Freedom from deadlock is one of the most important issues when designing routing algorithms in on-chip/off-chip networks. Many works have been developed upon Dally's theory proving that a network is deadlock-free if there is no cyclic dependency on the channel dependency graph. However, finding such acyclic graph has been very challenging, which limits Dally's theory to networks with a low number...
As an efficient multi-core system structure, three-dimensional Network-on-Chips (3D NoC) opened a new filed of System-on-Chip (SoC) research. In this paper, we present an efficient routing algorithm for 3D NoC applications. This method is based on west-south-first routing algorithm and intra-layer routing has higher priority. We introduce the concept of possible deadlocked configurations and further...
Computer Network has great effect on improving the efficiency of the communication system and application requirements in our life. In order to establish transmission path with movement characteristics and improve the efficiency of information transmission in Computer Network, the optimized clustering routing protocol based on node position using the minimum distance routing competition mechanism...
This paper proposes an algorithm that uses predefined weights to create broadcast routes for a WirelessHART network. The network topology is represented by a graph, and the algorithm uses information of the devices present in the network to build the broadcast graph. At each iteration of the algorithm, a device is selected and then added to the broadcast solution graph. A cost function determines...
Power consumption is a key issue for wireless network design. Cooperative routing, an efficient scheme for saving transmission power in wireless networks, combines the advantage of the cooperative communication in the physical layer and the routing technology in the network layer. In this paper, we propose a distributed minimum power cooperative routing algorithm based on optimal power allocation,...
As the technology scales toward deeper submicron, system-on-chip designs have migrated from fairly simple single processor and memory designs to relatively complicated systems with higher communication requirements. Network-on-chip architectures emerged as promising solutions for future system-on-chip communication architecture designs. However, the switching and routing algorithm design of network-on-chip...
The quality of service multicast routing problem (QoSMRP) is a very interesting research issue for transmission in communication networks. It is known to be an NP-hard problem, so many heuristic algorithms have been employed for solving this problem. This paper proposes two hybrid approaches based on the hybridization of Firefly algorithm (FA) with Quantum Evolutionary algorithm (QEA) to solve the...
In this work, we model route updates as part of Quality of Service (QoS) Virtual Network Function (VNF) in Software-Defined Networking (SDN) architecture. In SDN, the control plane and the data plane are decoupled. This allows high flexibility by providing abstractions for network management applications and being directly programmable. However, reconfiguration and updates of a network are sometimes...
A lot of research has been proposed to improve network performance in the data center. However, with the development of distributed applications, these applications face a new performance bottleneck since existing solutions almost ignore the application level optimization. The concept of coflow has been proposed which provides a chance for us to optimize network in application level rather than individual...
Development of semiconductor process makes devices have smaller area, lower power, and reduced wire connections. To achieve this purpose, macro placement plays an important role in the design flow. In this paper, we present a routability-driven macro placement algorithm considering pins location to optimized scaled routing congestion and macro placement area. By considering pins location, reclassify...
Wireless Sensor Network (WSN) is widely used in IOT, military and environmental application. However, WSN is energy-constrained and the network nodes placed in hostile environment are hard to replace. Therefore, designing an energy-efficient routing algorithm is significant. Many solutions have been proposed to optimize energy consumption in conventional wireless sensor network, but they don't work...
Multilayer Clustered Designing Algorithm is exploited to present MCDA - Hot Spot algorithm; a technique to increase the network throughput by alleviating the impact of hotspot issue on network lifetime. The network nodes in the hot spot region are in a flat layer form in contrast to rest of the network nodes that are grouped into clusters. This design substantially helps in achieving goal above. This...

With the expansion of EVs' range as well as the development of fast charging technology and related infrastructure, large-scale EVs are involved in intercity transportation systems and power transmission systems. We propose a traffic-power integrated network model and...
As an emerging technology, software defined networking (SDN) allows flexible control of network devices and supports user applications with guaranteed quality of service (QoS). To achieve flow transmission between two non-adjacent switches in SDN, efficient routing algorithm should be designed. In this paper, we jointly consider route selection and flow allocation problem. To stress the service sensitivity...
In some special circumstances, e.g. tsunamis, floods, battlefields, earthquakes, etc., communication infrastructures are damaged or non-existent, as well as unmanned aerial vehicle (UAV) cluster. For the communication between people or UAVs, UAVs or mobile smart devices (MSDs) can be used to construct Mobile Ad Hoc Networks (MANETs), and Multipath TCP (MPTCP) can be used to simultaneously transmit...
Swarm of drones are increasingly deployed to perform a variety of critical missions such as surveillance, rescue in disaster areas etc. To guarantee success of a mission, the controlling software should pursue two goals. Firstly, it should ensure safety, i.e., guarantee collision avoidance. Secondly, it should prevent a premature depletion of the batteries of the drones by minimizing their travel...
Among the schemes proposed for failure recovery in software-defined networks, installing backup paths in advance is considered to be an effective approach to reduce the recovery latency. However, the pre-installation poses undue storage overheads on flow tables. In this paper, we propose a customized and cost-efficient backup scheme, which achieves fast recovery from any single-link failure. We introduce...

In Information-Centric Networks (ICN), contents are cached on some intermediary routers. This creates thus a new situation which is totally different from the traditional path-selection paradigm: the source/destination paradigm no longer exists; instead, the new paradigm is how to find a path through a selected group of caches, so that the content is delivered via the shortest way. This paper addresses...
