摘要： Methods for maintaining continuing existence of a next-in-line protecting device in a beacon network including a primary protecting device (PPD), the next-in-line protecting device (NPD) and a plurality of secondary protecting devices (SPDs). In one method, a subset of the plurality of secondary protecting devices periodically transmit beacon messages to the primary protecting device. When the next-in-line protecting device disappears, the primary protecting device selects a secondary protecting device from among the secondary protecting devices that have transmitted the beacon messages within a certain period to be a new next-in-line protecting device. In another method, the plurality of secondary protecting devices continuously monitor an existence of the next-in-line protecting device. When the next-in-line protecting device disappears for a certain period of time, a subset of the plurality of secondary protecting devices may contend to be a new next-in-line protecting device. In still another method, the primary protecting device transmits a beacon message to the plurality of secondary protecting devices to indicate whether a next-in-line protecting device is required. When a next-in-line protecting device is required, a subset of the secondary protecting devices contend to be a new next-in-line protecting device.
