MANET supports communication without any wired medium and with layered architecture. It does not
uses any infrastructure support. Present alternative to the layered architecture is cross layer design
approaches and the interaction between the layers is supported. The security of CLPC (Cross Layer Design
Approach for Power control) routing protocol will be discussed in this paper. The transmission power and
finding the effective route between source and destination can be improved by CLPC. The reliable path
between the source and destination can be determined by RSS from the physical layer, but it is vulnerable to
the DOS attacks. Here we propose a Secure cross layer power control protocol SCLPC to placate the attacks
on CLPC. The SCLPC protocol provides better results and performance.
