A Three Layered Peer-to-Peer Energy Efficient Protocol for Reliable and Secure Data Transmission in EAACK MANETs

摘要

In a wireless adhoc network packets may be dropped due to the high node mobility. This network behavior undermines the network credibility to successfully route messages. Packet dropping may also be due to the presence of malicious nodes. Also, maintaining a viable route for the packets to travel is a greater challenge as it involves discovering a route and maintaining it for the entire session. It is very important to resolve these issues in order to maintain the performance of an EAACK MANET (Enhanced Adaptive Acknowledgement). The performance of a MANET rests heavily on its successful transmission rate. In order to have a high success rate all of these three issues need to be addressed. We have proposed a protocol (FDCRP) that would incorporate an efficient three layered framework into an EAACK MANET to ensure a high transmission rate. In order to include this framework into EAACK MANETs, the network would be divided into clusters. To manage the high mobility of the nodes and to form clusters faster, we use the node information efficiently. This technique involves the use of fuzzy logic and helps form clusters dynamically. We also incorporate a three tier filtering scheme to isolate the trusted nodes in forming a cluster, as there is a heavy possibility that the cluster nodes or even the cluster head turning malicious in the course of a transmission. The third level of our framework would address the issue of discovering better routes for the packets to reach their destination. This scheme would use the subset of intermediate clusters along the route to deliver the packet successfully to its intended destination. The proposed protocol would be capable of addressing multiple issues in EAACK MANETs thus maximizing the overall performance of the network.
