WACNet: wireless ad-hoc community network

Ad-hoc networks utilizing wireless technology have been considered as a means of communications among portable user terminals that temporarily meet, where distance and time come close yet easy connection to a network infrastructure is not possible. We advance this concept of ad-hoc networks and propose a wireless ad-hoc community network (WACNet) in order to use such networks in ad-hoc communities, which are formed between an unspecified number of people temporarily assembled with a common purpose. We introduce the basic concept and features of the WACNet. The key technologies achieving the WACNet are also presented, including routing schemes, SDMA, user terminals, microwave signal processing concepts and electronically steerable passive array radiator (ESPAR) antennas
