QUALITY OF SERVICE IN VARIABLE TOPOLOGY NETWORKS

* About 25 years ago the first routing protocols that have become known as Variable Topology Routing Protocols that were not simply random routing or flooding appeared. Their objective is to maintain and continue the delivery of message traffic in a network where the topology of the network (the router connections) is variable. In recent years this has become an area of great interest with sessions at ICC, Infocom, Globecom, and Milcom, as well as papers in both IEEE and ACM Journals. There is also an Internet Engineering Task Force group studying a subset called Ad Hoc routing, which is based upon a common broadcast channel, an outgrowth of packet radio, and an active worldwide researcher mail-list. There are literally tens of new protocols proposed every quarter. There are, however, limited numbers of papers describing performance of such protocols and fewer still describing comparative performance with meaningful statistical analysis of operation (steady-state and learning modes). As such a reader/user/organization wishing to employ such a protocol has little to go on in making a selection choice. Furthermore, many methods seek only to deliver traffic but do not consider timeliness, priorities, and other features that users might desire.

Likewise quality of service is also a subject of great interest in conferences and journals as users want predictable performance. Here again there are many ideas and little to go on in terms of performance, methods of evaluation, or standards, which would allow a user to select an approach that maximizes his capacity or performance or gives guarantees of delivery performance.

It is the objective of this issue to publish papers presenting methodology, performance, comparative performance, and methods for providing/increasing user capacity and performance in variable topology networks, and quality of service alternatives, which will allow potential users to gain the necessary information to make real world implementation comparisons and choices. This performance can be shown by analysis, simulation or implementation with preference being given to papers providing comparisons of alternatives. Our goal is that there be one source for current information to aid users in the decision making process. New methodologies will be considered if they are in papers that also compare their performance to other well-known approaches and demonstrate improved value. Papers that show other methods including architectural, reconfigurable, and topological approaches and MAC features to increase user capacity and performance are also desired. But again, these papers must show comparative advances in performance.

Call for Papers

Topics of keen interest today in networking technology include methods of delivering services over variable topology networks, such as variable point-to-point and Ad Hoc networks, in which the user is mobile and inter-router connections are time varying. We seek here to gather a body of work that reports the state of the art and practice in assessment of the quality of service (QoS) that can be delivered over such networks. We specifically seek contributions that will be of value to system architects in selecting collections of technologies and methodologies that meet their needs and establish standards for user responsive system performance.

We are especially seeking contributions that report QoS delivery in clearly defined network settings under clearly defined metrics for a specific service or collection of services. Such contributions might focus specifically on comparing alternative technological or methodological approaches to delivering services with quality guarantee, such as bi-directional versus unidirectional connectivity, source-based versus dynamic routing, proactive versus reactive organization, transmission control at the transport layer versus the MAC layer, retransmission versus forward error correction and the relation of these to timeliness and priority. Variable topology peer-to-peer and Ad Hoc constructions in both flat and hierarchical environments are of interest.

Alternatively, a contribution might focus on the performance that can be achieved using a single technological and methodological approach, but varying key factors of interest, such as the number of end systems, end-system density, or the delivery physical environment. Throughout, the central theme should be service delivery, and the metrics used should enable potential users to clearly see patterns of performance in one or more of the following dimensions: cost, complexity, timely delivery, traffic handling capacity, or the number of end systems the system can handle. Methods for achieving quality of service under conditions of varying topology, and new concepts for providing quality of service are likewise of interest.

In this context, the topics for this issue include:

The call for papers is for extended abstracts that propose development of papers to meet the goals of the issue. The proposal shall comprehensively describe the area of the paper relative to the areas of interest of the call. These extended abstracts will be reviewed and the editors will invite final papers, which will be refereed. Extended abstracts not to exceed 5 pages in .pdf format should be submitted by April 1, 2003. To submit your extended abstract 1) go to http://edas.cs.columbia.edu http://edas.cs.columbia.edu/, 2) establish an account, 3) receive an e-mail from edas with your password, 4) login to the edas system, 5) select the J-SAC issue, 6) click on view, 7) click on submit paper and follow the instructions. Upon invitation papers should be submitted in .pdf format. Papers should follow the IEEE J-SAC manuscript format described in the Information for Authors http://www.argreenhouse.com/society/J-SAC/Guidelines/info.html, and be no longer than 25 double-spaced pages, excluding illustrations and graphs.

The name of the submitted file should be aaaaJsacVtn.pdf, where aaaa is the first four letters of the author's surname. If an author submits more than one paper then aaaa shall be replaced by aaaan where n is a sequential paper number (e.g. 1, 2, ...). All submissions must be electronically generated. Scanned documents are not acceptable.
