Introduction

The Internet Architecture Board held a workshop on Wireless Internetworking on February 29-March 2, 2000. The goal of the workshop was to insure that the Internet Protocols are suitable for the wireless environment. The workshop was organized by Bob Hinden and held at Nokia’s Mountain View, California, US facility.



Overview

Wireless devices with internet capabilities are expected to be deployed in very large numbers in the next five years. It is likely that in this time period there may be more wireless internet devices than the current type internet devices such as PC’s. This trend will have a large effect on the Internet. It is important to make sure that the internet protocols (IP through Applications) are suitable for these devices. This workshop will provide an opportunity to examine the issues related to wireless IP and determine what work should be done.

Several types of wireless networks that will be deployed in large numbers will be discussed. They represent three categories: wide area, local area, and limited area. These are:

  • GPRS Cellular
  • IEEE 802.11
  • Bluetooth

Issues to be examined relating to running IP over wireless include:

  • Bandwidth scarcity
  • Error rates
  • Connectivity
  • Autoconfiguration
  • Routing / Discovery
  • Privacy and Authentication
  • Transport issues
  • Realtime vs. non-realtime
  • QOS
  • Transport error detection
  • Hidden terminal problem
  • Mobile IP
  • Address allocation / assignment
  • VoIP Requirements
  • Application support in wireless environment

Another important goal of the workshop is to look at the Wireless Application Protocol (WAP). WAP is currently being deployed in very large numbers. It is complementary to IP at best. Issues to be investigated include:

  • Can IP provide all of what WAP promises?
  • Can IP coexist w/ WAP?
  • Transition from WAP to IP?

The meeting will produce two types of output. The first is joint education between the IP and wireless communities. This should serve to have each group better informed about the other. The second is specific actions that the IETF should doing. This is expected to be a combination of work items for existing working groups and new working groups that should be created. Also, a meeting report will be written that describes the meeting and it’s conclusions.
