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...

The last few years have seen lot of work for providing network connectivity in remote rural areas. An alternative of wired network has been to use off the shelf 802.11 equipment with high gain antennas to provide network connectivity to rural areas. The attractiveness of this setting comes from cost effectiveness and low power consumption. Althougth there are many such network deployments, a ve...

This paper considers the realization of fiber-wireless (Fi-Wi) networks using the gigabits passive optical network (GPON) and the infrastructure-based wireless local area network (WLAN). The bottleneck of such hybrid system is the WLAN where interference limits the performance. As such, we focus on enhancing the WLAN performance by analytically deriving the optimum contention window (CW) sizes ...

New deployment scenarios tend to consider the requirement of session continuity for service provisioning, especially multimedia streaming, to limited heterogeneous portable devices roaming among wireless localities. In particular, multimedia streaming should not experience any interruption while clients roam in wired-wireless integrated networks based on the standard besteffort Internet. The pa...

Wi-Fi Direct is a popular wireless technology which is integrated in most of today’s smartphones and tablets. This technology allows a set of devices to dynamically negotiate and select a group owner which plays the role access point. This important feature is the strength of Wi-Fi Direct and makes it more and more widely used in telecommunications networks. In this paper, we present the implem...

Over the past few years, we have witnessed a growing popularity of new wireless architectures such as 3G, Wi-Fi and Wi-Max due to the increase in demand for wireless Internet access. The all-IP based future mobile and wireless network model is expected to be the most dominant architecture for QoS provisioning in next-generation wireless networks, mainly due to its scalability and capability of ...

As wireless services have become increasingly integrated and their demand is mounting, Wi-Fi provides an appealing opportunity for the GSM/GPRS operators to enhance their data capability. By integrating both networks, operators are able to provide 3G-like services. However, both networks have different data rates and capacity, which makes pricing a challenging issue. In this paper we propose a ...

The Software-Defined Networking (SDN) paradigm is one that utilized frequently in data centers. Wireless Networking, often known as SDWN, refers to an environment which concepts from SDN are implemented wireless networks. SDWN struggling with challenges of scalability and performance a result the growing number networks its coverage area. It thought techniques, such Mininet-Wi-Fi Ryu Controller...

The 4th Generation (4G) wireless mobile internet networks will be combined through current existing cellular networks (i.e., CDMA2000, WCDMA and TD_SCDMA) and Wi-Fi (i.e., Wireless LAN) networks with fixed internet to support wireless mobile internet as the same quality of service as fixed internet. Each of the networks has own specified protocols, disparity frequency, and maximum data speed an...
