Abstract
A method for a hybrid service discovery adapting between push-based and pull-based schemes in a mobile ad-hoc network and a system thereof. The method includes periodically transmitting a first control packet for providing service information from a service provider that is capable of providing a service to nodes located in a specified advertisement zone, transmitting a second control packet requesting the service from a service demander to one or more nodes in a network, and transmitting a third control packet including path information of the service provider if at least one of the nodes located within the advertisement zone and the service provider receives the second control packet. The method and the system can reduce the amount of control packet transmission and minimize an end-to-end delay.
