Ad hoc wireless network have been involved in the proposal of the future fourth generation mobile communication system. In ad hoc wireless network, mobile nodes communicate to others without any infrastructure such as fixed based stations or fixed routers. Mobile nodes may roam through any place at any time and try to reorganize their communicating topology. In order to communicate to another node, which is beyond its radio range, one of the multihop routing protocols is used for discovering a routing path. In this paper, we discuss the data transmission on single path routing and multipath routing. We simulated with DCF (Distributed Coordination Function) in IEEE802.11 MAC (Medium Access Control) layer and analyzed the data throughput in a slot time and data transmission delay with different levels of interfering and different number of path routing on our network topologies we construct. On multipath routing, we lead in Load Balance mechanism on choosing next mobile node on its path at transmitting frames. It not only guarantees that the less utilities of path we already built will not waste any resources but also reduce the unstable traffic load to achieve more stabilize and quality of transmission.
