In this paper, we discuss a peer-to-peer (P2P) model of a topic-based publish/subscribe (PS) system (P2PPS model) where each peer process (peer) can both subscribe and publish event messages with topics and there is no centralized coordinator. Each peer has to causally deliver event messages in which the peer is interested. In our previous studies, the TBC (topic-based causally delivery) protocol...
Simulation is a common method used to examine the models and protocols before they are implemented in real systems. Vehicular networks present different characteristics which render most of their simulations inapplicable to real-world Vehicular Ad Hoc Networks. In these days, the important advancement has been made toward the realistic simulators. OMNeT++, SUMO, and Veins provide a decent way for...
Software Defined Networks provide the ability to manage networks from a centralised point through separating control plane from the data plane. This brings opportunities in terms of manageability, flexibility and cost savings in network operations. This centralisation, however, also brings about a potentially serious performance bottleneck and poses a scalability issue in high performance networks...
LTE is a 3GPP full IP-based standard for wireless transmission systems. Due to its characteristic of high throughput, an efficient end-to-end QoS treatment is needed in order to guarantee good quality perceived by end users. LTE provides a native QoS-aware mechanism for end-to-end service delivering based on EPS bearer and QCI. Customers today may choose mobile services among different competing network...
Recently, Delay / Disruption / Disconnection Tolerant Networking (DTN) which aims to enable communication under poor communication environments has been attracting attention. In DTN, direct communications among nodes are performed and messages of a node are replicated among nodes. This operation is repeated until a message is arrived at a destination node. Therefore, it is important to decide replication...
