Modeling Campus VLAN using OPNET Simulation
Abstract: Virtual LANs have long been used within campus networks to create logical workgroups, independent of physical location or LAN topology. It is important to analyze VLAN capabilities, found in both wired and wireless devices, to tag and compartmentalize Wi-Fi traffic, supporting institution’s security and traffic management policies. A campus VLAN is modeled using OPNET modeler and traffic over VLAN is analyzed. Differences in throughput and network delay are compared over …

Impact of Ping Flood Attack and its Mitigation Technique: A Performance Evaluation
Abstract: Security has become the need of the hour as no organization is immune to data breach. A recent survey reports that 16% of attack on network is due to denial of service attack, which prevents legitimate users from accessing services or information. This paper focuses on ping flood attack, ping of death, SYN flooding and defense mechanism to defend the nodes being attacked in real time. Ping flood attack is …

Performance Analysis of AODV, OLSR and GRP Routing Protocols in MANET
Abstract: AbstractThis paper aims to compare performance of three routing protocols for Mobile Ad-Hoc networks (MANET’s). A Mobile Ad-Hoc Network (MANET) is a collection of wireless mobile nodes forming a temporary network without using any centralized access point, infrastructure, or centralized administration. In present study, a comparison of reactive routing protocol i.e., Ad Hoc On-Demand Distance Vector Routing (AODV), proactive routing protocol i.e., Optimized Link State Routing (OLSR) and hybrid routing …

A Survey of Wireless Network Simulators
Abstract: Wireless network simulators have become a basic need to study, evaluate and improve wireless networks. Wireless network simulators are very useful tool for a researcher to develop, test and diagnose wireless network protocols. Wireless simulations raise many new questions about appropriate levels of detail in simulation models for radio propagation and energy consumption and time taking for wireless networks. There are many different network simulators available in the world now, …

Improvising on Demand Protocol to Improved Energy Utilization in Wireless Sensor Network
Abstract: AbstractIn the 21st century, the advancement in technology is the wireless networks. In wireless networks, intelligent sensors are deployed in a physical area called as WSN (Wireless Sensor Network). All the sensor nodes are attached to a network and batteries are needed to provide energy to the nodes. Batteries may be in charged or discharged mode. During communication of all the sensor nodes, lot of energy is consumed. The main …

Simulation Based Performance Analysis of Wired Computer Networks
Abstract: Abstract Simulation is the process of accessing the real-world scenario in a virtual way. The purpose of simulation modeling is to ease the understanding of real working situations, to surge its behavior and its reactions during particular events. It is the application of computational models to the study and prediction of physical events or the behavior of engineered systems. Selection of a particular network simulator involves factors like availability of …
