Abstract

"The paper describes the Context based service discovery protocol (CBSDP), a service discovery protocol build over the Ad hoc Context aware network architecture (ACAN), it is designed to solve the problem of discovering services in a highly dynamic ad hoc communications. CBSDP is a distributed system that provides the user with the ability to obtain services and information according to the context (location, time, situation, users, etc), it will automatically detects the available services through the existence sensors and context processing agents. The paper starts with a discussion of the traditional services discovery concepts, then the ACAN architecture. The complete design of the context based service discovery protocol is presented with the messaging and cooperation between the different agents in the environment. A service ontology build using Protoge2000 is used as the common language for understanding the different services available in the environment. The paper concludes with the implementation of the protocol over the 802.11 Wavelan network"
