A trust based secure gateway selection and authentication scheme in MANET
Amit Kumar Gupta, Rakesh Kumar, Naveen Kumar Gupta · 2014
Mobile Ad hoc Network (MANET) is a collection of self-configuring, infrastructure less mobile nodes that dynamically form a temporary network and capable of communicating each other without the use of network infrastructure. Due to the open medium, dynamic topology, distributed co-operation Ad hoc networks are vulnerable to many type of security attacks. An important concept in network security is trust; it is estimated as a relation among the entities that participate in various protocols. Trust relations are based on evidence related to the previous behaviour of entities within the protocol. In this paper we focus an trusted route selection value between mobile node and secure gateway which is based on trust values of nodes, trust value of route and residual route load capacity and we also focus mobile node and secure gateway authentication process which is based on pre-authentication technique. To provide a host-to-host security, it is important to evaluate secure trusted route towards the secure gateway and authenticate mobile node and secure gateway. It can be achieved in proposed scheme. Our proposed protocol provides better performance as compared to other protocols. The correctness of our proposed scheme is validated through simulation results and performance evaluation matrices.
