Abstract

Communication nodes for use with a wireless ad-hoc communication network are disclosed. In an embodiment of the present invention, the communication node comprises a transducer, which generates a signal in response to an external signal. The ad-hoc network communication is supported in part by static communication nodes, which defined an organized infrastructure network in order to achieve the various functions of the transducers. In another embodiment, the communication node for use with a wireless ad-hoc network does not include a transducer. Such communication nodes are preferred for use with a less structured network with virtually no infrastructure and allow for being used with expanding and contracting networks. Mobile communication nodes mostly support the propagation of signals. However, pseudo-static or static communication nodes are also used in wireless communication ad-hoc networks.
