Abstract: Disclosed is a scalable, hybrid mobile network termed the Metropolitan Area Mobile Network (MAMN) based on a new dynamic mobile network protocol-DynaMo. DynaMo supports TCP/IP based communication between nodes, whether they are moving or stationary. DynaMo is a location-based routing technique that integrates MAMN, with wired TCP/IP networks (such as the Internet). Through the disclosed use of a modified Domain Name Services (DNS), communication between wired and wireless nodes, moving or stationary, is supported and is transparent to the end-user. DynaMo supports the use of multiple channels and implements a scheme for channel reuse. A hybrid encryption mechanism, based on public/private key pairs enables signed and secure communication.
