TCP Throughput Optimized Handover Decisions

چکیده
We consider a mobile user in an environment characterized by a cellular network with whole coverage and isolated Wireless-LAN (WLAN) access points. Downloading a file from the Internet, the user is often confronted with the need to come to a decision whether to handover from the cellular system to a WLAN access point. For offthe-shelf Mobile-IP configurations we show that the overall performance of a handover to WLAN and back depends on two main parameters only. Estimating these parameters at entering the WLAN coverage lets us derive a handover decision based on the overall performance seen by the user. We show in simulation that this handover algorithm performs well in differentiating between beneficial and decremental handovers.

Evaluating Multipath TCP Resilience against Link Failures
Standard TCP is the de facto reliable transfer protocol for the Internet. It is designed to establish a reliable connection using only a single network interface. However, standard TCP with single interfacing performs poorly due to intermittent node connectivity. This requires the re-establishment of connections as the IP addresses change. Multi-path TCP (MPTCP) has emerged to utilize multiple ...
متن کاملAnalysis and Performance Improvement of TCP during the Handover of LTE
Within the Third Generation Partnership Project (3GPP), the new project entitled Long Term Evolution (LTE) is going to be a new standard. LTE is characterized by a broadband optimized radio access network, which focuses on supporting a high throughput with low latency by an ip based transport network. During the handover, which is the procedure to disconnect a mobile user from a base station an...
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 کاملTCP Throughput Improvement over Vertical Handover between 3G LTE and WLAN
We address TCP throughput degradation over vertical handover between 3G-LTE and WLAN. 3G-LTE link layer tries to recover packet loss and deliver recovered packets in-order. This may involve link layer holding packets before later arriving packets arrive, causing spurious timeout. A stateof-the-art scheme holds fast retransmit/recovery for one RTT waiting for packets arriving at TCP layer out of...
متن کاملCross-layer Optimized Vertical Handover Schemes between Mobile WiMAX and 3G Networks
Nowadays, wireless packet data services are provided over Wireless MAN (WMAN) at a high data service rate, while 3G cellular networks provide wide-area coverage at a low data service rate. The integration of mobile WiMAX and 3G networks is essential, to serve users requiring both high-speed wireless access as well as wide-area connectivity. In this paper, we propose a cross-layer optimization s...
