COMPARISON OF VOIP ON IPV4 ONLY NETWORK AND IPV6 ONLY NETWORK

Muhammad Fawad
The world is moving from IPV4 and going straight to IPV6 because of certain shortcoming in IPV4 such as address space exhaustion, large routing table, security problems, mobility and the quality of service that it ensured. In the coming era every-thing should be a network demanding a huge address space. IPV6 is thought to be the most important protocol for networks because of its availability features and handling the limitation of IPV4 in a better way. The aim of this research is to examine the...

A Study of Realized, Declared and Future EU-Accession Dates Using System Dynamics Modeling: The Case of Spain, Poland, Croatia and Turkey

M. Atilla ?ner, ?zgür Zan
In this study we propose an EU-Accession model that simulates the EU accession dates for the realized (Spain, Poland), declared (Croatia) and future (Turkey) accessions. The processualist approach is adopted and a System Dynamics model based on the EU’s standards is developed from a technical and institutional perspective. The model consists of three balancing loops: political stability, economic stability and adopting the acquis. These negative feedback loops exhibit a goal-seeking behavior tow...

Immune system and zinc are associated with recurrent aphthous stomatitis. An assessment using a network-based approach

César Rivera
Objective: The aim of this research was to identify genes, proteins and processes from the biomedical information published on recurrent aphthous stomatitis (RAS) using network-based foci. Methods: The clinical context was defined using MeSH terms for RAS and biomarkers, combined with words associated with risk. A set of protein coding genes was prioritized using the Génie web server and classified with PANTHER. For defining biologically relevant proteins, protein-protein interaction networks w...

Evaluation of channel estimation combined with ICI self-cancellation scheme in doubly selective fading channel

Lien Pham Hong, Quang Nguyen Duc, Dung Mac Duc
Orthogonal Frequency Division Multiplexing (OFDM) is a modulation scheme, which is used in several wireless systems for transferring data at high rate. The multi path fading channel and the frequency offset between the transmitted and received carrier frequencies introduce ICI (Inter Carrier Interference). ICI effects the OFDM symbols and degrades the system performance. This paper proposes a solution: combine channel estimation and ICI self-cancellation to combat against ICI in doubly selectiv...

Performance Evaluation of Routing Protocol on AODV and DSR under Wormhole Attack

Mojtaba GhanaatPisheh Sanaei, Ismail Fauzi Isnin, Majid Bakhtiari
Today’s Mobile Ad hoc Networks (MANETs) became a popular issue for scientists, and diverse studies have been made to increase the performance of ad hoc networks. In MANET nodes compromise to forward packets for each other communicate beyond their transmission range. The mobile nodes communicate with each other without any infrastructure. As wireless ad-hoc networks lack an infrastructure, they are exposed to a lot of attacks. One of these attacks called Wormhole Attack that two adversary node co...
