Abstract:

A mesh network is initiated by using multiple frequency bands for establishing communication between mesh nodes. In one aspect, a higher or lower frequency communication link may be established depending on the range between two mesh nodes. As the mesh network increases and decreases in density, and range and communication aspects change, a communication link may be change between the higher and lower frequency bands as necessary.

Abstract:

A logical distributed server is generated for managing (Internet Protocol (IP) address allocation for an ad-hoc, self-forming peer-to-peer (P2P) network. The logical distributed server is generated according to messaging scheme where nodes on the P2P network allocate addresses for themselves and for clients connected to them. Each node implements a server that listens on the incoming client connections. Each node maintains data structures that represent the current state of an address database. Routing requests are fielded by the nodes from the clients and the messaging scheme is used to inform other nodes of its action so a consistent address space is maintained between all the nodes on the P2P network.
