Abstract
Service discovery is essential in any network. When it comes to a self-sustained network like mobile adhoc network with limited resources it is even more essential. A service could be any hardware or software that the user is interested to access. The process of Service discovery should enable a consumer to discover a service provider and access those services in an efficient and scalable manner.
The AODV protocol was extended to perform service discovery along with route discovery. This protocol was further extended to include service advertisement by modifying the Hello messages. We propose a method to improve the performance of the network during service discovery by using hello messages to collect routing and service information of neighbour nodes at a two hop distance. Instead of storing the complete information about the services only the availability or non-availability of services are stored. So it does not increase the storage overhead. This information reduces the traffic in the network and thereby reducing the number of packets dropped.
