Abstract: Spread-spectrum technology, either direct sequence or frequency hopping, or a combination of the two, is used for transmitting audio signals one way and control signals two ways over an RF channel(s) to reduce interference with/from other RF transmissions and enabling use of multiple such systems in close proximity without requiring pre-selection of transmission frequencies. Alternatively, multiple channels with appended access codes may be used, wherein interference or loss of clear signal results in automatic switching to another channel. The control signals accompany the transmitted audio signal at some time in the transmission interval, or previous to the beginning of the transmission interval, and constitute a coded control message allowing a unique connection. In some cases the encoding keys may only occur at the beginning of the desired message, while in other cases the two-way control signals may continue throughout the interval of the message link.

Abstract: A wireless sensor network having mobile sensors (64, 65) is provided with a fixed grid of potential sinks, one of which (70) is currently active as the network sink. To re-position the sink, the current sink (70) finds candidate sinks (72-79) among the nearby potential sinks and requests from them a measure of their suitability to act as the future sink. To do this, the candidate sinks (72-79) obtain data and/or signals from the sensors (64, 65) within their range to estimate a total throughput which they would expect to achieve if acting as the sink. In one embodiment the desired data rates of the sensors (64, 65) are also taken into account. The current sink (70) then transfers the role of active sink to the most suitable candidate (e.g. 76) thus found.
