Verification and Innovation of Neighbor Positions in MANETs?

In this paper generally MANETs are self-configuring autonomous networks that do not need any central authority to control and coordinate the network. In this neighborhood discovery (ND) is the process of discovering the devices that are directly reachable for communication or in physical proximity. So it becomes a fundamental requirement and building block for various other applications. It is very easy to abuse ND and there by compromise the overlying protocols and applications. Thus, providing methods to mitigate this vulnerability and secure ND is essential. This paper uses the directional antenna algorithm called as scanning based direct discovery algorithm to discover the neighbors, and location awareness is an important asset in mobile systems and many protocols require knowledge of position of the participating nodes. To allow cooperative working of the variety of distributed protocols we use trust system to provide the trust level of various nodes, thereby enhancing the cooperation amongst the nodes. This paper uses distributed hybrid trust algorithm and as well uses relationship maturity concept to compute the trust of the nodes. This paper demonstrates that Trust systems are better than already existing cryptographic techniques.
