Wireless Ad hoc network is a network, which does not have any geographical restriction and fixed substructure. This kind of networks are divided into cellular and special networks. Cellular networks are comprised of a fixed spinal column and a radio-base station. When a node exits from the domain of base station and reconnects to another station, it continues to function. In this method, the base station is fixed but the connection of Special Network does not have a predetermined structure. Administration and configuration of these kinds of networks are not dependent on any special user. Such networks back up calculation at any time and in any place and their structures can change automatically. In special networks since all of the nodes are mobile and connect dynamically they are commonly named Ad hoc. There is increasing trend for applications in such fields as mobile vehicular communication, special field tasks and distributed mobile automation systems. In this kind of network, all of the nodes act as routers; they find paths and keep other nodes' information. In this paper, we discussed special networks, improved their routing protocol called DSR (unicast), and introduced new protocol named GBDSR (multicast). GBDSR allows a node located in the network to send data packets for other nodes. In GBDSR, multi distribution of data packets are turned into general distribution of data packets. This leads to have a new protocol with less network traffic, less access time, less packet loss and less energy usage. Of course, these advantages need more use of bandwidths.
