In this paper, we propose a new preemptive scheme with release message in optical burst switching (OBS) networks. In the proposed scheme, when a low priority burst is preempted at some intermediate node, two RELEASE messages are sent immediately from the intermediate node to both source and destination nodes (two-way release message transmission), and the RELEASE messages release the correspond...

In this paper, we formulate relay selection into a Chinese restaurant game. A secure relay selection strategy is proposed for a wireless network, where multiple source nodes send messages to their destination nodes via several relay nodes, which have different processing and transmission capabilities as well as security properties. The relay selection utilizes a learning-based algorithm for the...

In this work, a cognitive relay network (CRN) with interference constraint from the primary user (PU) mobile end is studied. The proposed system model employs half-duplex transmission between single PU and secondary (SU). addition, an amplify forward (AF) relaying technique employed SU source destination. context, (SU destination) assumed to move at high vehicular speeds, whereas other nodes So...

The performance of dual-hop Decode-and-Forward relaying with relay selection (RS) is analyzed over Nakagamifading channels. Assuming that the direct source-to-destination link is active, closed-form expressions for the moment generating and the cumulative distribution functions of a RS-based cooperation scheme that utilizes maximal-ratio diversity at the destination are derived. These expressio...

Security and protection demands in tourism industry are very high due to the vulnerability of its infrastructure in light of security challenges and threats. Actual threats appear in the form of endangering the values that compose a train of products and services in tourism – from the moment of buying/selling a package tour, transfer of passengers and luggage to their destination, to stay in ho...

We analyze the packet delivery performance of wireless cooperative relaying in an interference limited scenario, by means of stochastic geometry. We show that the temporal and spatial characteristics of interference play a significant role in shaping the system performance. In particular, when interference has high temporal and spatial dependence, the packet delivery probability increases for h...
