Abstract
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. There is no central node for controlling entire network. So routing in MANET is very important.
In content based routing, data is transferred from source node to requested nodes is not based on destinations addresses. Therefore it is very flexible and reliable, because source node does not need to know destination nodes. 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 routes on the network. So when a node publish a request to get some content, it will prepare a subscription message then broadcast it to network. When any node on network received that subscription, it matches subscriptions content with published content that have been cached on it. If found then matched content will be transferred to requested node. There is another routing model when nodes have content requests, they broadcast subscription messages to network. When nodes receive subscriptions, they cache these messages. When a node publish its content by broadcast protocol, any node receives that content, it will match received content with subscriptions cached on it to find all nodes have requested that content, then forwarding that content to these nodes.
Service Oriented Routing is inherited from the model of content based routing (CBR) [3, 4], combined with several advanced techniques such as Multicast increase the data rate [6], and data encryption to ensure information security.
This article presents some techniques to support multicast packet forwarding from one network node to a set of nodes with guaranteed quality of service. By using these techniques can decrease network load, congestion, use network resources efficiently.
