Abstract

Communication network architectures, systems and methods for supporting a network of mobile nodes. As a non-limiting example, various aspects of this disclosure provide communication network architectures, systems, and methods for supporting a dynamically configurable communication network comprising a complex array of both static and moving communication nodes (e.g., the Internet of moving things). For example, a communication network implemented in accordance with various aspects of the present disclosure may support transmission power adaptation in a network of moving things comprising various fixed nodes, mobile nodes, and/or a combination thereof, which are selectable to achieve any of a variety of system goals.
