Texte intégralThe usage of Wireless Local Area Networks is increasing rapidly throughout the world. The technology today is not quality proof for the market’s demands. We want to be able to completely wireless perform our demands, such as confer via video or IP-telephony. This is what we call multimedia real-time traffic. It may be achieved over the physical infrastructure in some areas with good results. The goal of this Master’s Thesis is to analyze the possibilities and give solutions and suggestions to achieve multimedia over the wireless networks, with emphasis on the protocol Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA).
This Master’s Thesis is a theoretical study and the suggested solutions have not been tested in an actual wireless network. Instead they have been tested by computer simulation to give an indication of improvements. Basic configurations are set to the same as in the IEEE 802.11 standard.
Different methods to reach possible improvements of a WLAN are studied, analyzed and simulated. Such methods are: priority, congestion management and multi-channel protocol. Simulations results show how the priority affects the wireless network and how a multi-channel protocol improves the latency and efficiency of the network. The simulation part is concentrated to show improvements of real-time traffic, which is time sensitive. With a multi- channel protocol the network can allow more users, i.e. more traffic. Also, the network will gain improvement in stability.

Texte intégralOn the modern battlefield, successful and fast communications is a critical issue. So the need for transmitting information in larger amounts through a military high-speed network increases. Thus the military is seeking viable and effective solutions that may fulfill these requirements in an operational environment. This thesis develops a prototype system based on appropriate low-cost software and hardware solutions. This system is able to detect, analyze and process wireless 802.11g signals. The evaluation of the newly designed system proved that it is effective up to distances of about 400 m with a low packet error rate and could be a useful tool for detecting wireless 802.11g networks. After evaluating the system, it was used for capturing wireless signals so that we would determine the effective transmission range and the data throughput of an 802.11g network. We determined that such a wireless network could be used in military operations because it offers high data rates up to 200 m, while it maintains a connection of the wireless clients for distances up to 400 m. In addition, the performance data collected can be used as guidelines for estimating the expected performance in an operational situation and can provide useful information for successful planning.

Texte intégralNomadic Computing har för avsikt att revolutionera dagens Internet tillämpningar. För att lyckas måste dock infrastrukturen, IT protokollen och handoff procedurer utformas och implementeras med intentionen att förse mobilt dataöverföring med både driftsäkerhet och autonoma processer. En stor del av de nödvändiga förutsättningarna är tillgängliga tack vare Mobile IP, men mångfalden inom de befintliga Wireless teknologierna utgör fortfarande ett problem. Det stora antalet disponibla Wireless tekniker varierar från teknologierer som förser användaren med en stor täckningsgrad, till sådana som förser användaren med högre bandbredd, begränsad till lokala anv ändningområden. Även Uni-directional ad-hoc links kan läggas i denna lista av mångfald. För att förverkliga fördelarna med den tänkta infrastrukturen fullt ut måste den mobila enheten kunna utföra omkopplingar från den ena wireless teknologin till den andra, med syftet att vara osynlig för användaren. Utöver detta är det meningen att en apparat med många anslutningar ska kunna välja den anslutning som passar bäst, var gång en ny koppling ska göras, beroende på den tjänst som efterfrågas. Det här examensarbetet presenterar en möjlig lösning, som utnyttjar både Vertical Handoff optimering och Policy Management. Prototyp-enheten vi anv änder oss av för att genomföra undersökningen är Smart Badge v4, utrustad med GPRS och 802.11b Wireless LAN anslutningar.

IEEE 802.11 provides high bandwidth connectivity in a local area network (LAN) environment that is suitable for most data applications but it does not meet the quality of service (QoS) requirements for real-time data traffic applications such as voice, audio and video transmissions. There have been recent proposals on enhancements to the IEEE 802.11 Medium access control (MAC) protocol to provide expedited access to the shared wireless network for real-time data transmissions. We propose the combined use of traffic flow control and burst control and expedited transmission of higher priority data over the shared wireless network as the mechanisms to provide QoS guarantee for real-time application data traffic in IEEE 802.11 Wireless LANs.

IEEE 802.11 wireless local area networks (WLANs) can be built in one of two modes: ad-hoc mode and infrastructure mode. In the infrastructure mode, an access point (AP) is required to act as a bridge by which mobile nodes can communicate with each other or connect to wired networks. The cell size of a WLAN is usually small. Besides, a mobile node will make an association with an AP nearest to the node. Therefore, it is practical to develop location-based services based upon the awareness of the WLAN AP that mobile nodes currently access. In this thesis, we will discuss how to develop location-based push services in WLANs. It will be shown that the location of a mobile client can be determined effectively through an SNMP Trap approach. When a mobile node makes an association with an AP, the AP will send an SNMP trap to its management station. The MAC address of the mobile node will be presented in the trap. Therefore, the current location of the mobile node can be determined by knowing the location of the AP. To further deliver location-based information to the mobile node, we also have to know the current IP address of the mobile node. Therefore, the SNMP Trap approach will also involve an effective address mapping scheme to find the IP address of a mobile node from its MAC address. In this thesis, we will also develop a location-based push service framework to enable the delivery of location dependent push messages to all mobile nodes within a specific area. In addition, the framework also allows the delivery of instant location dependent push messages to a mobile node immediately after the mobile node roams into a specific area. The proposed location-based push service framework is a generic one for most location-based push services. Based on the framework, we will also develop a personalized advertising application to verify the soundness of the framework.
