Analyzing AODV in a Hybrid Security Mechanism

Abstract

Mobile ad-hoc network is used for communication between the short range devices without having any infrastructural
support.All mechanisms proposed for security aspects, must be aware of these parameters and don’t disregard them, otherwise they may be useless in MANET. Here the devices directly exchange the data and routing information • between neighbourhood devices which was there in defined range. Such network lacks with centralized controls and hence the information regarding the nodes leaving the range or nodes coming into the ranges are maintained by each node in their routing tables. In some situations, dynamic topologies and heavy movement causes security degradations because to verify the authenticity of each node participating in communication is not possible. Thus to have effective authentication and confidentiality is became a challenging task. This work uses RSApublic key cryptosystem and • SHA-I as digital signature for verification of hash codes of identity information’s. It is capable of handling both the information of data and control packets. After the robust analytical evaluation and quantitative measurement the effectiveness of the tool and its workability is verified.
