This work presents a performance evaluation study of LOADng routing protocol in Internet of Things (IoT) applications. LOADng is a simplified light version of AODV developed taking into account the limited resources of IoT devices. Initially created in 2011, LOADng emerges as an alternative to the standard RPL protocol. The use of LOADng is justified once several studies has exposed the drawbacks...
Understanding per-packet routing dynamics in deployed and complex wireless sensor networks (WSNs) has become increasingly important for many essential tasks such as network performance analysis, operation optimization, system maintenance, and network diagnosis. In this paper, we study routing path recovery for data collection in multi-hop WSNs at the sink using a very small and fixed path measurement...
DSR protocol is less considered for practical application due to its more limitations against other routing protocols. Modification in DSR protocol can make it considerable and it can improve energy efficiency to enhance lifetime of battery operated mobile adhoc networks. This paper proposes the modification for route discovery mechanism in normal DSR protocol for energy efficient route establishment...
Early design space exploration has been shown to be an important factor in reducing the development time for Network on Chips. In this paper, we present a Matlab toolbox aimed at the early-stage design space exploration for NoC router design, the router founding element of a NoC. The toolbox is based on the discrete event simulation engine SimEvents. The presented toolbox can be used to graphically...
Energy optimization has become a crucial issue in the realm of ICT. This paper addresses the problem of energy consumption in a Metro Ethernet network. Ethernet technology deployments have been increasing tremendously because of their simplicity and low cost. However, much research remains to be conducted to address energy efficiency in Ethernet networks. In this paper, we propose a novel Energy Aware...
Wireless Sensor Networks (WSNs) have emerged recently as one of the most attractive research subjects. The resource-constraint characteristics of WSNs limit the secure design and development of security protocols and presumably thwart the integration of an intrusion detection system (IDS). Whilst, sensor nodes which usually operate in unattended and even harsh environments, are prone to failures and...
ZigBee devices are resource-constrained. So, they cannot run traditional heavyweight routing algorithms. Although, ZigBee proposed a table-free, simple routing algorithm for tree networks, it does not support long linear networks typically set up in roadside, mines, agricultural field, mountains etc In this paper, we have proposed a light-weight routing algorithm based on source routing that supports...
We investigate the problem of managing the lifetime of links in IP backbone networks exploiting a sleep mode (SM) state. In particular, the SM duration tends to increase the lifetime, while the frequency of power state transitions tends to decrease it. After optimally formulating the problem of limiting the impact on the link lifetime when SMs are applied, we propose an online heuristic, called AFA,...
Content-centric networking (CCN) is being considered as a paradigm for the Future Internet. CCN is focused on the content itself rather than the host. CCN can be used to enhance the performance of delivery latency, robustness, and security. One of the immediate needs that CCN has to address is mobility support because the number of users who are using mobile devices is increasing rapidly. Users demand...
With the spread of mobile devices and development of the network, the user can use the data anytime anywhere. Especially, most users have become more sensitive to the quality of communication for the use of real-time video services. In this paper, we propose the SDN-based device-assisted network that improves network environment by device's feedback on the status of the network. When low network performance...
Wireless cellular network has recently emerged as one of the popular technologies for the next generation network due to the development of smart phone technologies which resulted in high mobility of user and achieving Quality of Service (QoS) for application like video conferencing, video streaming etc… requires an efficient multicast routing protocol which is one of the most key performance metrics...
Wireless Sensor Networks (WSN) consists of many small compact devices equipped with sensors. It is a very popular area for exploration. The nodes are movable and set themselves into a network. However in larger networks, geographical routing protocol is required. Geographical routing uses location information to send the packets to the target region. In this paper, some of major geographic routing...
In vehicular sensor networks (VSNs), an increase in the density of the vehicles on road and route jamming in the network causes delay in receiving the emergency alerts, which results in overall system performance degradation. In order to address this issue in VSNs deployed in dense urban regions, in this paper, we propose collaborative learning automata-based routing algorithm for sending information...
Distributed clouds have been regarded as the key enabling technology to provide new trends of services. The contribution of this paper is twofold. First, we discuss current distributed clouds architecture and highlight the issues involved, specifically scalability. Second, we investigate the benefits of the use of the Recursive InterNetwork Architecture (RINA) as a networking solution for the distributed...
Routing in SDN-enabled networks with middle-boxes enables high level of control over network flows so that desired level of security, efficiency and performance can be achieved. However, the new capabilities place constraints on available resources such as switch memory and middle-box processing capacity. Additionally, flow traversal constraints may also arise where each network flow has to visit...
In this paper, we present preliminary results from a performance comparison between the two multicast routing protocols ODMRP and SMF. While SMF uses a proactive selection of forwarding nodes, ODMRP is a reactive approach to multicast routing. For the evaluation, we use an two-step approach. First, we perform emulation-based measurements in a virtualized test bed utilizing the ns-3 IEEE 802.11 model...
In the future, mobile ad hoc network (MANET) is predicted to play more important roles for device communication with self organized infrastructure. Effectiveness of routing protocols and congestion control mechanisms, highly determines the performance of MANET. Previous research in protocol development did not pay much attention in selecting the appropriate protocol on other layers. Therefore, the...
Pervasive networks formed by users’ mobile devices have the potential to exploit a rich set of distributed service components that can be composed to provide each user with a multitude of application level services. However, in many challenging scenarios, opportunistic networking techniques are required to enable communication as devices suffer from intermittent connectivity, disconnections and partitions...
Due to network dynamics, performance tuning is often indispensable in network management. In this paper, we propose MOE, a framework integrating network performance monitoring, optimization and evaluation. This is a trial towards the top-down and systematic management of network performance. We validate MOE based on a typical scenario in the real network environment. Results show that MOE can collect...
