Effect of Node Mobility and Handoff on the Performance of Tcp Variants in Mobile Cellular Environment
نویسندگان
چکیده
TCP is the most common and important transport layer protocol and its performance in the wireless environments is characterized by two path characteristics not normally present in wired environments: packet losses due to corruption and mobility.. In this research, we have used the perfect cellular model to model the wireless packet losses due to mobility and handoff in order to get the real performance of TCP. In this paper, we have investigated the behavior of TCP Tahoe, Reno, New Reno, Sack and Vegas in a Cellular Mobile network and tried to find out the impact mobility and handoff of mobile node on the behavior of these TCP variants and which TCP variant has the best performance among all the TCP variants considered in this research.

Improving TCP Performance in Mobile Ad Hoc Networks Using Mobility Prediction
In mobile ad hoc networks node movements induce frequent topology changes. Therefore, traffic paths are often interrupted, until an ad hoc routing protocol recovers the path failure. These disruptions have negative impact on the network throughput, particularly when the transport protocol is TCP. In this paper we analyze the effect of route disconnections on TCP performance and present a routin...
متن کاملWi-TCP: A TCP in Wireless Environment
Due to the strong drive towards wireless Internet access through mobile terminals, it has become necessary to carefully handle the issues in the wireless environment such as frequent handover/handoff (user mobility), temporary disconnection, burst error and fading. These characteristics of wireless environment deteriorate the performance of wireless systems sharply in terms of TCP throughput as...
متن کاملEffect of High Error Rate on the Behaviour of TCP Variants Using Realistic Error Model in Cellular Mobile Environment
TCP performance in the wireless environments is impacted by two path characteristics not normally present in wired environments: packet losses due to corruption and mobility. There are two mechanisms to model the wireless packet losses in simulation: Uniform error model and the Realistic error model (Two states). Uniform error model tends to produce inaccurate results, because in this error mod...
متن کاملPerformance Evaluation for Mobility Management Protocols in Cellular IP and Hawaii Mobile Networks
Handover management is one of the most critical issues that mobility management protocols are concerned with. This process becomes even more critical in the case of Micro-mobility where the Mobile host is expected to encounter frequent handovers. Several IP micro-mobility protocols have been proposed to enhance the performance of Mobile IP in an environment with frequent handoffs. In this paper...
متن کاملModeling IP-Based Mobility Management
Mobility of a phone within a cellular network or of a computer within the Internet has to be managed by the respective network infrastructure: Routes to and from a mobile device have to be changed. In order to base mobility management of future cellular networks on IP, the Internet Protocol, various proposals like Mobile IP are currently being discussed. In this paper, we develop a simple model...
