Recent advances in technology propelled the development of resource constrained tiny devices and the concept of Internet of Things (IoT). Potential applications spanning various fields of science from environmental to medical have been emerged. Different architectures, routing protocols, performance issues and goals have been suggested. In this work, we review fundamental concepts, recent developments...
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...
In recent years, many routing protocols that take into account particular vehicular ad hoc network (VANET) characteristics such as higher vehicle speeds and mobility patterns have been proposed. Most of the existing VANET routing protocols largely neglect vehicles as obstacles in VANETs. Obstacle shadowing caused by large vehicles such as trucks or buses more negatively affects packet transmission...
Although IEEE 802.11p technology is standardized for road safety and efficiency applications, the channel congestion problem is its key weakness necessitating distributed congestion control (DCC) algorithms on different layers of the communication stack. In this paper, we propose DCC-enabled Contention based Forwarding scheme targeting multi-hop dissemination of Decentralised Event Notification Messages...
In this paper we analyze the applicability of onion routing on Predictable Delay-Tolerant Networks. We show that a simple approach for providing anonymity through the application of a simple onion routing can be feasible in some scenarios. To that end we evaluate our proposal on a network based on a city public bus transportation network.
BTLive is a novel, unique, mesh/push-based peer-to-peer (P2P) live video streaming mechanism. Previous studies show that it achieves significantly lower streaming delays than other approaches but suffers from a high overhead, where peers receive up to 33% duplicate video chunks. Other P2P streaming mechanisms, most of which are either mesh/pull or tree/push-based, do not experience duplicates at such...
The rise of Software Defined Networking (SDN) presents an opportunity to overcome the limitations of rigid and static traditional Internet architecture and provide services like network layer multicast for live video streaming. In this paper we propose mCast, an SDN-based architecture for live streaming, to reduce the utilization of network and system resources for both Internet Service Providers...
In this paper, we propose a new geographic holebypassing routing algorithm based on virtual convex model in Wireless Ad hoc Networks (WANETs). Our method is to convert an actual hole into a basic virtual convex first and then use line segments that are parallel to the basic virtual convex to find candidates of anchor points. Later, among these candidates, we choose appropriate anchor points to be...
This paper describes the development of a data exchange protocol for self-organizing computing environments with minimal latency. The protocol is implemented using standard software libraries for mobile device networks. The neighborhood method involves building a route using two broadcast requests, and the method proposed here is implemented using two broadcast requests. One of these requests is issued...
Energy is the most limiting factor for remote outdoor deployments of Wireless Sensor Networks (WSNs). This paper proposes a novel routing algorithm for dual-platform nodes targeting WSN applications as found in smart farming applications. For scenarios in which high power components of nodes and radio links will be switched on at known points in time, our algorithm tries to make use of scheduled uptimes...
Multi-level clustering offers the scalability that is essential to large-scale ad hoc and sensor networks in addition to supporting energy-efficient strategies for gathering data. The optimality of a multi-level network largely depends on two design variables: 1) The number of levels, and 2) The number of nodes operating at each level. We characterize these variables within a multi-hop, multi-level...
Delay-tolerant networks (DTN) are sparse mobile ad hoc networks where contemporaneous end-to-end path is typically not available. Therefore, nodes act as relays for each other to enable data delivery. The cooperation among mobile nodes however can be hindered by selfish users. Incentive schemes are inevitably introduced to regulate the behavior of DTN users. The motivation of this paper is to seek...
Software Defined Wireless Sensor Network (SDWSN) is realised by infusing Software Defined Network (SDN) model in Wireless Sensor Network (WSN), Reason for that is to overcome the challenges of WSN. Artificial Intelligence (AI) and machine learning play an important role in our society, give rise to systems that can manage themselves. WSNs have been used in various industrial applications, where reliability...
The penetration of electric vehicles (EVs) has attracted growing research interests in its impact on both power and traffic networks. 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...
Most learners are introduced to academic papers in their graduate work. Typically, most of us learn to read and understand these papers by reading many of them and listening to more senior colleagues and teachers describe and interpret these papers in the class or reading groups. As our experience grows we become better at this skill. There is a need to read papers in a particular research area to...
The Network on-Chip (NoC) is considered as an emerging technology for distributed embedded systems which is proposed as an alternative interconnection solution in Mutli-Processors System on-Chip (MPSoC). This paper proposes a graphical toll that allows researchers to generate and configure quickly their Network on-Chip in the hope to evaluate easily their contributions in no time. Unlike major existing...
Software Defined Networks split the data plane from the control plane. They can be used in wireless networks and will bring flexibility, less interference, simple management, less energy consumption and load balancing. They can also improve service quality, handover and mobility between different service providers. In previous methods, when link states were changed the controller deleted the stored...
We study the problem of seamlessly updating several routes in a network, in the context of Software-Defined Networking (SDN). A set of routes pairs (Ci, Ni) is given, where each new Ni should replace the existing Ci. We look for a way of gradual updating, so that routing cycles are never created during the replacement process. In that, we follow the recent paper of Delaet et al., which considered...
The occurrence of multiple holes in wireless sensor networks poses many challenges in designing routing protocols. The traditional scheme is forwarding packets along the hole perimeters. However, this scheme leads to two serious problems: data concentration around the hole boundaries and routing path enlargement Recently, several approaches have been proposed to address these two problems, wherein...
In this paper, we propose different techniques for message passing and event-driven communication among hierarchically organized objects. Proposed techniques are suitable for dynamic tree-structured applications, where application entities are organized in a tree and added to it in run time. Examples of such applications are modeling and simulation tools where application objects often follow parent-child...
