Secure dominating set-based routing protocol in MANET: Using reputation

Mobile ad-hoc networks (MANETs) face a number of challenges, in particular due to its dynamic network topology. A self organizing framework can overcome the problems associated with changing topology and dynamic behavior of mobile nodes thus routing has become a great challenge to these types of networks. Such a framework can be created by using connected dominating set (CDS). But the choice of misbehaving node as CDS will inversely affect the network performance. A misbehaving node may disturb the network by denying packet forwarding. In this paper we propose a new reputation based routing protocol using CDS (Connected Dominating Set). The proposed weight heuristic is applied to each node in network for selecting CDS based on uses the reputation value in order to selective forwarders detection. Reputation refers to the opinion of one node about another node. Hence only well behaving and good quality nodes are selected as a dominant node for CDS construction. Through simulation results proves that the proposed method performs well compared to MPR selection approach in OLSR.
