| Summary: | 碩士 === 國立東華大學 === 電機工程學系 === 95 === While the technologic of Wireless development rapidly in recent years. Most of electric produce can connect to internet by WI-FI. But the WI-FI Coverage fractions still not enough to provide a lot of user. MANET is getting more seriously concerned in public, because of it doesn’t need centralize management equipment and MANET constructs a network rapidly. So people start thinking，we have so many application for MANET. We also need a mechanism to help us easily to find application which we want.
Service Location Protocol [2] [3] is the popular of Service discovery protocol. Service Location Protocol for MANET that has many problems must to overcome， such as Power Consumption, dynamic topologies and limited bandwidth.
This paper presents an adaptive method which use cache stored the directory agent’s (DA) formation. When User agent (UA) or service Agent (SA) broadcast service request which discovery DA. The neighbor nodes will receive this request and check. The neighbor node which has DA cache will send back the DA cache. Our propose improvement the overhead、service discovery efficient and successful ratio.
