Security aware minimized dominating set based routing in MANET

Attacks on ad hoc network routing protocol affects network performance and reliability. Epidemic routing protocols are based on message flooding in the network which results in large number of lost messages. In this paper, we present a secure minimized dominating set routing protocol for mobile adhoc network based on delay tolerant network. In the proposed model, the route selection is based on concept of virtual network topology, where messages are routed only to trustable nodes in minimized dominating set. It includes techniques to: identify trustable nodes, calculate probability of future contacts between the nodes based on trust factor and time of contact. The route selection is considered as function of following parameters: trust level of the node, and probability of future contacts. The goals of secure minimized dominating set routing are to: i) maximize the message delivery rate, ii) Minimize the total resources consumed in message delivery, iii) secure the message content.
