TLDR
The article considers the network layer by discussing extensions that are being made to the widely used Internet protocol (IP) to deal with mobility (wired or wireless) and speculating on future directions for wireless LAN systems.Abstract:
The emerging widespread use of wireless LAN systems together with the users' desire for such systems to interoperate has created a requirement for standards. Many standards bodies are currently defining standards for wireless systems that relate to different layers of the networking protocol stack. Of these, two influential physical and data link layer standards, IEEE 802.11 and the European HIPERLAN, are described. The article then considers the network layer by discussing extensions that are being made to the widely used Internet protocol (IP) to deal with mobility (wired or wireless). The final standards that are discussed relate to wireless link management. The article concludes by speculating on future directions for wireless LAN systems.read more

Measurements and analysis of the indoor wideband millimeter wave wireless radio channel and frequency diversity characterization
TL;DR: In this article, the performance of frequency diversity for 155 MHz and other channel bandwidths to accommodate modulated signals with data rates up to 155 Mb/s was evaluated using maximum selection combining and presented as functions of frequency separation between the diversity branch signals.

Performance evaluation of a request-tdma/cdma protocol for wireless networks
Mainak Chatterjee,Sajal K. Das +1 more
TL;DR: By simulation experiments, the request-TDMA/CDMA protocol is able to effectively combine the orthogonality of both time and code division multiplexing and further enhancements are also proposed to decrease the waiting time and increase the average channel utilization.

Indoor propagation characteristics at 5.2GHz in home and office environments
Hyun Kyu Chung,Henry L. Bertoni +1 more
TL;DR: This paper presents results of continuous wave and swept frequency response measurements over the frequency range of U-NII lower and middle bands from 5.15GHz to 5.35GHz in indoor environments and the CBW was determined from the envelope correlation.

Mobile communications network
TL;DR: In this paper, a method of transmitting one or more data streams to a mobile terminal (410) having multiple network connections is proposed, where the forwarding of the data streams is dependent upon the network connectivity data received by the home agent (430).

Book
The Theory of Error-Correcting Codes
TL;DR: This book presents an introduction to BCH Codes and Finite Fields, and methods for Combining Codes, and discusses self-dual Codes and Invariant Theory, as well as nonlinear Codes, Hadamard Matrices, Designs and the Golay Code.

Highly dynamic Destination-Sequenced Distance-Vector routing (DSDV) for mobile computers
TL;DR: The modifications address some of the previous objections to the use of Bellman-Ford, related to the poor looping properties of such algorithms in the face of broken links and the resulting time dependent nature of the interconnection topology describing the links between the Mobile hosts.
IP Mobility Support
TL;DR: This document specifies protocol enhancements that allow transparent routing of IP datagrams to mobile nodes in the Internet.
Dynamic Host Configuration Protocol
TL;DR: Due to some errors introduced into RFC 1531 in the editorial process, this memo is reissued as RFC 1541.

Mobility support in IPv6
TL;DR: This document specifies Mobile IPv6, a protocol which allows nodes to remain reachable while moving around in the IPv6 Internet, and defines a new IPv6 protocol and a new destination option.
