Abstract

Nowadays, the VPN (Virtual Private Network) technique is one of the most common and important implementations in IT and other companies. VPN technology is divided into two categories: (i) overlay VPN and (ii) peer-to-peer VPN. In overlay VPN, ATM and frame relay are included, and peer-to-peer VPN includes IP-routing. VPN technology is becoming more and more important because of its security, convenience of working with VPN, real-time application, and low construction cost. When compared to traditional VPN, MPLS VPN (Multiprotocol Label Switching) is a good solution for real-time. MPLS VPN is an advanced technology, and it has advanced features. MPLS VPN has functions like FEC, VRF, MPBGP, and VPNv4. These functions are used to overcome the disadvantages of traditional VPNs. The disadvantages of traditional VPNs are (i) complex management, (ii) lack of availability, (iii) complex implementation, (iv) expansibility, and (v) customer address overlapping. In this paper, the implementation of the MPLS layer 3 VPN technique is used to connect and share information between different branches of different customers which are geographically separated. Here, a private IP address instead of a public IP address is used to connect and share the information. The MPLS VPN technique is used to provide flexibility for the customer through their ISP (Internet Service Provider).

Abstract

This paper presents intersection collision avoidance in a vehicular ad hoc network. A vehicular ad hoc network (VANET) is a technology that uses moving vehicles as network nodes to create a mobile network. In VANET, every participating vehicle is a wireless router or node. When vehicles are intersected at a crossing, an accident situation will occur. To avoid this situation, the congestion control concept is presented in this paper. This paper reviews various existing MAC protocols used for congestion avoidance. In this paper, IEEE 802.11 protocols are used for congestion avoidance of vehicles.

Abstract

Antennas have evolved rapidly since the advent of the wireless network. With the emergence of many new wireless standards in each generation of wireless networks, multi-band antennas have been developed to combine many standards into one device. In this paper, the authors have designed and studied a four-band patch antenna by CPW feeding for modern wireless communication systems, GPS navigation, Wi-Fi, and satellite communication applications. Simulation results of the antenna show that the antenna radiates at four frequency bands, such as 1.8356 GHz for the GPS standard, 2.9765 GHz, 3.7902 GHz, and 5.3977 GHz frequency bands for WLAN standards IEEE 802.11a and IEEE 802.11b & g, and 3GHz–3.63GHz for the WiMAX standard. The proposed antenna results are carried out by the CST software. The antenna characteristics such as return loss, VSWR, radiation pattern, and 3D polar plots are analyzed.

Abstract

Intelligent analysis is used to process the structure of a wireless sensor network (WSN) and produce some information that can be used to improve the performance of the WSN's management applications. This paper introduces a new approach for wireless sensor networks which is based on neural networks. The presented work is an intelligent method based on the existing concept of multi-agent systems for WSN management. The proposed work shows a performance improvement. Wireless sensor networks need to be managed in different ways, e.g. power consumption of each sensor, efficient data routing without redundancy, control of data reading and sending intervals, etc. The random distribution of wireless sensors, the numerous variables that affect the operation of the WSN, and the uncertainty of various algorithms (for example, self-localization of sensors) make the WSN fuzzy. Given this fuzzy nature and numerous details, a neural network is an ideal tool to use to cover these details, which are so difficult to detect and explicitly, model. This paper presents a neural network-based approach, which results in more efficient routing path discovery and sensor power management.
