The spread of subject gateway sites can have an impact on the other major Web information retrieval tool: the commercial search engine. This is because gateway sites perturb the link structure of the Web, something used to rank matches in search engine results pages. The success of Google means that its PageRank algorithm for ranking the importance of Web pages is an object of particular intere...

This article put forward a method to realize the transmission between wireless sensor network and the Internet. The IOT (Internet of Things) gateway is used as part of the greenhouse monitoring system. The design compatible multiple access method such as LAN, Wifi, GPRS, EDGE, 3G and so on, also the data can stored locally. The IOT gateway uses STM32 as the MCU, μC/OS-III as the embedded operat...

In this paper we present the architecture of an application level fax-Internet gateway, and show how such a gateway could be utilised to facilitate multimedia messaging and to extend Internet services to the home or office. We propose the application of the latest developments in the facsimile and Internet worlds, notably MIME and BFT support for G3 protocols, for the exchange of multimedia mes...

The key design idea underlying the Wireless Application Protocol (WAP) is to use a gateway at the intersection of the wireless mobile network and the traditional, wired network. The WAP gateway forwards web content to the mobile phone in a way intended to accommodate the limited bandwidth of the mobile network and the mobile phone’s limited processing capability. However, the gateway introduces...

This thesis proposes, describes and validates solutions to enhance mobility in heterogeneous access networks. Wireless access networks have become available almost everywhere and current research strives to make them pervasive. Users having wireless access to the Internet are driving the demand for mobile and heterogeneous solutions where services could be accessed from anywhere, any time and f...

BACKGROUND Employing genomic DNA clones to characterise gene attributes has several advantages over the use of cDNA clones, including the presence of native transcription and translation regulatory sequences as well as a representation of the complete repertoire of potential splice variants encoded by the gene. However, working with genomic DNA clones has traditionally been tedious due to their...

A typical ship area network provides wired instrument network connections and shipboard control networks. However, the need for high-speed data transmission services of instrument-to-instrument and machine-to-machine is essential for a high-cost valued digital ship. Thus, this paper proposes IEEE 802.15.3 based CSMA/CA high-rate wireless personal area network (HRWPAN) wireless gateway applicati...

RADIUS specified by RFC2865 and RFC2866 is used widely for remote dial-in user authentication and authorization. Packet filter such as Linux Netfilter is a primary toolkit to develop firewall or intrusion detection system. Modeling RADIUS client and packet filter together, a security gateway for grid computing is developed as an embedded or a proxy system. To reinforce the flexibility of the ga...

The growth of network intensive Internet applications has made gateway congestion control a high priority. The IETF Performance and Congestion Control Working Group surveyed and reviewed gateway congestion control and avoidance approaches. The purpose of this paper is to present our review of the congestion control approaches, as a way of encouraging new discussion and experimentation. Included...

This paper presents the architecture and design of an enhanced VoIP gateway, which is based on the H.323 protocol. The key characteristics of this gateway include: scalability separating signaling from media transformation and use of protocols such as MGCP/MEGACO for the communication between signaling part and media gateway; lightweight by using SCTP transport protocol to convey H.323 and MGCP...
