A routing method for supporting ad-hoc mobile communications within a radio communications network. The network comprises a plurality of mobile hosts including a source mobile host and a destination mobile host, and a plurality of radio communications links connecting together with mobile hosts. The method comprises measuring the stability of the communications links between neighbouring mobile hosts using an associativity based characteristic and selecting a communications route through the network from the source mobile host to the destination mobile host based on the stability of the communications links. The associativity characteristic is measured by each mobile host periodically transmitting and receiving identifier beacons (ticks) and updating the status of its corresponding links. The greater the number of ticks associated with a given link, the greater its stability. Use of the associativity characteristic enables the routing method to deal efficiently with mobile host migrations throughout the network.
A routing method for supporting ad-hoc mobile communications within a communications network, the network comprising a plurality of mobile hosts including a source mobile host and a destination mobile host and a plurality of wireless communication links connecting together said mobile hosts, said method comprising:
In a base-station oriented wireless local area network comprising a plurality of mobile hosts, a wired network, a static host and a plurality of base stations, the static host and said base stations each being connected to the wired network, said base stations each having an associated wireless communications area within which the base station can communicate with one or more mobile hosts, and wherein said mobile host having established a first communications link with the static host via a first base station, migrates into a second wireless communications area of a second base station which is too heavily used to support a second communications link of the same bandwidth as the first, a method of re-establishing communications between said migrating mobile host and said static host, said method comprising:
