Regarding optimized logic network generation, recent papers have demonstrated that non-series-parallel topologies can deliver arrangements with fewer transistors when compared to the widely used series-parallel approach. However, due to its topology particularities, this paradigm represents a challenge for physical cell design, especially concerning the transistor placement procedure. In this scenario,...
Resiliency, the capability to detect and react after a node failure in the network, is a key element for any network protocol. First, the detection of the failure must be quick to prevent dropping the packets and degrading the throughput too badly. Then, the repair, the computation of another path, has to allow the traffic to reach the destination without too much delay and without increasing the...
This paper focuses on the design of self-organizing algorithms for mesh topology formation between low-power short-range heterogeneous devices. To this end, we consider randomly deployed devices that are heterogeneous in terms of characteristics such as energy source (e.g. mains, rechargeable battery, and coin-cell), computational resources, and communication capabilities. Resilient topology formation...
Threat propagation analysis is a valuable tool in improving the cyber resilience of enterprise networks. As these networks are interconnected and threats can propagate not only within but also across networks, a holistic view of the entire network can reveal threat propagation trajectories unobservable from within a single enterprise. However, companies are reluctant to share internal vulnerability...
The performance of wireless mesh networks (WMNs) deployed for Internet access in rural settings is affected by several factors. Typically, deployments in African domains use cheap and computationally constrained devices with challenges such as power fluctuations, gateway congestion, VSAT communications asymmetry and low bandwidth, which affects throughput under dynamic scenarios. Caching methods can...
In this paper, we study the disconnection of a moving vehicle from a linear access network composed by cheap WiFi Access Points in the context of the telecommuting in massive transportation systems. In concrete, we analyze the probability for a user to experience a disconnection longer than a threshold t∗, leading to a disruption of all on-going communications between the vehicle and the...
Sensors play a vital role in the growth of big data as they are being used in numerous data-intensive applications. This paper introduces a multilayer big data aggregation framework and a priority-based, dynamic data aggregation (PDDA) scheme. The proposed PDDA approach works at the bottom layer at sensors (i.e., data collecting node) as opposed to most existing approaches which only consider aggregating...
As the current decade is witnessing a shift from traditional System — On — Chip (SoC) to Network — On — Chip, but the inherent problems such as congestion, latency and delay still remains the major issues of concern. The effect of these issues in a chip may somehow be minimized by carefully designing a topology and a suitable routing algorithm which offers both path diversity and scalability. In this...
In building automation systems, the diversity of existing field level networks is a major challenge for fully integrated solutions. Typical approaches achieve integration by shifting the needed complexity to the automation or management layer. In contrast, this paper focuses on leaving the complexity at the field level to provide a homogeneous view to upper layers without compromising reliability...
The Advanced Metering Infrastructure (AMI) is a fundamental component of the Smart Grid architecture. The AMI consists of a collection of Neighborhood Area Networks (NANs), which interconnects the smart meters to the utility company. In this paper, we address two important performance metrics regarding the NAN design, the topology's resilience and the network capacity. We propose an analysis methodology...
We describe a novel wireless backhaul solution, called Self-Optimizing Wireless Mesh Network (SWMN), which is targeted for interconnecting 5G small cell nodes cost-efficiently and smartly. SWMN is not only highly resilient and scalable, but it is also equipped with advanced Self-Organizing Network (SON) capabilities offering autonomous network configuration and traffic engineering features. The key...
Recent works demonstrate constant optimizations in the number of transistors necessary to implement some logic functions by using non-series-parallel arrangements. However, these kind of networks can produce non-dual and non-planar structures, which cannot be fully treated by some of the classical algorithms dedicated to placement. In this paper we present two methodologies to place and route non-series-parallel...
There has been a rapid rise in the IP traffic throughout the Internet which takes advantage of the already established widespread IP infrastructure. Different suggestions are being explored to facilitate the next-generation access networks via IP mechanisms, with a growing trend towards a flat-IP structure and novel topological set-ups in the backhaul. Aligned with this evolution, there are increasingly...
Most African countries including Senegal face a deficit of doctors. This paper presents a new architecture at lower cost allowing the use of Access Point to pass the data from biosensors to the collects used in the field of medicine. The paper proposes a new QoS management prototype to put as priority traffic from biosensors at the expense of traffic from other types of clients in order to receive...
In this paper, we present Heterogeneous Network Clustering (HNC), a novel clustering algorithm for the establishment of distributed service registries in heterogeneous stationary wireless networks. HNC is deterministic and distinguishes between nodes that must, may, or must not become cluster heads and/or gateways — hence heterogeneous networks, such that constraints regarding functionality and energy...
MOS planar technology has been used in fabrication of integrated circuits in the last decades. However, the short channel effects in the subthreshold operation region are becoming a critical restriction to the channel length reduction. With the use of FinFET devices, the scaling increases due the reduction of short channel effects. FinFET offers the possibility of independent gate controlling that...
Visual management for industrial wireless sensor network not only requires quickly data process, but also the higher interact ability of graphical interface. However, the visual management has exists now which are just publish the equipment and relationship by list, they are little relate to simulated reality topological distribution. Based on research the topological structure of ISA100.11a protocol...
Point to multipoint multicast (MC) packets delivery without optimal distribution trees is prone to unnecessary retransmissions that adversely influences narrow-band VHF networks. The bandwidth efficient MC packet delivery path has to be calculated to best reach all destinations using the inherent broadcast nature of VHF radio subnets by avoiding retransmissions of the same message/packet in the same...
The paper presents a mathematical statement of the problem of finding a rational topology of wireless sensor networks (WSN) using unmanned aerial vehicles (UAVs), which consists of problem of sensor localization in monitoring zone and problem of UAV relays localization in the space for the organization of connected network with desired characteristics.
Nowadays, in-vehicle network design has become a difficult challenge due to increased complexity and strict real-time constraints. In this work, we propose an integrated framework for CAN network topology design under real-time constraints. The framework integrates topology design with real-time analysis. It firstly allocates electronic control units (ECU) automatically to one of the CAN buses via...
