Specification of a frequency agile dynamic spectrum access TDMA method

摘要

Dynamic spectral assignment in an ad hoc network of wireless network nodes (200) includes determining (306) a set of allowed frequencies that can be used by the ad hoc network and a corresponding index value for each of the allowed frequencies. An allowed list is created (308) and comprised of the index values (312) arranged in a deterministic order. A pointer (604) into the allowed list (600) is determined for each one of a total ofNhop frequency hops of a hopping sequence. Each pointer specifies one of the allowed frequencies (601) to be used for a corresponding one of the frequency hops. A wireless frequency hopping communication session is performed among a plurality of the nodes in the ad hoc network, using a frequency for each hop of the hopping sequence as specified by the pointers (604). The method involves dynamically assigning an updated pointer value to selected hops in the hopping sequence to specify an updated frequency to be used for that hop of the hopping sequence.
