文摘Mobile multihop communication network is an important branch of modern mobile communication system, and is an important technical support for ubiquitous communication.

Aiming at the problem of declining link duration caused by nomadic characteristics in mobile multihop communication network, four link duration models for possible moving states are established based on different features in real networking process in this paper, which will provide reliable criterion for the optimal routing selection.
