Wireless ad hoc network (MANET) is a kind of network that can communicate without infrastructure. It has the characteristics of dynamic topology, limited bandwidth and constrainted terminal energy, and so on. These characteristics make the MANET impose many specific and strict requirements on routing protocols. In order to solve the problem of high packet loss rate and network congestion, a cross-layer routing algorithm based on congestion prediction (CLRACP) is proposed. In this algorithm, a congestion prediction mechanism is proposed, which makes high-load nodes do not need to forward routing request messages and effectively avoids high-load nodes being selected as forwarding nodes. A cross-layer routing algorithm is also proposed, which combines underlying link quality information to choose and select routing to improve the routing timeliness.
