Analysis of TCP performance over mobile ad hoc networks
... Therefore, the expected throughput for a given mobility pattern, calculated using Equation 1, is independent of the speed. Intuition suggests that when the speed is increased then route failures happen more quickly, resulting in packet losses, and frequent route discoveries. Thus, intuitively, TCP t ...
