AbsIract-This paper proposes a novel distributed service dis-architecture followed by all these protocols is like this: A sercovery protocol for Mobile Ad hoc Networks. The protocol is based vice advertises and registers itself to a service register that keeps on the concept of peer-to-peer caching of senice advertisements track ofthe networked services A standard solution to resource discovery in MANETS is to broadcast a service discovery request through out the network. If a node contains the service, it responds with a service reply. The protocol is guaranteed to discover a service if it is present in the MANET. Apart from the fact that it is inefficient in terms of bandwidth and resource usage (since the request has to be processed by all the nodes which have limited processing capability and battery power), it gives rise to the broadcast storm problem [14]. The other solution is for the services to advertise themselves to all the nodes in the MANET. Each node interested in discovering services caches the advertisements. The advertisements are matched with service requests and a result is returned. In this solution, the cache size increases with the number of services. Many of the nodes have limited memory and are unable to store all the advertisements and soon the cache gets filled up. This is also inefficient in terms of bandwidth usage, since the whole network has to be flooded with advertisements every subsequent time interval. We introduce a novel group-based distributed service discovery protocol (GSD) for MANETS, which does not have broadcast storm problem and efficiently uses network bandwidth and is guaranteed to discover a service (if present) in the MANET. Our solution exploits the semantic capabilities offered by the DARPA Agent Markup Language (DAML) to effectively dein
The GSD protocol REF is based on the concept of peer-to-peer caching of service advertisements and group-based forwarding of service requests.
