More particularly, To a dynamic communication protocol support system, method and object communication device for providing information for operating an appropriate communication protocol.
In the case of object communication devices operated in a constrained environment such as underwater, underground, or mountainous areas, various sensors and communication modules are generally mounted. In particular, a communication device having mobility in a constrained environment requires a communication protocol operating policy suitable for each environment on the move.
However, in the case of conventional object communication devices, there is a problem that various hardware and software configurations related to communication protocols and operation policies for various communication environments must be mounted in order to operate in heterogeneous constrained environments. Since each layer of the communication protocol must perform the function of collecting the respective communication environment information redundantly, an overload due to the mounting of the communication protocol redundancy function occurs.

In addition, not only the movement of the object communication device to various constraint environments, but also the disadvantages of application in a field where real-time communication is required, such as when a disaster occurs and the conventional communication network becomes incommunicable, is revealed.
