ENHANCEMENT OF QOS OF VOIP IN HETEROGENEOUS NETWORKS B.Balavenkatesh Abstract— The increasing demand for broadband services is causing the cellular network providers to consider for the integration of Wireless LAN with GPRS. WLAN is having higher data rate but low coverage area but GPRS is having lower data rate but with high coverage area. So integrating these two heterogeneous networks will lead to utilization of advantages of both and can increase the system throughput. The handoff latency

increasing day-by-day‚new methods for wireless networking has been evolved of which our present topic Wi-Fi is the most accepted technology. Wi-Fi‚ an acronym for Wireless-Fidelity which is the wireless way to handle networking.The main aim of this paper is wireless networking achieved by Wi-Fi.This paper introduces Wi-Fi technology and states the history of this technology in brief.We then deal with the different ways of wireless networking‚connecting wi-fi and with

Wi-Fi as any "wireless local area network (WLAN) products that are based on the Institute of Electrical and Electronics Engineers’ (IEEE) 802.11 standards".[1] However‚ since most modern WLANs are based on these standards‚ the term "Wi-Fi" is used in general English as a synonym for "WLAN". A device that can use Wi-Fi (such as a personal computer‚ video game console‚ smartphone‚ tablet‚ or digital audio player) can connect to a network resource such as the Internet via a wireless network access

Establish a Wireless Security Policy. Gartner study shows that security risks are more from internal users than from external users. Many a time people creates security risks to network simply because of ignorance. While securing a wireless network‚ we need to create a wireless security policy and train users before they start using wireless network. The security policy should include “Acceptable uses”‚ Uses of “Antivirus”‚ use of “Host based Intrusion Prevention System” 2. Separate the Wireless LAN from

Introduction: Now-a-days we are living in a technical era where almost all electrical products are functioning wirelessly. There are different types of protocol used for wireless communication. In this paper I am going describe about some wireless protocols use all over the world. At first we have to know what protocol is. And why it is important for communication pattern. Then I tell about drawbacks and finally there will be my assumption about different protocols. Description:
