In this paper we present a distributed self-organizing trust based clustering framework for securing adhoc networks. The mobile nodes are vulnerable to security attacks, so ensuring the security of thenetwork is essential. To enhance security, it is important to evaluate the trustworthiness of nodes withoutdepending on central authorities. In our proposal the evidence of trustworthiness is captured in anefficient manner and from broader perspectives including direct interactions with neighbors, observinginteractions of neighbors and through recommendations. Our prediction scheme uses a trust evaluationalgorithm at each node to calculate the direct trust rating normalized as a fuzzy value between zero andone. The evidence theory of Dempster-Shafer [7], [8] used in order to combine the evidences collectedby a clusterhead itself and the recommendations from other neighbor nodes. Moreover, in our scheme wedo not restrict to a single gateway node for inter cluster routing. |
