The emergence of MANET supported applications and the subsequent widespread acceptance is facilitated by the development and availability of cheap wireless Wi-Fi devices. It is on this premise that Flow-Aware Admission Control (FAAC) protocol is designed to improve the throughput assurance of MANET-based applications. The work presented in this paper is an extension of our designed FAAC protocol to guarantee the provisioning of QoS in many mobile scenarios. The source node is designed to maintain multiple paths to each destination with the reliability of the routes maintained through nodes disjointness. The designed FAAC-Multipath protocol is equipped with the intermediate route repair mechanism to enable the intermediate node to carry out route repair locally without contacting the source node. We have illustrated the effectiveness of FAAC-Multipath with the state of the art admission control protocols.

Privacy, Anonymity, pseudonymity are the debatable terms which on one angle restrict the rights but on other angle open doors for malicious activity.This paper proposes design for a pseudonymised communication which is optimal solution for the privacy issues, where the real identity is hidden from the outside world by using blind signature in a different way of group communication.The protocol is deployed and analysed in extreme environment of Delay Tolerant Networks (DTN), which is overlay on the top of traditional Internet which provides end to end connectivity and characterized with long delay and disruption. A telemedicine application of rural area network is explored to provide source anonymity.The protocol is finally analysed using Dolev Yao model with two different cases and it preserves the original identity of the node.
