This paper will summarize the technologies and challenges related to wireless mesh networks. With the latest technologies in wireless LAN with WPA and 802.11i, enterprise deployments have finally begun to embrace wireless access networks. Wireless LAN technology has often been approached cautiously in enterprise deployments, partly due to well-known and easily exploitable attacks on early 802.1...

In recent years, position estimation systems using wireless LAN have been actively studied, along with the publication of many contributions. However, most of these location estimation methods require prior knowledge of wireless LAN access point locations. To deploy a location estimation system widely in the real world, it is crucial to develop an efficient pre-acquisition method of wireless LA...

A software defined radio (SDR) prototype based on a multiprocessor architecture (MPA) is developed. Software for Japanese personal handy phone system (PHS) of a 2G mobile system, and IEEE802.11 wireless LAN, which has much wider bandwidth than the 2G systems, is successfully implemented. Newly developed flexible-rate pre-/post-processor (FR-PPP) achieves the flexibility and wideband performance...

The low cost and easy deployment of Wireless LAN 802.11 standard means it becomes more and more popular, but it has a vital drawback with regard to Quality of Service (QoS). QoS defines the ability of network to introduce consistent services for data transmission, and is evaluated in terms of specific parameters such as jitter, delay, and packet loss. These parameters describe data traffic qual...

The emergence of several IEEE 802.11 Physical Layer (PHY) standards such as IEEE 802.11 a, b & g operating in the range of 2.4 GHz unlicensed Industrial Scientific Medical (ISM) and 5.8 GHz UNII frequency band may lead to delays and multi-rate shifting over a large distance in a multi-hop wireless network environment; result in significance throughput degradation when devices coexist in the wir...

A campus-wide wireless LAN has been implemented that combines the scalability of virtual LANs and the flexibility of switched Ethernet with the mobility of wireless LAN access. A suite of general-purpose software tools has been developed and deployed to monitor the status of the network, measure the bandwidth utilization, control access to the network, and authenticate users.

The number of users using wireless Local Area Network is increasing exponentially and their behavior is changing day after day. Nowadays, users of wireless LAN are using huge amount of bandwidth because of the explosive growth of some services and applications such as video sharing. This situation imposes massive pressure on the wireless LAN performance especially in term of fairness among wire...

Many corporations are seriously concerned about security of networks and therefore, their network supervisors are still reluctant to install WLANs. In this regards, the IEEE802.11i standard was developed to address the security problems, even though the mistrust of the wireless LAN technology is still existing. The thought was that the best security solutions could be found in open standards ba...

IEEE802.11s draft proposes a new medium access control (MAC) function-mesh deterministic access (MDA), which is mainly used for single-channel wireless mesh local area network (LAN). In single-channel environment, collisions between control packets and data packets may occur very often. In order to provide higher performance and network capacity for wireless mesh LAN, this article develops an a...
