Patent ID: 11729659

Abstract:
A cross-layer security scheme can be used for a Multi-Input Multi-Output (MIMO) antenna-based large-scale multihop mobile ad hoc network (MANET) with a set of frequency-nonselective, slow/Rayleigh fading, and uncoded channels along with interference combining both physical, link, and higher layer encryption techniques for the payload in addition to signaling. Furthermore, MIMO-aware cross-layer secure MANET physical and key-based logical hierarchical routing proving scalability can be used. Security can be provided in Multi-Hop MIMO MANETs in Physical, medium access control (MAC), and internet protocol (IP) Routing layer. The MIMO-aware MANET IP Routing can include two kinds of routing: Physical Routing such as secure ad-hoc on-demand distance vector (SAODV) in the access MANET and Secure Key-based distributed hash table (DHT) “logical” routing in the backbone MANET. Both security and performance metrics can be employed to improve (e.g., optimize) both network secrecy and throughput/bandwidth capacity.
