Software tool of NS-2 is used to modern network simulation. It introduced in software's Mobile IP, it has carried on the analog simulation using the NS simulation software to the wireless network's course of communications. And it calling NS's Nam animation window to carry on the simulation demonstration, and carrying on analysis of related data record documents.
The transmission control protocol (TCP) provides reliable transport services between end-points and enjoys predominant share as carrier of data traffic over Internet. Last mile wireless links have challenged TCP effectiveness because of fluctuations in link quality and relatively low data rates. These fluctuations cause major performance degradation in terms of reduced throughput, increased retransmission...
The usage of multimedia applications such as IP-TV and Video On Demand over wireless networks becomes more and more popular. In many cases the bandwidth of the wireless channel is the system bottleneck and thus it is important to increase the ability of wireless networks to provide a scalable service for multiple users simultaneously. The main idea proposed in this paper is based on a dynamic bandwidth...
Mobile IP allows a mobile node to maintain a continuous connectivity to the Internet when moving from one access point to another. However, due to the link switching delay and to the Mobile IP handover operations, packets designated to mobile nodes can be delayed or lost during the handover period. This paper presents a new control function called Extended Handover Control Function (E-HCF) in order...
Comparing to wire networks, there are many different characteristics in wireless environments, which make TCP congestion control mechanism is not directly suitable for wireless networks and many improved TCP congestion control mechanisms have been presented. But these improved schemes are not considered the influences to TCP senderpsilas packet sending rate by the wireless link corruption. However,...
