TCP-Jersey for Wireless IP Communications
Kai Xu, Ye Tian, and Nirwan Ansari, Senior Member, IEEE
Abstract--Improving the performance of the transmission
control protocol (TCP) in wireless Internet protocol (IP) com-
munications has been an active research area. The performance
degradation of TCP in wireless and wired-wireless hybrid net-
works is mainly due to its lack of the ability to differentiate the
packet losses caused by network congestions from the losses
caused by wireless link errors. In this paper, we propose a new
TCP scheme, called TCP-Jersey, which is capable of distinguishing
the wireless packet losses from the congestion packet losses, and
reacting accordingly. TCP-Jersey consists of two key components,
the available bandwidth estimation (ABE) algorithm and the
congestion warning (CW) router configuration. ABE is a TCP
sender side addition that continuously estimates the bandwidth
available to the connection and guides the sender to adjust its
transmission rate when the network becomes congested. CW is
a configuration of network routers such that routers alert end
stations by marking all packets when there is a sign of an incipient
