Abstract: A bracket, a module assembly, and an electronic device, so as to improve position stability of the module in the electronic device. Two first limiting parts arranged opposite to each other are arranged at two ends of the bracket, a second limiting part is arranged on at least one side of the bracket, and the two first limiting parts and the second limiting part are enclosed to form a mounting position for mounting the module. Both the first limiting parts and the second limiting part may limit the module, so as to limit in all directions and ensure position stability of the module in the bracket. The bracket is further fixed to the electronic device through fixing parts, so that the position stability of the module in the electronic device may be improved.

Abstract: A scalable, minimum node complexity, energy efficient, and error-resilient routing method for wireless sensor networks is described. The network is partitioned into regions by power controlled base station scans using a directional antenna. Routing is performed using only local location information and instructions received from the base station at each sensor node with minimum processing and control overhead, thus allowing simple, low-cost sensor designs. Sensors in the network provide to a base station reports of the condition of the sensors themselves, and these reports are analyzed by the base station to determine improved routing instructions, which are then provided to the sensor nodes in control messages. Each data packet is relayed in an interleaved, loop-free mesh of sectors toward the base station, making data delivery robust to sensor failures and transmission errors.
