QoS management is nowadays a mandatory feature in current broadband residential gateways developments. The interconnection between different QoS domains has to be treated into different steps in order to provide a reliable end-to-end QoS solution. The scenario analyzed in this paper is the mapping between QoS requirements in residential users connected to a broadband access network across a mul...

When a Mobile Ad Hoc network (MANET) is connected to the Internet, it is important for mobile nodes to detect available Internet gateway (IGW) providing access to the Internet. Gateway discovery time have strong influence on packet delay and throughput. In most of the cases, a mobile node uses minhops to the gateway to communicate a fixed host connected to an Internet. However, a minimum hop pa...

BACKGROUND The Gateway Drug Theory suggests that licit drugs, such as tobacco and alcohol, serve as a "gateway" toward the use of other, illicit drugs. However, there remains some discrepancy regarding which drug-alcohol, tobacco, or even marijuana-serves as the initial "gateway" drug subsequently leading to the use of illicit drugs such as cocaine and heroin. The purpose of this investigation ...

Imagine that a malicious hacker is trying to attack a server over the Internet and the server wants to block the attack packets as close to their point of origin as possible. However, the security gateway ahead of the source of attack is untrusted. How can the server block the attack packets through this gateway? In this paper, we introduce RemoteGate, a trustworthy mechanism for allowing any p...

WAP protocol is a set of communication protocols application environment and wireless devices. WAP model more than a WAP gateway. Suitable for wireless communication environment. Keywords-component; Wireless communications, WAP, WAP gateway, WML.

In this paper, we propose a virtual storage system based on the multiple embedded devices in IoT environments, which builds the storage by reusing the remaining storage space of the existing embedded devices. The virtual storage system consists of a client, a gateway and multiple embedded devices. The client transmits various types of data to the gateway. The gateway divides the data transmitte...

Wireless sensor networks (WSNs) often employs miniaturized battery-operated nodes. Since in most setups it is infeasible or impractical to replace the onboard energy supply, the design and operation of WSNs are subject to a great deal of optimization. Among the most popular strategies is the pursuance of multi-hop routes for forwarding collected sensor data to a gateway. In that case, the gatew...

Ad hoc networks were initially conceived as stand-alone entities without connection to any external infrastructure. A possible solution to give access to ad hoc terminals to the Internet trough conventional WLAN networks is described in the mobile multi-gateway support. This scheme proposes to utilize a mobile node within the transmission range of the WLAN access point as a connecting gateway b...

In the present existing system, only Zigbee is used as a wireless communication device to transmit the sensed data to the control room through commercial platform Zigbee. A new system is presented in which the application of WSN (Wireless Sensor Network)/Zigbee is gaining popularity and connecting WSN/Zigbee to the present standard network seamlessly is an important issue. This paper presents t...

Nowadays, research in various disciplines is enhanced via computational methods, cutting-edge technologies and diverse resources including computational infrastructures and instruments. Such infrastructures are often complex and researchers need means to conduct their research in an efficient way without getting distracted with information technology nuances. Science gateways address such deman...
