CBSRP: Cluster based secure routing protocol

A Mobile Ad hoc Network (MANET) is temporary, transient and infrastructure less. This kind of network plays inevitable role in the different domains of wireless communication such as remote areas, disaster areas and military activities. Routing overheads, integrity, authenticity and secure data transmissions are some of the challenges of MANETs. Proposed CBSRP is a cluster based approach to decrease the routing overheads and concerns on secure data transmission applying Shamir´s secret sharing method. For message encryption and decryption the proposed protocol uses RSA-CRT algorithm. Simulation results, evaluate that the performance of CBSRP is more stable compared to other existing routing protocols, even in the presence of malicious nodes.
