Commercial community wireless networks usually rely on wireless donors to give away Internet access while at home in exchange for access while they are mobile. The donors who make up the network get nothing immediate in return for providing Internet access. In this paper, we explore automatic configuration for a model of community networks in which donors mesh with each other and can aggregate Internet...
Evil Twin Attack (ETA) refers to a rogue Wi-Fi Access Point (AP) that appears to be a legitimate one but actually has been set up to eavesdrop on wireless communications [1]. Most of existing detection techniques assume that the attacker will use the same legitimate wireless network gateway to pass through victim's wireless data. These detection methods will fail if the attacker uses a different gateway,...
With Internet of Things (IoT) vision, computing systems get the ubiquity of real world. Wireless Sensor Network (WSN) technology plays a critical role for the construction of this paradigm. Reliable communication between WSN nodes and outside Internet entities will be needed for remote management of Internet Objects. On the other hand, low bandwith, high delay and packet error rates of the underlying...
In this paper, a gateway system between the wireless sensor network (WSN) and TCP/IP is designed for home automation applications. The fundamental components of this system are switches connected to WSN, the gateway between WSN and TCP/IP and a user interface program which can be used to show incoming and outgoing data to the users. The switch units are the end-devices of the WSN. There are WSN and...
Wireless mesh network (WMN) forms a wireless backbone which extend the coverage area via multi-hop relay function. The performance of WMNs can be further boosted by employing multiple gateways. In this paper, we address the implementation issues for deploying WMN test bed with multiple gateways and propose a channel load aware airtime(CL_AIR) metric based path and gateway selection scheme to balance...
Many wireless systems used by military ground personnel are satellite based. This paper explores a hybrid system that benefits from both satellite and terrestrial wireless technologies while overcoming the limitations of each. We present the architecture, describe the merits, and then explain the essence of the system: IP Flow mobility. After introducing this concept, we describe some of the important...
In this paper we consider mobility in a network of converged small-cell gateways, each capable of aggregating cellular and unlicensed bandwidth by combining a WiFi AP and a cellular base station within a single-box. A network of such gateways must provide mobility services in a decentralized fashion and we demonstrate how this may be accomplished by taking advantage of Proxy Mobile IPv6 (PMIP) - the...
One of the important challenges in the Internet of Things (IoT) is how to acquire the physical context of things. IP-based wireless sensor networks (IP-WSNs) could be a promising approach to collecting the physical context of things and to integrating WSNs to the Internet. However, realizing IP-WSNs in IoT exposes two major challenges. One is how to embed the Internet Protocol (IP) in resource-constrained...
This paper proposes an implementation of IEEE 802.21 MIH (Media Independent Handover) in Linux kernel space for cognitive and smart handovers. In the proposed scheme, the surrounding wireless access network information is collected and provided by IEEE 802.21 MIH, and the mobile node (MN) performs time-limited smart scanning with interleaved packet delivery for target access point. For better performance,...
Spurred by the increasing demand for mobile broadband services and the growing number of devices supporting multiple radio access technologies (e.g., cellular, WiMAX, Wi-Fi, Bluetooth), much research is being done to improve the user experience while addressing issues related to network efficiency, congestion, interference, and cost to operators, service providers, manufacturers, and consumers alike...
Mobility in a wireless heterogeneous scenario in which the mobile devices are able to connect to more than one access technology available in their vicinity requires a re-consideration on the access network reselection mechanisms. The present paper describes and evaluates the opportunity of introducing novel access reselection procedures which enable a network provider to optimize the allocation of...
Because of the lower bandwidth of mobile network and constrained resource of mobile terminals, the downloading file speed on mobile terminals is slow. Even in 3G networks, the downloading speed still needs to be improved. This paper proposed a HPMM (Hybrid Protocol with Multi-Thread over Multi-Gateway) solution to increase the downloading speed on mobile terminals.
Wireless home networks are extending beyond phones and computers to include every imaginable type of electronic device from TVs and audio components, to appliances and thermostats. The benefits include distribution of multimedia throughout the home, energy savings through remote or automatic control, and reduced cost through packaged services. Though people are often enamored by the technology that...
Release-8 (Rel-8) EPS (Evolved Packet System) introduced a multi access 3GPP system where different heterogeneous access systems are connected to a common core network. However, in the system, the subscriber cannot communicate using multiple accesses simultaneously. Mobile devices with multiple interfaces are becoming commonly available and the set of applications running on the devices is diversifying...
Most mobile devices are now Bluetooth-enabled. This wireless technology makes it possible to transfer files or stream contents between pieces of equipment. The possibly many devices that are in reach of each other and thus connected constitute a Personal Area Network (PAN). The problem remains that because of radio range setting up such connections is only possible for devices in a limited area. This...
Wireless Service Providers want to introduce compelling new services that rapidly generate revenue - starting with seamless voice convergence. Seamless voice convergence gained a lot of momentum in the Service Provider industry. Seamless voice convergence is enabled through the interworking of cellular service and Wi-Fi domains. This converged voice service, or Dual Mode Service (DMS), which allows...
A scheme that exploits the broadcast nature of the wireless communication in order to achieve multicast content delivery is presented in this paper. As opposed to broadcasting, this method enables the clients to determine on-line the delivered content, and thus preserves the advantages of an individual service. On the other hand, a multicast content delivery is much more efficient than a unicast content...
