Mobile Ad-hoc NETworks (MANETs) are prone to many security attacks and risks due to its characteristics such as mobility, lack of infrastructure and dynamic topology changes. In this paper, the authors propose CBDAT, a cross layer based detection and authentication technique for MANET. Their technique defines the observer node to monitor the neighbor transmissions and to compute the trust values. The observer node is elected considering residual energy, node degree and stability information. The trust value is protected using Message Authentication Code (MAC). The estimated trust value is used for selecting the best path among the multiple paths between the source and the destination pairs. The selected path information is forwarded to Media Access Control (MAC) layer to allocate access time.
