Abstract The motion of node leads to the real-time changes of the topology of mobile ad works, and increases plexity of routing. The existing stability-based routing algorithms always focus on how to establish a stable route, which have ignored the adaptability of the established stable route to the motions of nodes. Aiming at this problem, a mobility-adaptive strategy for stability-based routing is proposed firstly. This strategy mainly contains three key technologies;the bidirectional evaluation of the stability parameter during route discovery process;the asynchronous information and the link stability update when node changes its motion state;And the multi-path route maintenance based on link stability. Then based on the mobility-adaptive strategy, a mobility-adaptive stability-based on link routing algorithm is also proposed. The simulation results show that the proposed mobility-adaptive strategy and stability-based routing algorithm can improve the routing performances further, and adapt to the dynamic mobile ad work environment better.

1 Introduction
Mobile Ad works is the work consists of mobile anizing nodes. munication in work is achieved through the multi-hop path made up of a set of nodes. However, mobility of nodes will cause the interruption of transmission path, leading to the decline munication performance.
To meet the requirements of application, researchers raised a lot of s routing algorithms which support quality of service. Stability-oriented routing algorithm is important among them, aiming at improve the stability and constancy in the process of data transmission, reducing the effect on routing caused by node mobility. In NSR, nodes whose neighbors change lest has better stability, so a
