Location service is an efficient solution to handle actor mobility in wireless sensor and actor networks. In previous works, the information that the actor updates to location servers is its latest location. However, in most applications, the actor knows its own mobility strategy, such as its destination, trajectory and speed. If the actor can share its mobility strategy in the update packet, it will be helpful to improve the performance of location service. In this letter, we propose a mobility strategy sharing location service protocol called MLS, to show the description of mobility strategy in the update packet and its utilization for routing. The theoretical analysis and simulation results show that, sharing mobility strategy greatly reduces the update overhead and improves the scalability of MLS.
