One challenge of wireless networks integration is the ubiquitous wireless access abilities which provide the seamless handover for any moving communication device between different types of technologies (3GPP and non-3GPP) such as Global System for Mobile Communication (GSM), Wireless Fidelity (Wi-Fi), Worldwide Interoperability for Microwave Access (WiMAX), Universal Mobile Telecommunications ...

Heterogeneous small cell networks (HetSNet) comprise several low power, low cost (SBSa), (D2D) enabled links wireless-fidelity (Wi-Fi) access points (APs) to support the existing macrocell infrastructure, decrease over the air signaling and energy consumption, and increase network capacity, data rate and coverage. This paper presents an active user dependent path loss (PL) based traffic offload...

Android devices are portable, equipped with powerful processors, and can act as both mesh routers and clients through Wi-Fi Direct, making them a suitable platform from which to deploy a wireless mesh network. To allow Android devices to automatically establish and participate in a wireless mesh network, we circumvent two key problems of the Android’s Wi-Fi APIs: lack of direct support for ad-h...

This paper studies the use of wireless Ethernet (Wi-Fi) as a localization sensor for mobile robots. Wi-Fi-based localization relies on the existence of one or more Wi-Fi devices in the environment to act as beacons, and uses signal strength information from those beacons to localize the robot. Through the experiments described in this paper, we explore the general properties of Wi-Fi in indoor ...

Abstract The most flexible and reliable technological system is Wi-Fi, which made possible by a wireless connection that transmits data using radio frequencies. Wi-Fi networks, however, encounter numerous issues related to power supply, availability, efficiency, security as result of the various access points. While relational waves describe medical device, radios produce are very dangerous for...

The development of integrating several wireless network technology make wireless network devices built everywhere. In 1999, IEEE proposes WiMAX broadband wireless technology which has high transmission bandwidth and wide coverage. There are more and more researches as abovementioned wireless technology to increase Mesh network technology which can easily increase network coverage. Intel[1] poin...

Carrier Wi-Fi deployments are helping mobile operators take advantage of already deployed evolved packet core (EPC)-based services for supporting trusted Wi-Fi access networks. Approaches include reusing P-GW -based accounting, policy enforcement, and regulatory services for supporting Wi-Fi users. With Wi-Fi calling, similar EPC-based services can be used to support IMS-based rich media servic...

All automobile manufacturers continue to incorporate more and more technological features into their vehicles. One of the features is wireless access. A Vehicular Ad-Hoc Network or VANET is a technology that uses moving vehicles as nodes in a network to create a mobile network. VANET turns every participating vehicle into a wireless router or node. Some measurement studies have previously been ...

Wireless local area networks (LANs) based on the IEEE 802.11 standard [1] have been deployed extensively in recent years for both indoor and outdoor applications. The proliferation of 802.11 wireless fidelity (Wi-Fi) enabled devices such as laptops, personal digital assistants (PDAs), smart phones, cell phones, and access points is reflected by semiconductor shipments data. During 2006, almost ...
