Transmission Controller: this module is the main function used to manage data transmission (send/receive) to other motes within the network connectivity via AMSend (a packet transmission interface with data payload to specific mote addresses). Receive (the functional interface working in the opposite direction of AmSend, with A Packet-de/encapsulation interface for sensor data as well as specific header information included in the module), Boot (an initialization interface), and finally, SplitControl (a switching interface between the on and off power states).
