Abstract :
Most of routing protocols for wireless ad hoc networks are based on the hypothesis of symmetric link. However, because of the influence from radio power, battery outrage, and environment and so on, asymmetric link is prevalent. At present, projects to solve this problem are mostly set tables of immediate neighbors and indirect neighbors, and use the corporate neighbors to inform the node whose region is larger. In this paper, we solve the problem of asymmetric link in the way to change the frame structure and transmit mechanism of the IEEE802.11 protocol. And get the same effect without building the table of neighbors.
