The invention designs a mobile ad hoc network intelligent anti-loss device comprising a wireless ad hoc network module, a power module, a CPU, a Bluetooth transceiver, and a buzzer. An ad hoc network is formed automatically between two or more anti-loss devices to connect the anti-loss devices and carry out mesh network management. The mobile ad hoc network intelligent anti-loss device provided by the invention realizes interconnection between multipoint equipment and is especially applicable to a smart home system. The problem that the existing ordinary anti-loss device can only establish short-distance point-to-point connection, the alarm is raised once the signal is broken, only point-to-point connection can be realized, and a mesh network cannot be established automatically for ad hoc network management is solved.
