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...... hiện toàn bộ

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 ...... hiện toàn bộ

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...... hiện toàn bộ

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...... hiện toàn bộ

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...... hiện toàn bộ

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...... hiện toàn bộ

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...... hiện toàn bộ

An efficient parallel algorithm for the efficient domination problem on distance-hereditary graphs
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

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...... hiện toàn bộ

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...... hiện toàn bộ
