Mobile ad hoc network (MANET) is an infrastructure less network, in where all mobile nodes are free for any movement to any side. Thus the network is going toward zero configurations that would create some problems. Ad hoc network is faced with various limitations that need to be considered among design and implementation of any protocol for it. Service discovery (SA) is one of the important services that are offered in each network because, to have a fast service discovery in a network with minimum energy consumption, distributing of services’ information and their management play important rolls. In this paper for avoiding packet flooding in the MANET we used Cluster Based Routing Protocol (CBRP). For reducing amount of communication messages we moved service advertisement from application layer to routing layer. Thus we distribute the active services in the network among clustered nodes. The results of our experiment show that our method does not add any extra overhead to the network.
