Applying Multiple Deep Learning Models for Antipersonal Landmines Recognition

Antipersonnel landmines represent a very serious hazard endangering the lives of many people living in armed conflict counties. The huge number of human lives lost due to this phenomenon has been a strong motivation for this research. Deep Learning (DL) is considered a very useful tool in object detection, image classification, face recognition and other computer vision activities. This paper focuses on DL for the problem of landmines recognition in order to identify its type based on shape features. This research work consists of several stages: gathering a new dataset of Anti-Personnel Mines (APMs) images for training and testing purposes, employing several augmentation strategies to boost the diversity of training data, applying four different Convolutional Neural Network (CNN) models namely VGG, ResNet, MiniGoogleNet and MobileNet, and evaluating their performances on APMs recognition. In conclusion, results indicate that MiniGoogleNet exceed all of other three models in recognizing APMs with the highest accuracy rate of 97%.

A Comparative Study of VoIP over IEEE 802.11(b, g) and WiMax (UGS, ertPS) Wireless Network Technologies

This paper describes a comparative study of the performance of VoIP over wireless networks using OPNET tool. The simulation study is completed by running VoIP application in different network scenarios with IEEE 802.16 (UGS, ertPS) and IEEE 802.11 (b, g) with best effort service and interactive service The result clearly illustrated that the WiMax type ertPS has the best performance among all tested cases

Evaluating the Impact of Routing on QoS of VoIP over MANET Wireless Networks

In this paper, a performance analysis study for VoIP over mobile wireless ad hoc networks (MANET) is carried out using OPNET tool. The AODV, DSR, TORA, OLSR, and GRP routing protocols have been used as candidates to evaluate the impact of routing on quality of service (QoS) of VoIP application over MANET networks. Three different queuing mechanisms (FIFO, PQ, and WFQ) have been used also as nominee of queuing techniques. The VoIP is applied and the QoS is measured in terms of jitter delay, end-to-end packet delay, and wireless LAN media access delay and wireless throughput of 802.11 g technology with 54 Mbps

Performance Comparison of VoIP over MPLS-Based Networks with RSVP Protocol Using SIP, H.323 Signaling Protocols

This paper describes the usage of OPNET simulation tool to evaluate VoIP over MPLS networks which employs RSVP protocol as QoS mechanism with SIP or H.323 as signaling protocols for setting up VoIP calls over the Internet. The results showed that the H.323 with RSVP over MPLS networks produced minimal end-to-end delay than SIP protocol; making it a good choice as a signaling protocol with VoIP over MPLS networks for places requiring minimal end-to-end delay, while SIP reported lowest delay jitter with minimal call setup time

Applying MPLS Technique as On-Chip Communication Means for Network-on-Chip with Mesh Topology

This paper describes designing an efficient mesh topology Network-on-Chip system by employing MPLS protocol as an on-chip communication technique. A discrete-event simulator is developed in C++ to show the applicability of MPLS in providing efficient on-chip communication for multicore processing system-on-chip designs. Experimental results are compared with two simulators: wormhole equipped with virtual channels; and MPLS-based fat tree network-on-chip systems. Outstandingly, MPLS as on-chip communication means recorded better results than the wormhole +virtual channels in terms of throughput and packet end-to-end delay (latency).

Applying Genetic Algorithm to Solve Partitioning and Mapping Problem for Mesh Network-on-Chip Systems

This paper presents a genetic based approach to the partitioning and mapping of multicore SoC cores over a NoC system that uses mesh topology. The proposed algorithm performs the partitioning and mapping by reducing communication cost and minimizing power consumption by placing those intercommunicated cores as close as possible together. A program developed in C++ in which the provided specification of the multicore MPSoC system captures all data dependencies before any start of the design process. Experimental results of several multimedia benchmarks demonstrates that the genetic-based approach able to find different satisfied implementations to the problem of partitioning and mapping of MPSoC cores over mesh-based NoC system that satisfies design goals

A Simulation based analysis study for DDoS attacks on Computer Networks

A denial of service attacks are usually employed to interrupt the system's activity by getting a large number of fake requests, which leads to slowing down and stopping information system or network operations. This paper outlines the basic principles of DDoS attacks, explains how DDoS attack works. The paper presents an experimental using OPNET simulation tool in which traffic from three different applications VoIP, FTP, and HTTP is used to make the practical model with a firewall shield to model and simulate DDoS over Internet. However, three scenarios have been developed to illustrate different aspects of the DDoS over networks. The results clearly demonstrate how firewalls can be configured to mitigate DDoS attacks

QoS of Communication Networks Using MPLS protocol

This book chapter describes the place of MPLS in current state-of-the-art computer networking systems which emphasis the use of MPLS as a quality of service technique in different networking environments such as data centers and multimedia networking as a backbone networks. The chapter also includes practical experiments; which applied using OPNET network simulation tool; about transmitting multimedia over IP/MPLS networks and a fat tree data center architecture that employing MPLS. The examples show the feasibility of MPLS as a quality of service tool compared to best-effort IP networks. In addition, this chapter describes an effort of designing a network-on-chip system engaging MPLS mechanism as on-chip communication method which has been completely developed in C++. However, all results clearly confirm that MPLS is an efficient quality of service tool.
