George H Flammer, Robert L Kalkwarf: Method for routing packets in a packet communication network. Metricom, Townsend and Townsend, July 3, 1990: US04939726 (244 worldwide citation)

A packet network routing method and system based on geographic coordinate identifiers is described. Each node in a network is uniquely identified by absolute geographical coordinates or by a code indicating absolute location in an external coordinate-based reference system (node coordinates), and su ...

Richard H Fox, Brett D Galloway: Method for translating internet protocol addresses to other distributed network addressing schemes. Metricom, Townsend and Townsend and Crew, June 3, 1997: US05636216 (235 worldwide citation)

In a local network connected to other networks which employ an Internet Protocol, and wherein the local network includes nodes which cannot monitor all other nodes in the local network, an Internet Protocol address of a target node in the local network is translated at a gateway node in the local ne ...

Michael W Ritter, John Bettendorff, George H Flammer III, Brett D Galloway: Method of loose source routing over disparate network types in a packet communication network. Metricom, Kenneth R Allen, Townsend and Townsend and Crew, October 29, 1996: US05570084 (224 worldwide citation)

In a packet communication system, loose source routing is employed to permit communication over networks of disparate types, including geographic and path-unaware types. No information resides on a wired access point (WAP). All of the intelligence of the system resides in Name Servers, which provide ...

George H Flammer III: Method and system for routing packets in a packet communication network using locally constructed routing tables. Metricom, Kenneth R Allen, Stephen J LeBlanc, Townsend and Townsend and Crew, January 30, 1996: US05488608 (186 worldwide citation)

In a packet communication system, wherein nodes are assigned an absolute coordinate-based address and routing decisions are made at each node without the use of directory-based routing, routing decisions made for a particular packet with an ultimate destination are stored at each node so that the ne ...

George Flammer: Method for routing packets by squelched flooding. Metricom, Townsend and Townsend, April 9, 1991: US05007052 (132 worldwide citation)

A technique is provided whereby broadcast or flooding packets received at a node are only rebroadcast if specific criteria are met. The criteria are based on a packet routing protocol wherein sequence information is maintained at each node on a link basis for each received packet and wherein receive ...
