We discuss the division of radio resources in the time and frequency domains for wireless local area network (WLAN) devices powered with microwave energy. In general, there are two ways to avoid microwave power transmission (MPT) from influencing data communications: adjacent channel operation of continuous MPT and WLAN data transmission and co-channel operation of intermittent MPT and WLAN dat...

In this paper, we propose internetworking strategy of WLAN and MANET. Both WLAN and MANET are based on IEEE 802.11 for MAC layer protocol while they adopt different mode, such as infrastructure and ad-hoc. To support internetworking between different IEEE 802.11 modes, switching algorithm on mobile node is proposed. This algorithm is mainly affected by user’s preference, not only by signal stre...

In this paper analysis and performance of AODV, DSR, GRP and OLSR is done for 1 mbps data rate. We used OPNET Simulation tool we created a network containing 30 mobile nodes with data rate 1 Mbps with transmission power 0.005 watts and buffer size 1024000 bits each node moves randomly in the network and simulation time was 1500 sec. Routing protocols are compared in terms of WLAN Load, WLAN Med...

The main methods used to implement WLAN-3G inter working are: the mobile IP methods, the emulator method, and the gateway method. Each one of these methods enjoys some pros and suffers from some cons. In this paper, It is demonstrated to evaluate certain aspects of WLAN-3G inter working. Here, case studies are addressed: based on results of the current researches and some simulations developed ...

Wireless indoor positioning has been a popular research topic for years because it provides the basis for a broad domain of location-based applications. Especially the usage of WLAN (Wireless Local Area Network) technology is widespread to build an indoor positioning system due to the reuse of existing and almost ubiquitous WLAN infrastructure worldwide lowering the costs. However, these WLAN s...

The disruptive potential of WLAN technologies is further explored in an empirical study of the German hotspot market 2003-2006. The main proposition to be checked – whether WLAN has disruptive potential for MNOs or not, suggested by Hüsig et al. (2003, 2005) or Christensen et al. (2004) – is analysed using market and firm data from the hotspot market in Germany 2003-2006. The results of our stu...

Wireless LAN (WLAN) is a recent technology that has not been extensively studied in IS research discipline. The only available literature is mostly vendor reports that glorify the success story of WLAN implementation. The current study attempts to fill this gap by undertaking a qualitative case study approach to investigate important WLAN adoption factors. Based on technology adoption construct...

Although Wireless Local Area Networks (WLANs) are widely used in many settings little work has been done in studying their impact and benefits. This study provides empirical indicators on the performance of the WLANs implemented on Malaysian Institutions of Higher Learning Our research adopted Deming’s P-D-C-A Model and modified it to PlanImplement-Control-Evaluate (P-I-C-E) in establishing a p...

This paper studies mobility in wireless LAN (WLAN, IEEE802.11). Mobility is an instinct nature of WLAN as being wireless. But this mobility is limited by radio propagation and the IEEE802.11 specifications. For seamless mobility in a larger area, e.g., between two extended service sets (ESSs), some sorts of mobility management mechanisms are needed. Mobile IP has been widely considered as a sol...

Wireless Local Area Network (WLAN) is susceptible to security provisioning in spite of the solutions such as the Wired Equivalent Protocol (WEP) or IEEE 802.1x. This paper proposes an integrated scheme for intrusion detection in WLAN systems. The proposed scheme operates with one or more Gathering Agents (GAs) and a Master Server (MS). Each GA is used to get security information by collecting t...
