It has become known that the traditional layered approach that separates routing, flow control, scheduling, and power control is suboptimal in wireless ad hoc networks. Nodes in an ad hoc environment face two major challenges: the mobility and the resource constraints. In a cross-layer design, the control over two or more layers can yield significantly performance improvement. Cross-layer based routing using forwarding node selection (CRNS) is proposed to adapt to the state of the network. In CRNS, each node maintains a table for its neighbors and selects its own route request forwarding nodes based on the state of the portion of the network surrounding it. The forwarding nodes have been selected according to the number of neighbors and their power of received hello message broadcasted by the neighboring nodes. The CRNS protocol has been implemented and evaluated and compared with well known protocol AODV using Glo-MoSim simulator. Extensive performance analyses including study of impacts of node density and node mobility have been performed. Results have revealed that the performance behavior of the CRNS routing protocols has significantly been improved.
