Technical Description

Our basic understanding of Internet characteristics and behaviors is a key foundational component upon which new technologies will be developed. An important means for expanding the basic knowledge of how the Internet functions is through the application of mathematical, statistical and analytical techniques that lend themselves naturally to specific problem domains. The difficulty in this regard is that it is rarely the case that one can simply grab a technique "turn the crank" and get results that are either correct or meaningful. Most methods have nuance in their application that is only understood within community that developed them. Conversely, it is often difficult for experts in specific analytical domains to identify or address Internetworking problems that are important.

The motivation for the first Workshop on Internet Signal Processing (WISP) is the emergence of new and powerful signal processing (SP) and multiresolution analysis (MRA) techniques in the networking domain. It is becoming increasingly apparent that SP/MRA-based or related techniques could lead to advances in network tomography, network data collection, data dimensionality reduction, data compression, traffic analysis in wired, ad-hoc wireless, and sensor networks, and network anomaly/intrusion detection. This workshop is specifically interested in new analysis techniques and approaches that are motivated by and account for the increasing availability of spatio-temporal network measurements from infrastructures such as PlanetLab and the Abilene Observatory.

The goal of WISP is to shine light on the opportunities for analysis of spatio-temporal network data and to foster discussion between network researchers and groups from the traditional signal processing, statistics and applied mathematics areas. To that end, the technical focus of the workshop will feature:

  • Application of a range of signal analysis methods in the acquisition and evaluation of Internet behavior and performance
  • Advances in signal processing and related areas
  • Advances in applied mathematics specific to multiresolution analysis
  • Advances in statistical analysis techniques
  • Emerging communication and computing technologies over wireless, optical and quantum media


Attendance at WISP will be limited to invitee's, authors of original papers and students applicants. The total number is projected to be between 40 and 50.


The organizers of WISP gratefully acknowledge the support of our sponsors, Cisco and NSF.

We will seek ACM cooperative status in order to take advantage of the ACM digital library. We will seek funding for attendees through NSF and from industrial sources.
