New System Security Model for a Mobile Operator?s Meshed Access Network

Sharad Kumar Verma, Dr. D.B. Ojha

A MANET is an autonomous collection of mobile users that communicate over relatively bandwidth constrained wireless links. Since the nodes are mobile, the network topology may change rapidly and unpredictably over time. The network is decentralized, where all network activity including discovering the topology and delivering messages must be executed by the nodes themselves i.e., routing functionality will be incorporated into mobile nodes. Such networks are more vulnerable to security attacks than conventional wireless networks. The main objective of this paper is to presents a description of the new security model for the 3rd generation mobile network architectures for the case of wireless mesh backhauls.
