WiFi networks, which have been widely used along with the explosive increases in the supply of smartphones, can provide high network speeds but cannot prevent user information spills though rogue Access Points (APs). Therefore, the present paper proposes a method to exchange SSL session keys through more secure 3G networks to be used in WiFi networks in order to prevent such spills. In the prop...

Recently, network researchers have taken a great interest in quality of experience (QoE) and in the new aspects it brings in the study of the link between network conditions and user satisfaction. Also, the realization that the information of users’ satisfaction can be directly applied in the network management in a real-time manner has resulted in a fair amount of publications. Although the sy...

Mobile Data Mining focuses on finding useful knowledge out from raw data from mobile users. In this paper, parallel pattern is proposed, which describes the movement trend patterns of mobile users. Parallel pattern aims to find out the trend of movement based on physical location as detected by the wireless access point. The performance testing of this paper shows that as the number of differen...

This paper discusses how ad-hoc Personal Area Network (PAN) based on Bluetooth technology may connect to external networks. We assume that the Bluetooth network (piconet) is formed by the automatic SAPIFO procedure [4], that one or more piconet devices have access to external networks, and that IPv4 is used for external communication. Bluetooth have specified a PAN profile[2] for IP over Blueto...

The most common measures so far to reduce the digital divide has been the development of telecentres (Internet public access points) that provide Internet access and specific training. However, the extremely poor very rarely enter the telecentres. In this paper, we propose a more specific approach suited to this population. We first describe the social-digital exclusion process facing the extre...

Cities around the world are currently considering building expensive Wi-Fi infrastructure. In urban areas, resident operated Wi-Fi access points (APs) are dense enough to achieve ubiquitous Internet access, provided we can induce the hosts to provide guest Wi-Fi access. However, sharing Wi-Fi involves taking on responsibility for the guest’s actions. Our main contribution is a novel mechanism t...

Wireless sensor networks (WSNs) possess diverse traffic due to different monitoring tasks carried out by sensor nodes. Meanwhile, in energy harvesting WSNs, the main goal is to match energy consumption with the energy harvesting rate which is different from minimizing energy consumption in battery-powered WSNs. We propose a dynamic adaptive medium access control (MAC) algorithm in energy harves...

In an intermittently connected environment, access points are sparsely distributed throughout an area. As mobile users travel along the roadway, they can opportunistically connect, albeit temporarily, to roadside 802.11 (Wi-Fi) APs for Internet access. Networking characteristics of vehicular Internet access in an intermittently connected environment face numerous challenges, such as short perio...
