Abstract

A method and system for dynamic information exchange on mesh network devices. A mesh network device with integrated features creates an N-way mesh network with a full mesh network topology or a partial mesh network or an ad-hoc network topology. The mesh network device is able to dynamically exchange information with other mesh network devices using stored profiles (e.g., personal data, advertisements, instant coupons, location-aware information, etc.) via a mesh network or partial mesh network or ad-hoc network.

receiving a first set of profile information on a first mesh network device, wherein the first mesh network device includes an ultra wideband wireless transceiver and a mesh network protocol adapter with Complementary Code Keying (CCK), Differential Quaternary Phase Shift Keying (DQPSK) or Orthogonal Frequency Division Multiplexing (OFDM) encoders;

sending periodically a wireless signal from the first network device to a mesh network including a plurality of other mesh network devices including other sets of profile information, wherein one or more of the plurality of other mesh network devices include an ultra wideband wireless transceiver and a mesh network protocol adapter with Complementary Code Keying (CCK), Differential Quaternary Phase Shift Keying (DQPSK) or Orthogonal Frequency Division Multiplexing (OFDM) encoders and;

receiving one or more wireless signals from the plurality other mesh network devices on the mesh network, wherein the one or more wireless signals include the other sets of profile information stored on the plurality of other mesh network devices; and

determining from the received one or more wireless signals whether any items in first set of profile information on the first network device match any items in the other sets of profile information stored on the plurality of other mesh network devices, and if so,

exchanging a set of data between the first network device and any of the one or more other mesh network devices for which any profile information matches via the mesh network.

2. The method of claim 1 further comprising a non-transitory computer readable medium having stored therein instructions for causing one or more processors to execute the steps of the method.

3. The method of claim 1 wherein the first set of profile information includes an e-mail address, an Internet Protocol (IP) address, a hardware address, a universal resource locator (URL), a name, a street address, an telephone number, an instant message identifier, a text message identifier, a encryption key, a digital signature, a secure message digest, a security identifier, a mesh network identifier, public or emergency notices or location specific information including location-aware information.

4. The method claim 1 wherein the step of sending periodically a wireless signal includes sending an IEEE 802.15.4 (ZigBee) wireless protocol signal.
