An enhanced MAC architecture for multi-hop wireless networks

Abstract

The IEEE 802.11 MAC family of standards has been designed for communication in traditional wireless LANs. The enhancement of the IEEE 802.11 family of standards is mainly seen in terms of channel speeds [1][2]. This fact, combined with advances in portable/handable computing and wireless technologies are expected to further increase possibilities and significant interest in the design and development of instantly deployable, wireless networks. Its usability in multi-hop wireless networks has been discussed in several papers. Starting from several known problems and issues, and analyzing the cause of these problems, we design the architecture of an enhanced IEEE 802.11 MAC card for multi-hop wireless networks. © IFIP International Federation for Information Processing 2003.
