MANET (short for Mobile Ad-Hoc Network) consists of a set of mobile network nodes, network configuration changes very fast. Each node will act as a router to maintain network operation. As some standard content based routing protocols, when a node publishes its content, it will broadcast data to network. The published content will be cached at all routers on the network. So when a node publish a request to get some content, it will prepare a subscription message then broadcast it. When any node on network received that subscription, it matches subscription's content with published content that have been cached on it. If found then matched content will be transferred to requested node. Service Oriented Routing is inherited from the model of content based routing (CBR), combined with several advanced techniques such as Multicast, Genetic algorithm (GA) increase the data rate, and data encryption to ensure information security.
