Techniques for sending data in a packet-switched communications network include determining multiple subsets of adjacent network nodes of the network. The adjacent network nodes communicate without intervening network nodes with a particular network node through an interface on the particular network node. Each subset includes multiple adjacent network nodes. Subset definition data is sent through the interface. The subset definition data indicates which adjacent network nodes belong to which subset. Data for fewer than all adjacent network nodes in all subsets are sent by including, in a multicast data packet sent over the interface with a multicast destination address, subset identifier data that indicates a particular subset. When such data is received by a node, it is discarded unless the subset identifier matches the receiving node's subset identifier. Among other effects, this allows routing messages to be more efficiently sent to better performing neighboring network nodes.

The present invention increases the aperture size of a microphone array by introducing a diffracting structure into the interior of a microphone array. The diffracting structure within the array modifies both the amplitude and phase of the acoustic signal reaching the microphones. The diffracting structure increases acoustic shadowing along with the signal's travel time around the structure. The diffracting structure in the array effectively increases the aperture size of the array and thereby increases the directivity of the array. Constructing the surface of the diffracting structure such that surface waves can form over the surface further increases the travel time and modifies the amplitude of the acoustical signal thereby allowing a larger effective aperture for the array.

Techniques for sending routing data include sending first routing data in a first multicast packet to a number N of adjacent nodes. It is determined whether different routing data is ready to be sent in a different multicast packet. If so, then a number M of adjacent nodes from which acknowledgment messages have been received, and whether M exceeds a threshold, is determined. If so, then a Conditional-Receive (CR) method is invoked in which a multicast message is sent which identifies each of a number L=N−M of laggard adjacent nodes. The laggard adjacent nodes are thus notified to ignore the different multicast packet. If it is determined that M does not exceed the threshold, then additional acknowledgement messages are received while waiting until M does exceed the threshold before the CR method is invoked. The threshold is greater than or equal to 1.
