1. Abstract Although 4G network in some areas not yet fully universal, but the most recent 5G this topic has fired up. 5G network as a next generation mobile communication network, its theoretical maximum transfer speeds of up to tens of Gb per second, which is far more than the transmission rate of the existing 4G network, the whole ultra-high-definition movie can be downloaded completed within one second. 802.11ac technology are used in fifth generation network as a mainstay. It has also become

A wireless local area network (WLAN) is a wireless distribution method that uses high frequency radio waves to connect two or more gadgets. It allows users to communicate between network-enabled devices within and around the coverage area. More and more organizations are spending on WLAN because it has become a mission-critical component of the corporate network. One of the main benefit that WLAN offers is the convenience, it allows the home and corporate users to access network resources from anywhere

Introduction to 802.11 WLAN A WLAN is a network that helps to attach two or more devices using wireless techniques like spread spectrum. It access in limited area like schools, colleges, organizations, offices, and computers labs etc. This helps the clients to access even while roaming near about that area and still they remain connected with network. In the industries or complexes, wireless LANs helps the customers to access to the internet and they can access without any installation, giving

A Performance Analysis OF VoIP Traffic Over Wireless Lan And Wan Using Different Codecs Tasnim Abdalla Abbas Mohamed * Dr.Amin Babiker A/ Nabi Mustafa Department Of Communication Engineering .Al-Neelain University ABSTRACT A simulation model is presented to analyze and evaluate the performance of VoIP based integrated wireless LAN/WAN with taking into account various voice encoding schemes. The network model was simulated using OPNET Modeler software. Different parameters that indicate

The IEEE 802.11g standard This is a direct extension of the 802.11b that extends the maximum data rate to 54Mbps, making it possible to serve up to five times as many users. Our Wi-Fi network is based on the IEEE 802.11 b/g standards, which is the most commonly used standard. We have added Wi-Fi access points in our network to give easier access to corporate data and services. Most of the devices in this network, for example the personal computers, smartphones, digital cameras, tablets and digital

VANET integrates on multiple ad-hoc networking technologies such as Wi-Fi (IEEE 802.11), WiMAX (IEEE 802.16), Bluetooth, ZigBee etc. for easy, accurate, effective and simple communication between vehicles on dynamic mobility. In the past decade, VANET research has addressed all the layers, physical to application to support the design of

4. Methodology Used Soft computing methodology can be used for developing a model that can predict autonomic computing based software systems maintainability according to the opinions of experts of this domain. Soft computing is different from conventional hard computing as in hard computing we require full truth but in soft computing we can solve a problem with vague values and with partial truth [11]. Soft computing techniques are more suitable for real world problems and require very less computational
