Routing and MAC Layer based Framework for Secure and Reliable Communication in Mobile Ad Hoc Networks

The research outlines three novel methods of detecting malicious nodes, which include Cumulative Frequency Detection, Data Forwarding Behaviors Detection, and MAC-based Authentication. These algorithms are used in ensuring reliable security for the Mobile Ad hoc Networks (MANETs). The purpose of Cumulative Frequency Detection is to determine indications of activities as a DoS attack or a heavily loaded channel. This is achieved by adding the total number of clear to send (CTS) and request to send (RTS) packets relayed by the channel over a particular time interval. The Data Forwarding Behaviors Detection is a database-based trust values to find the relationship between forwarding nodes and to modify the routing algorithm based on it and exclude the suspicious or untrusted nodes. The MAC Based Authentication process uses the Message Authentication Codes (MACs) in the shared key cryptographic system to authenticate the request and the response. The issues that are associated with the unauthorized nodes may be resolved in line with the application of the above Combined Solution for Routing and MAC (CSRM) layer attacks, as explained in the paper. Therefore, there is less control overhead and low loss of packets during the transmission in wireless communication. This also improves the security aspects and makes a connection to another MANET irrespective of the hostile, dynamic and unpredictable nature of the network environment.
