NEURAL NETWORK-BASED MOBILITY MANAGEMENT FOR HEALING MOBILE AD HOC RADIO NETWORKS
First Claim
1. A method of managing an ad hoc communications network, said method comprising the steps of:
- a) locating a plurality of nodes within a coverage area;
b) selecting at least one of said plurality of nodes within at least one group said plurality of nodes as a healing node, each of said healing node being relocatable within a corresponding said group;
c) locating each said healing node at a location;
d) training said healing nodes to selectively reconnect to at least one other said group whenever a connection to other said nodes of at least one other said group is lost; and
e) relocating each said healing node at said location.

Abstract
A self healing ad hoc communications network and method of training for and healing the network. The network includes wireless devices or nodes that include a neural network element and the ad hoc network operates as a neural network. Some of the nodes are designated as healing nodes that are identified during network training and are strategically located in the network coverage area. Whenever one group of nodes loses connection with another a healing node may reposition itself to reconnect the two groups. Thus, the network can maintain connectivity without constraining node movement.

13. A method of training healing nodes in an ad hoc communications network, said method comprising the steps of:
-
a) selecting a node location from a plurality of node locations in an ad hoc communications network; b) identifying a winner node as being closest of the remaining ones of said plurality of node locations; c) determining whether a node at the selected said node location is within a selected maximum distance from said winner node; and d) determining whether said ad hoc communications network is connected. - View Dependent Claims (14, 15, 16, 17)

18. A method of managing nodes in an ad hoc communications network, said method comprising the steps of:
-
a) training communications nodes off-line for a selected coverage area, said ad hoc communications network including a plurality of mobile nodes initially located at selected locations in said coverage area and grouped into a plurality of groups, at least one of said plurality of nodes being selected as healing nodes within each group of said plurality of nodes, each of said healing nodes being relocatable within a corresponding said group; b) deploying the trained said nodes in an ad hoc communications network; c) monitoring, within each said group, connection to at least one other said group; and
upon loss of connection,d) relocating a corresponding said healing node to reconnect each said group to the at least one other said group. - View Dependent Claims (19, 20, 21, 22, 23)

24. A node trainable as a healing node for use in an ad hoc communications network comprising:
-
off line training means for receiving off-line training for a selected coverage area in an ad hoc communications network of a plurality of mobile nodes grouped into a plurality of groups; transportation means for locating said healing node to a preselected location, responsive to said training; means for monitoring connection of a group of ad hoc communications network nodes to at least one other group; and means for determining a location to reconnect said group to said at least other group, responsive to said training, said transportation means further being for relocating said healing node to the reconnect said location. - View Dependent Claims (25, 26)
