Routing and Information Security in Wireless Networks
Brief Description: This project carries work related to the infrastructure based network (GSM network) as well as infrastructureless network (Adhoc network). In GSM network, the message generated from a mobile phone is in plain text, which can be easily read and modified before it reaches to SMS centre. It is very necessary to secure the SMS in order to prevent it from the various attacks applied on the SMS. In Ad-hoc networks, all tasks of network set-up and maintenance have to be performed by the nodes themselves because of the absence of any fixed infrastructure. Since the nodes have a limited energy source, all functionalities need to be energy-aware, which in turn implies efficiency in both communicational and computational terms. Providing any reliable service over such a network requires a secure and well-functioning network. The routing needs to be secured in such networks as almost all nodes need to participate in the routing process (for efficiency reasons) and presence of one malicious node could easily have drastic consequences on the routing performance of the whole network. Thus, it is required to have a new ad-hoc routing protocol, which could ensure the security checks that are required to prevent malicious nodes from hampering the routing process via various attacks like black-hole attack, wormhole attack, eavesdropping etc.
