摘要：A mobile ad hoc network (MANET) is a system of wireless mobile nodes with routing capabilities, any group of them capable of forming an autonomous network that requires no infrastructure and is capable of organizing itself into arbitrary changeable topologies. A MANET needs a special mechanism to bear with its ad hoc behaviour. In this paper, we are considering a set of heterogeneous nodes in MANETs, which are having different packet size, different security mechanisms and different communication speed etc. The architecture we propose comprises of two main building blocks, namely security management and communication management across all heterogeneous nodes in the scalable and non scalable MANETs. In this network each node does not understand security techniques of each other nodes, because, there could be different encryption techniques, packet size, protocol etc, hence this network is fully dependent on middleware of MANETs. The proposed solution provides security solutions in middleware for scalable and non scalable MANETs and it has found that the malicious node would not be a part of communication in the network through simulation. This technique is very effective for security issues in heterogeneous nodes in MANETs.
