Wireless mesh network
First Claim
1. A wireless mesh network configured to reduce negative effects related to density of said wireless mesh network, said wireless mesh network comprising:
- a plurality of nodes, wherein each of said plurality of nodes is configured to receive a message within a receive range having an adjustable size and selectively rebroadcasts said received message;
wherein said size of said receive range of each of said plurality of nodes receive range size is selected based on receive sensitivity, wherein said receive sensitivity of at least a first subset of said plurality of nodes is selected such that said adjustable size of said receive range at which a node receives a message is reduced; and
wherein said first subset of said plurality of nodes with reduced receive range do not rebroadcast received messages, and said plurality of nodes includes a second subset of said plurality of nodes without reduced receive range that selectively rebroadcast said received messages.

Abstract
A wireless mesh network where a portion of the nodes have reduced receive sensitivity. The negative effects of the density of the wireless mesh network, such as interference, are reduced when fewer nodes receive messages to rebroadcast. In an alternative embodiment, some of the nodes of the mesh network are configured to not rebroadcast even if they receive a message. A method for configuring a dense mesh network is also provided. As many nodes as possible are discovered and registered in the network. Node characteristics of those nodes are adjusted to reduce or eliminate the negative effects of the dense mesh network so that additional nodes may be discovered and registered.

6. A method for configuring a dense wireless mesh network including a plurality of rebroadcasting nodes to reduce negative effects related to density in said dense wireless mesh network, said method comprising:
-
discovering a first subset of the plurality of rebroadcasting nodes in the dense wireless mesh network; registering the first subset of the plurality of rebroadcasting nodes; and adjusting receive sensitivity of at least one of the nodes of the first subset of said plurality of rebroadcasting nodes to reduce negative effects related to density in said dense wireless mesh network, wherein reducing receive sensitivity of at least one of the nodes of the first subset of said plurality of rebroadcasting nodes reduces messages received by said first subset of said plurality of rebroadcasting nodes, wherein reducing messages received by said first subset of said plurality of rebroadcasting nodes reduces the messages rebroadcast by the first subset of said plurality of rebroadcasting nodes; wherein said adjusting allows a second subset of said plurality of nodes to be discovered and registered. - View Dependent Claims (7, 8, 9, 10, 11, 12)
