Roadside network unit and method of organizing, managing and maintaining local network using local peer groups as network groups
First Claim
1. An ad-hoc wireless network system comprising;
- more than one stationary roadside network unit (RSU) each having at least one co-located antenna, said RSUs form at least one RSU group functioning as one network entity, where the same configuration parameters for a moving vehicle are used for each RSU within an RSU group;
at least one local peer group (LPG), said LPG being formed from a plurality of moving vehicles,said LPG includes;
a group header node (GH) for managing said LPG, said GH is elected from said plurality of moving vehicles;
at least one group node (GN) designated from the remaining moving vehicles of said plurality of moving vehicles,each of said plurality of moving vehicles is configured to determine an identity of the RSU group based on beacon, and is further configured to determine if an RSU is of the same group, use the same configuration parameters if said group is determined to be the same,each of said plurality of moving vehicles, whether said GH or said at least one GN, communicates with other of said plurality of moving vehicles using routing paths created based upon a first control packet broadcast from said GH and a second control packet broadcast from each of said at least one GN, each of said moving vehicles communicates with said at least one RSU group using a routing path created based upon a beacon broadcast by said at least one RSU group and a reply signal from each of said plurality of moving vehicles.

Abstract
An ad-hoc wireless network with a roadside network unit (RSU) and a local peer group (LPG). The LPG is formed from a plurality of moving vehicles. The LPG includes a group header node (GH) for managing the LPG. The GH is elected from one of the moving vehicles. The LPG further includes group nodes (GN) designated from the remaining moving vehicles in a given area. Each of the moving vehicles, whether the GH or the GN, communicates with other using routing paths created based upon a first control packet broadcast from the GH and a second control packet broadcast from each of the GN. Each moving vehicle communicates with the RSU using a routing paths created based upon a beacon broadcast by the RSU and a reply signal from each of the moving vehicles. The RSU can also be a member of the LPG and act as GN or GH.

27. A method for managing an ad-hoc wireless network comprising steps of:
-
forming, from more than one stationary roadside network unit (RSU) each having at least one co-located antenna, at least one RSU group operable to function as one network entity, where the same configuration parameters for a moving vehicle are used for each RSU within an RSU group; forming at least one local peer group (LPG) from a plurality of moving vehicles, electing a group header node (GH) for managing said LPG, said GH is elected from said plurality of moving vehicles; designating at least one group node (GN) from the remaining moving vehicles of said plurality of moving vehicles; each of said plurality of moving vehicles is configured to determine an identity of the RSU group based on beacon, and is further configured to determine if an RSU is of the same group, use the same configuration parameters if said group is determined to be the same, communicating between each of said plurality of moving vehicles, whether said GH or said at least one GN, using routing paths created based upon a first control packet broadcast from said GH and a second control packet broadcast from each of said at least one GN; and communicating between each of said moving vehicles and said at least one RSU group using a routing path created based upon a beacon broadcast by said at least one RSU group and a reply signal from each of said plurality of moving vehicles. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
