We present a P2P scheme that could fuel the deployment of free public wireless LANs (WLANs) in cities; these WLANs would complement existing and future cellular networks. We call our scheme the P2P Wireless Network Confederation (P2PWNC). Unlike existing approaches, P2PWNC does not rely on central planning or altruistic groups. In P2PWNC, wireless service is provided to those who provide servic...

Today’s access point based wireless LANs (WLANs) are inefficient and unfair. For many traffic loads they provide far less total throughput than they should, and do a poor job allocating what throughput they do deliver. Inappropriate association of nodes to access points and rates to flows plays a large role in these problems. We address a major root cause of this problem in this paper. Current ...

The paper provides an overview of the application scenarios and modelling issues of Wireless Local Area Networks (WLAN) in hospital and clinical ward environments and presents the concept of MedLAN system, dedicated to these environments. Furthermore, it discusses the potential problems when implementing such systems.

When the wireless communications is coming to the offices and the homes, there are some new security issues to be taken care of. Today we have continuously growing markets for the wireless LANs, but there is big black hole in the security of this kind of networks. This paper gives an overview of the security functions specified in two wireless LAN standard, namely in the IEEE 802.11 and the HIP...

This article discusses the problems that arise when standard Internet protocols such as TCP are used over wireless links. We review wireless link characteristics with case studies drawn from commercial Wireless LANs and Cellular Telephony systems. We discuss problems with Internet protocols when employed over these systems, such as degraded TCP performance when wireless errors are interpreted a...

Wireless LANs (WLANs) and Wireless Sensor Networks (WSNs) are two large groups of networks that have well established application ranges. Despite the fact that they address very distinctive groups of devices and have clearly differentiated wireless interfaces, there are certain similarities which push scientists to look for adopting solutions already designed for WLANs to WSNs. An example of th...
