Abstract: Service discovery is difficult in Ad hoc network. Aiming at this problem, a protocol for Ad hoc called ESDP(Efficient Service Discovery Protocol) is proposed after analyzing the current service discovery protocols. It is designed at application layer and is an integrity of pull and push mode. The mechanisms of cache, back off and cooperation between devices etc are adopted to reduce transmitting. Energy consumption is saved by reducing the cost of transmitting. The heterogeneity of devices and security are considered. Network simulation and analysis show good performance of the protocol.
Key words:
service discovery,
heterogeneity of devices,
nodes cooperation
