D2C2 - DYNAMIC AND DESERTION BASED CREDIBLE COMMUNICATION IN MOBILE AD-HOC NETWORKS

Abstract

Mobile ad-hoc networks (MANETs) assume that mobile nodes voluntary cooperate in order to work properly. This cooperation is a cost-intensive activity and some nodes can refuse to cooperate, leading to a selfish node behavior. Thus, the overall network performance could be seriously affected. Many message authentication schemes have been developed, based on either symmetric-key cryptosystems or public-key cryptosystems. Most of them, however, have the limitations of high computational and communication overhead in addition to lack of scalability and resilience to node compromise attacks. Many anonymity
enhancing techniques have been proposed based on packet encryption to protect the communication anonymity of networks. In This Project we used RKP (Random Key Pre- distribution). We propose a key pre-distribution scheme that relies on probabilistic key sharing among nodes within the sensor network. Key pre-distribution is the method of distribution of keys onto nodes before deployment. Therefore, the nodes build up the network using their secret
keys after deployment, that is, when they reach their target position.
