The Content Centric Networking is scalable and efficient in the Internet, it raises concerns when deployed in a mobile large scale network like the Vehicular Ad-hoc Network (VANET). However, many applications in multi-hop ad-hoc vehicular networks are push-based and require fast communications. The CCN's pull-based transport in such cases may backfire, underperforming and costly without careful design. According to method for reducing the network cost caused by overheads and congestion. In this paper we firstly propose a service discovery scheme then optimize the number of vehicles which cache the matching data for a certain interest in the Content Store (CS), while satisfying the requirement of delay. We model this problem as optimization problem and we prove this problem is NP-Complete. Then we develop a heuristic algorithm to solve this problem according to the normal distribution property.
