- Abstract
- The advancement of mobile communications for the last few years has accompanied an increasingly extensive and diverse array of environments for TCP applications, which has led to a host of wireless TCP approaches that may provide more stability and ensure higher performance. In a heterogeneous network, as opposed to conventional wireless networks, a mobile node performs a handoff to another network cells with a different bandwidth and latency. Conventional wireless TCP schemes, however, are not capable of properly addressing sudden changes in round trip time (RTT) and packet loss resulting from handoffs within a heterogeneous network and do experience such problems as the waste of available bandwidth and frequent packet loss. As a solution to these problems, this paper proposes Freeze TCP version 2 (v2), an enhancement of Freeze TCP designed to dynamically obtain the available bandwidth in a new network cell. Comprehensive simulation study is conducted by using a network simulator, ns-2, to compare the proposed scheme to a few other schemes, such as Freeze TCP, DEMO-Vegas, and TCP Vegas, in a heterogeneous network environment with vertical handoffs in terms of throughput per speed of the mobile node and per bit error rate of the wireless link. © 2009 Springer Berlin Heidelberg.
