity in wormhole-routed two-dimensional meshes. But increasing channel buffer utilization without considering even distribution of the traffic loads tends to cause congestion in the most adaptive routing area. To avoid such traffic congestion, a concept of the restricted area is proposed. The proposed restricted area, defined......

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......

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......

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......

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 ......

Observations on using genetic-algorithms for channel allocation in mobile computing
Tập 13 Số 9 - Trang 948-962 - 2002
This paper highlights the potential of using genetic algorithms to solve cellular resource allocation problems. The objective in this work is to gauge how well a GA-based channel borrower performs when compared to a greedy borrowing heuristic. This is needed to establish how suited GA-like (stochastic search) algorithms are for the solution of optimization problems in mobile computing environments......
