The field of wireless sensor networks is progressing at a very rapid pace with one of its major application in the area of agriculture. Several research problems have been addressed and solutions have been proposed. Most of these works are based on single crop scenario. Research done in the multiple-cropping scenario, where two or more crops are sown in a single field in the same year, are very few...
The efficiency of inter-domain routing in large-scale mobile network environments is a critical issue, as traditional prefixed addresses may fail due to the dynamic topologies of mobile networks, where devices would be required to maintain massive routing tables. To address this issue, in this paper we leverage the principles of probabilistic data structures in the inter-domain routing scheme, and...
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...
Border Gateway Protocol (BGP) has been and will still be the de-facto standard for inter-domain routing in the Internet. However, the problem of routing oscillations in BGP has not been well addressed, which can introduce lots of unnecessary routing updates and severely degrade network performance. In particular, existing studies need a great effort to be deployed or introduce a large overhead. In...
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 internet of vehicles (IOV), on-board Ad hoc network between vehicles is established randomly and freely based on dedicated short range communication technology, enabling the vehicles beyond visual range of drivers and signal transmission range of on-board communication equipment to establish communication connection for transmission and sharing of information and data through single-hop and multi-hop...
Information-Centric Networking (ICN) proposals rethink the communication model around named data, in contrast with the host-centric transport view of TCP/IP. The content retrieval in ICN is natively receiver-driven, chunk-level based, multi-path forwarding and intrinsically coupled with in-network caching. To make the best use of in-network caching resources, NDN router should acquire the view of...
Although the importance of Disaster Response Networks (DRNs) has been highlighted in many researches, the requirement of spectrum agility has not been well addressed. In this paper, we focus on using all-spectrum cognitive radio for DRNs to fulfill this requirement. We consider a DRN constructed by Cognitive Radio Base Stations (CRBSs), which are deployed in the disaster affected area. Each CRBS is...
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...
The Internet is often thought to be a model of resilience, due to a decentralised, organically-grown architecture. This paper puts this perception into perspective through the results of a security analysis of the Border Gateway Protocol (BGP) routing infrastructure. BGP is a fundamental Internet protocol and its intrinsic fragilities have been highlighted extensively in the literature. A seldom studied...
Internet plays an increasingly significant role in our modern life style for our society, educational institution, engineering systems and industrial applications. It serves billions of users worldwide every day by carrying an extensive range of traffic from sources to desired destinations. Along with these advances, inter-domain routing nodes of internet are facing challenging issues like scalability...
Thanks to their flexibility and their simplicity of installation, Wireless Mesh Networks (WMNs) allow a low cost deployment of network infrastructure. They can be used to extend wired networks coverage allowing connectivity anytime and anywhere. However, WMNs may suffer from drastic performance degradation (e.g., increased packet loss ratio and delay) because of interferences and congestion. Generally,...
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...
In the common implementation of software defined networking where only one controller is used, tasks required by various applications may overwhelm the controller as the network grows, leading to degradation of the network performance. Some multi-controller architectures have been proposed to remedy such scalability issue. In this paper, we present our design and implementation of a routing application...
In this paper, a low power wireless mesh network over channel hopped TDMA links is introduced as an area network for connecting things. The links and virtual links over the IEEE 802.15.4e DSME MAC are established and unbalanced cluster-tree based network formation provides routed link paths for the things to have deterministic-latency and scalable wireless mesh connectivity.
Mesh-Tree architecture is an enhanced architecture in NoC. In a three dimensional Mesh-tree topology every layer may be treated as mesh and trees are used to connect adjacent layers. This type of architecture is very efficient for broadcasting as well as high speed communication. Chip multiprocessors are becoming more widely utilized to efficiently use the increasing number of transistors available...
We address the problem of RPL tree formation in self-organized, multi-hop, wireless sensor networks, where resource-constrained nodes may independently select their routing paths that maximize their performance. We study the result of the tree formation applying a non-cooperative gametheoretic model, and show that multiple objectives may lead to unstable Nash graphs with unwanted traffic cycling....
In developing countries, disaster areas, and other places where communication infrastructure is unstable, people need a system that allows them to easily install a network in any location. In this paper, we propose the mesh network named Adaptive Multi-Gateway Mesh Network (AMGMN). AMGMN supports wired and wireless LANs. The combination of wired and wireless LANs prevents radio interference and ensures...
