Routing algorithms can improve network performance by maximizing routing adaptiveness but can be problematic in the presence of endpoint congestion. Tree-saturation is a well-known behavior caused by endpoint congestion. Adaptive routing can, however, spread the congestion and result in thick branches of the congestion tree — creating Head-of-Line (HoL) blocking and degrading performance. In this...
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...
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...
With the development of wireless transmission technology, the coexistence of a variety of network protocols is inevitable in industrial control networks for a certain period of time. Due to the lack of a necessary coordination mechanism between different network protocols, this may impact the transmission performance of the backhaul network connecting several subnetworks with different protocols when...

Hierarchical routing resources play vital role in FPGA routing. Better routability options can be obtained using segmented approach of wires thus enabling routing optimization. Source and sink logic blocks can be connected via wire segments such that the overall wire length and switching transistors inside the switch box can be saved over an extent. This paper presents an experimental approach of...
There are some shortcomings in the delay tolerant network (DTN) routing algorithm, such as low message delivery rate, low network efficiency and high cost in the satellite network. In order to solve the problem above, this paper proposes a limited copy algorithm MPWLC based on service probability. In MPWLC, not only is the number of copies limited, but the storage resources of the satellite are also...
In this paper, we firstly propose the concept of aerostat cluster in the space and ground integration network. Then we discuss the structure of the near space aerostat network based on the business requirements of communication. After that, we design the routing algorithm (named ISPR) in near space network and make an in-depth analysis. Lastly, we propose an access method (named G_AAT) to achieve...
As the scale of parallel computer systems becomes larger year by year, interconnection networks with low node degree and short diameter are required for achieving high communication performance at low cost. This paper presents a general alternative to hypercubes, named KMS-Cube, that keeps interesting topological properties of the hypercube but has a low node degree. A KMS-Cube, denoted by KMSC(k,...
A radial increment WSN routing algorithm(RIRA) is proposed to reduce energy consumption and improve transmission efficiency caused by complex environment and narrow tunnel of deep mine, in which the wired network layout is limited. Multi-hop routing methods between clusters can reduce energy consumption. A weighting formula is constructed to select cluster heads, the greater the weight, the more likely...
Wireless Mesh Networks (WMNs) employ hybrid distributed mobile networks with instant deployment and capabilities Such as: self_healing, self_organization and self_configuration. These abilities make WMNs a likely technology for incident communication. An Incident Area Network (IAN) requires a reliable and efficient routing path in an environment, where infrastructure-based communications have been...
Mobile social network (MSN) is a type of delay tolerant network explicitly considering social characteristics of the terminal nodes. The existing Ad Hoc routing protocols assume that there is at least one complete communication path between the source node and the target node. So they cannot be applied to MSN directly. The key to solve the problem of content distribution in mobile social network is...
This paper proposes a decision model based on fuzzy logics to assign the route between source-destination nodes in elastic optical networks. The route is chosen dynamically based on the lowest cost criterion, which is calculated based on a weighted summation of three metrics, called availability of contiguous slots on the route, average availability of slots on the route and physical length of the...
Routing algorithms play an important role in Network-on-Chip (NoC) based System-on-Chips. Turn model based routing disallows some of the turns in order to avoid deadlock, while providing partial adaptivity. In this paper, all 2D uniform turn models are examined for deadlock freeness and connectivity; 50 deadlock free turn models are extracted that provide full connectivity in the network. An extended...
The locally twisted cube provides a prospective topology suitable for interconnection networks of the massively parallel systems. A routing algorithm is proposed in this paper that tolerates faulty vertices in locally twisted cubes based on two kinds of routing probabilities. A computer experiment is also conducted to verify the performance of our algorithm.
As the development of processors/SoCs (System-on-Chips), NoC (Network-on-Chip) consumes an increasing fraction of the modern processors/SoCs power. Thus, designing energy-efficient NoC architecture is imperative. Multi-NoC (Multiple Network-on-Chip) behaves well in power gating for reducing leakage power, which constitutes a significant fraction of NoC power. In this paper, we propose CRA, a novel...
