1. A method for establishing and maintaining a mobile ad-hoc network between a plurality of moving wireless devices, said method comprising:

  • operating a first device of said plurality of moving wireless devices as a first equivalent cell header (ECH), said ECH having a radio coverage range;

    establishing a first equivalent cell (EC) for said first ECH, said first EC being formed centralized within an area of a radio coverage range of said first ECH and dimensioned to occupy a portion of said area, said EC being managed by said ECH;

    broadcasting ECH information (ECH_HELLO) message from said first ECH, said ECH_HELLO message announcing that said one device of said plurality of moving wireless devices is the first ECH, said ECH_HELLO message broadcasts occurring at randomly determined fixed intervals;

    receiving, by said first wireless device, at least second ECH_HELLO messages broadcast from at least a second moving wireless device operating as at least a second ECH;

    creating a linked equivalent cell network between said first and second ECHs, if said second ECH is the only other ECH_HELLO message received or if two or more received ECH_HELLO messages belong to unlinked ECHs; and

    operating said first device as a regular node in said linked equivalent cell network, if two or more received ECH_HELLO messages belong to a unified chain of linked ECHs, said regular node being part of said linked equivalent cell network, and said regular nodes having restricted communication privileges in comparison to an ECH.
