Efficient routing is one of the key challenges for next generation vehicular networks for providing fast and reliable communication in a smart city context. Various routing protocols have been proposed for determining optimal routing paths in highly dynamic topologies. However, it is the dilemma of those kinds of networks that good paths are used intensively, resulting in congestion and path quality...
DTN (Delay/Disruption Tolerant Networking) inserts a new layer between the application layer (L7) and the transport layer (L4) for reliable communication on long-delay, intermittent, or lossy inks. Such a new layer, however, should provide not only a single rich service but also various rich services. We are proposing Layer-5 (L5) inserted between L7 and L4 to provide multiple rich services. One of...
Distributed overlay-based publish/subscribe systems provide a selective, scalable, and decentralized approach to data dissemination. Due to the dynamic communication flows between data producers and consumers, the overlay topology of such systems can become inefficient over time and therefore requires adaptation to the existing load. Existing studies propose algorithms to design overlay topologies...
Multicast can jointly utilize the network resources when delivering the same content to a set of destinations; hence, it can effectively reduce the consumption of network resources more than individual unicast. The source of a multicast, however, does not need to be in a specific location as long as certain constraints are satisfied. This means the multicast can have uncertain sources, which could...
In a high-speed backbone network, the failure of a network link may cause large data losses, so it is necessary to reserve spare network resources for faster recovery. The conventional protection methods to reserve backup routes do not consider the failure probability of each network link, so the same amount of network resources for the backup route are needed regardless of the failure probability...
Geographic routing protocols establish scalable and robust routes for multi-hop trsdansmission in wireless mobile ad-hoc networks, where accurate location information of the mobile nodes is needed. Aiming to alleviate the influence of location errors, existing works focus on modifying routing protocols through modeling the error sources and mobility prediction. In this paper, we propose a cooperative...
Industrial wireless mesh networks technologies as WirelessHART, ISA100.11a, WIA-PA, e.g., have become a communication infrastructure for process control in harsh and noisy environment. These control systems are wireless mesh networked control systems (WMNCSs). Compared with wireless sensor networks, the Wireless network control systems have more stringent requirements on reliability and real-time...
Industrial automation has emerged as an important application of wireless sensor-actuator networks (WSANs). To meet stringent reliability requirements of industrial applications, industrial standards such as WirelessHART adopt Time Slotted Channel Hopping (TSCH) as its MAC protocol. Since every link hops through all the channels used in TSCH, a straightforward policy to ensure reliability is to retain...
This paper concerns the smart exploitation of multimodal communication capabilities of underwater nodes to enable reliable and swift underwater networking. To contrast adverse and highly varying channel conditions we define a smart framework enabling nodes to acquire knowledge on the quality of the communication to neighboring nodes over time. Following a model-based reinforcement learning approach,...
To achieve high reliability in on-chip networks, frequent runs of Built-in Self-Test allow the detection of and recovery from faults before they affect packets and the system functionality. However, to test routers, wrappers isolate cores from the network which leads to execution blocking and performance loss. In this paper, we propose a design-for-test reconfigurable router with two alternative bypassing...
A low-latency and reliable message switching network is critical for constructing high-speed datacenter networks. In this paper, we present the design, implementation, and evaluation of a novel Location basEd Source Switching (LESS) for datacenter networks. LESS enables lightweight source switching through a location-based addressing scheme. Each switch and host can independently derive a source route...
Maintaining the reliability of Next Hop selection (NHS) in Inter-Vehicle Communication (IVC) technology has witnessed significant attention among researchers nowadays. The reason is because reliable selection of the next hop could improve the performance of geographic routing protocols, which is a major goal of Intelligent Transportation Systems (ITS) applications. This paper provides a qualitative...

In WBAN miniaturized device nodes are planted within the blood stream or on the flesh. These device nodes are battery dependent, once the battery dies, node additionally...
Many vehicular ad hoc applications rely on vehicular broadcasting-based multi-hop routing to disseminate messages. In this work, we study the question of vehicular broadcasting-based routing. In particular, by modelling the vehicular message dissemination with a limited-time epidemic dynamics, we propose an online self-adaptive beaconing method to dynamically learn the optimal beaconing policy for...
The exponential growth of internet traffic over the last twenty years presents a real challenge to ISP looking to ensure a reliable and efficient service to their customers. Network traffic is far from being straightforward to predict and a deep understanding of the routing domains is a first requirement to achieve proper management of the traffic. This paper focuses on the monitoring and characterisation...

A novel HD-FO package platform was introduced with a hybrid RDL structure. An HD-FO package with hybrid RDL could enables higher routing density and multi die construction in a planner configuration. The 1-µm and submicron RDL wafers were fabricated at a foundry and then the essential parts of the inorganic RDL were integrated with Amkor's internal organic RDL process making a hybrid structure. Also,...
To deal with the uncertainty of container multi-modal transport, a container multi-modal transport route optimization model based on the reliability is proposed.
