TODO - The operation of TCP in wireless-mobile environments is discussed in
this paper. After briefly presenting previous efforts to ameliorate TCP
performance in the considered environments, we propose a new mechanism
for tackling the slow-down, problems caused by handovers. Our mechanism
is based on stochastic datagram relocation. Traffic destined to the
mobile terminal is tunneled to and cached into adjacent cells according
to the output of a path prediction algorithm. To reduce the associated
overhead, only percentages of inbound traffic are copied to the cell’s
neighborhood on the basis of estimated probabilities. The time
scheduling for datagram relocation is also taken into account.
Simulations of the proposed architecture show substantial performance
improvements for TCP traffic. (C) 2002 Elsevier Science B.V. All rights
