The time difference measurement unit measures a time difference between a first time based on latest received time information and a second time based on second-latest received time information. The time setting unit calculates an adjustment time difference when the time difference exceeds an allowable range of error that is smaller than an allowable range of maintainable communication, sets a time obtained by adding the adjustment time difference and the second time to the time of the node when the adjustment time difference is within the allowable range of maintainable communication, and sets a time obtained by adding a time difference corresponding to the allowable range of maintainable communication and the second time to the time of the node when the adjustment time difference exceeds the allowable range of maintainable communication.

Abstract: A terminal used in a network that constructs a communication route with ad hoc communications is connected to a server via a gateway. The terminal generates downstream route information from the server to a specific terminal based on information relating to occurrence of downstream communication from the server to the specific terminal, the information being included in a header of upstream communication from the specific terminal to the server, and preferentially retains the downstream route information.

Abstract: In an embodiment, conductance of electricity to a heating element (4) for heating a throttle valve (2) of an automobile engine and a peripheral section thereof is performed only during a period wherein this heating can be performed effectively. Specifically, a controller (53) receives an output signal from an air flow sensor (54), and when a quantity of intake air is equal to or less than a predetermined “intake air quantity criterion for heating”, conduction of electricity to the heating element (4) is carried out. Conversely, when the quantity of intake air is greater than this “intake air quantity criterion for heating”, conduction of electricity to the heating element 4 is prohibited.
