Multipath routing allows building and use of multiple paths for routing between a source-destination pair. It exploits the resource redundancy and diversity in the underlying network to provide benefits such as fault tolerance, load balancing, bandwidth aggregation, and improvement in QoS metrics such as delay. There are three elements to a multipath routing, namely, path discovery, traffic dis...

This paper considers a general energy harvesting cooperative network with M source-destination (SD) pairs and one relay, where the relay schedules only m user pairs for transmissions. For the special case of m = 1, the addressed scheduling problem is equivalent to relay selection for the scenario with one SD pair and M relays. In conventional cooperative networks, the max-min selection criterio...

Purpose – The tourism industry service network (TISN) is considered to be one of the largest components of tourism in the modern Vietnamese economy. The Vietnam National Administration of Tourism (VNAT) is currently developing a long-term plan to diversify the country’s tourism industry and to improve the destination image of Vietnam. To successfully implement this plan, the Vietnamese tourism ...

In this paper a relay selection scheme for amplify and forward relaying is proposed to select one relay from multi-relay networks. The selected relay by the proposed algorithm cooperates only if the signal to noise ratio (SNR) of the source-relay-destination link is greater than the SNR of the source-destination link. A theoretical bit error rate performance of the proposed scheme is derived. C...

Node cooperation is considered in this paper in the existence of two relaying protocols i.e. “Amplify and Forward (AF)” also called “Store and Forward (SF)” and the second relaying protocol is “Decode and Forward”. The two stated protocols are different from each other and perform different operations on received data before retransmitting to next hop. Also the selection of each protocol is var...

In this letter, we investigate covert communication in relay networks with selection. We consider the scenario that while forwarding source's message, selected opportunistically transmits its own message to destination covertly. derive probability of detection error (PDE) and average rate (ACR) a closed form, based on which analyse effects system parameters performance communication. Our analys...

In this paper, we propose a Cooperative Transmission Strategy using Entropy-based Relay Selection in Mobile Ad-hoc Wireless Sensor Networks (MAWSN) with Rayleigh Fading Environments. The main features and contributions of the proposed cooperative transmission strategy are as follows. First, entropy-based relay selection is used to improve data transmission reliability from a source node to a de...

Purpose This paper aims to investigate the impact of memorable destination experience and attractiveness on tourist-destination identification love. It also investigates moderating role gender. Design/methodology/approach Using cluster sampling method, study selected cities a developing country with most popular destinations. A questionnaire survey was used collect data from sample foreign dome...

there is always a meaning concealed behind functional aspects of any physical structure. this covert meaning is tranfered to the user or observer of the phenomena and forms his perception. studying the perception of the visitors towards the visited structure is considered useful in several research fields. in tourism context, visitors’ perception towards visited destination is obliged as a sign...

We present a model for inter-domain traffic engineering with end-to-end quality of service support, focusing particularly on bandwidth guarantees. We address the problem of egress router selection, which involves the selection of the egress router for customer traffic towards the destination prefixes taking into account end-to-end bandwidth constraints . We also consider performance optimisatio...
