Abstract: The present invention relates to a system for allocating unused radio frequency spectrum channels with the TV White space frequency band. A spectrum manager is arranged to allocate available white space channels to requesting wireless access point devices. When more than two devices request channels, the spectrum manager determines any mutual interference that may be caused by those devices and allocates channels so as to minimise mutual interference. Where there are more requesting devices than available channels, the spectrum manager is arranged to auction the channels until the demand is equal to the available channels.

Abstract: Data collected by sensors (10, 30) is transmitted to data collection points (31, 61) over a network using an epidemic protocol in which data received by a relay (3) is forwarded to a randomly-selected group of further relays (4, 5, 6) unless the same data has been previously received by the relay (3) or the data is time-expired. Data received by a relay (3) from different sources (1, 2, 30) in the same time-frame is aggregated using a Bloom filter process so that in each time frame only a single Bloom filter message is transmitted by each relay.

Abstract: A multicast system is described in which a mechanism for suppressing feedback involves the receivers using an optimized timer function for selecting a backoff delay time before sending feedback, and canceling their feedback if in the meantime they detect that another receiver has sent a duplicate feedback message. The timer function is optimised, taking into account both the expected number of feedback messages and the extra latency which is introduced by the feedback mechanism, by minimizing an objective function expressed in terms of both these two aspects.
