Abstract:
1. A method of enabling a first wireless device to rendezvous with at least a second wireless device through a wireless network, where activation schedules of the first wireless device and the second wireless device are not synchronized, the method comprising: pre-determining by the first wireless device a number of time units in each cycle of a plurality of communication cycles; creating an activation sequence having a plurality of active time units in each cycle during which the first wireless device enters an active mode and a plurality of inactive time units in each cycle during which the first wireless device enters an inactive mode, a sum of the plurality of active time units and the plurality of inactive time units equaling the number of time units in each cycle; and controlling the creating such that a first active time unit of the plurality of active time units in each cycle occupies a same position in the cycle as an active time unit in a previous consecutive cycle, and a second active time unit of the plurality of active time units in each cycle occupies a different position in the cycle than any active time unit in the previous consecutive cycle.
