Performance evaluation of ADV DSR & GOD in VANET for city & highway scenario
VANET has grasp the attention of various researchers in this field due to its wide range of applications in different fields i.e comfort, safety and entertainment. It is very expensive to test every networkprotocol or any network algorithm in real network by connecting a number of routers, computers and data links. Thus, in this paper QOS parameters like throughput, packet […]
Analysis of the Scalability and Stability of an ACO Based Routing Protocol for Wireless Sensor Networks
Wireless Sensor Networks (WSNs) are often deployed in remote and hostile areas and because of their limited power and vulnerability, the sensors may stop functioning after sometime leading to the appearance of holes in a network. A hole created by the non-functioning sensors in turn severs the connection between one side and the other side of the network and alternative […]
A cross validation of network system models for delay tolerant networks
This paper presents a cross validation of network system models in two simulation tools, namely the ONE Simulator and Scenargie, for the simulation of Delay or Disruption Tolerant Networks (DTNs). The study compares the simulation results from three network system models provided by the twosimulators as well as their efficiency for a commonly used DTN scenario. The results show a fundamental problem inherent to […]
A calibration based thermal modeling technique for complex multicore systems
A calibration based method to construct fast and accurate thermal models of the state-of-the-art multicore systems is presented. Such models are usually required during Design Space Exploration (DSE) exercises to evaluate various task-to-core mapping, associated scheduling and processor speed-scaling options for their overall impact on the system temperature. Current approaches require modeling the thermal characteristics […]
A new RA-DA hybrid MAC approach for DVB-RCS2
This paper proposes a new MAC scheme for DVB-RCS2 aimed to efficiently address M2M/SCADA traffic. The proposed scheme relies on the idea to complement Random Access (RA) schemes with Dedicated Access (DA) schemes, when traffic spikes feed the network. The rationale is to control the offered load on the RA slots pool to keep the packet […]
Real-Time Low Voltage Network Monitoring—ICT Architecture and Field Test Experience
Traditionally, distribution network monitoring has been focused on primary substations (i.e., high voltage/medium voltage level), whereas low voltage (LV) network has not been monitored at all. With rapid growth and penetration of distributed energy resources in LV grids, there is growing interest in extending the real-time monitoring to LV level. The framework program FP7 European Project INTEGRIS proposes an […]
A LiFePO4 battery discharge simulator for EV applications — Part 2: Developing the battery simulator
This paper, the second of the series on developing a LiFePO4 (LFP) battery discharge simulator for EV applications, presents an approach for developing the battery simulator. After the optimal battery model was established, in the first paper, the main drawbacks of battery simulator are addressed and a new strategy is proposed. This strategy uses neural networks (NN) for online estimation of the battery […]
Ctherm: An Integrated Framework for Thermal-Functional Co-simulation of Systems-on-Chip
This paper presents therm, an integrated framework for cycle-accurate thermal and functional evaluation of systems-on-chip. The presented framework enables accurate characterization of thermal behaviour by generating detailed physical models for components based on input specifications, and simulating them within a tightly integrated co-simulation platform with an embedded thermal simulator. Therm’s fine-grained modelling approach yields 70% higher […]
Cost Estimation of Parallel Constrained Producer-Consumer Algorithms
Cost estimation is crucial in the performance modeling of parallel algorithms and allocation of computational resources on distributed systems. This paper presents a novel methodology for estimating the cost of constrained producer-consumer (CPC) algorithms. In CPC algorithms, the computation is performed by classes of nodes (tasks), separated in time. The methodology combines data flow analysis […]
A raptor enabled data carousel for enhanced file delivery and QoS in 802.11 multicast networks
802.11 WLANs do not provide any standardized solution for reliable data multicast. Multicast packets are delivered to multiple clients as a simple broadcast service without support for Automatic Repeat Request. Hence, a fixed low speed (robust) transmission mode is generally used to improve the reliability of multicast files. However, this results in the inefficient use […]
