An apparatus, system and method for a multi-tier wireless home mesh network is described. The method may include formation of an infrastructure-less wireless home mesh networking environment comprising a collection of nodes that operate as a decentralized, ad hoc wireless network with multiple sub-networks or tiers that are responsible for different functions within the network. Each node of the multi-tier network is configured to forward data to other nodes and is assigned to a particular tier based on the node's performance capabilities. A further embodiment includes identification of a wireless home mesh network. Once identified, one or more proprietary messages may be exchanged in a secure manner to establish connections with a home electronics device as either a mobile node or a stationary node of the home network. A home electronics device may wirelessly communicate to route data within one or more nodes of the wireless home mesh network. Other embodiments are described and claimed.

The method of claim 1, wherein the tier type is one of (i) a first tier node being a gateway node that establishes and controls access to an external network, (ii) a second tier node being a stationary wireless node that interconnects a plurality of stationary wireless nodes, and (iii) a third tier node being one of a plurality of mobile wireless nodes that are linked to the second tier node. 3. The method of claim 2, wherein the WHMN includes at least one first tier node and one second tier node. 4. The method of claim 3, wherein the first node is a third tier node and the second node being a second tier node. 5. The method of claim 4, further comprising the first node: establishing a wireless link between the first node with the second node to join the WHMN as a mobile node;sharing services and content with the second node; andaccessing a wired network via the wireless link with the second node. 6. The method of claim 2, further comprising: wirelessly interconnecting one or more second tier nodes to form a backhaul of the WHMN; andwirelessly exchanging high definition (HD) video content between the second tier nodes. 7. The method of claim 1, further comprising: scanning one or more channels to detect the presence of one or more available wireless networks. 8. The method of claim 1, wherein connecting to the first wireless ad hoc network includes: sending, by the first node, a connection request message including an encrypted phrase to the second node; andreceiving, by the first node, a connection confirmation message from the second node if the connection request message is validated by the second node. 9. The method of claim 1, wherein the WHMN discovery request is proprietary and is recognized by WHMN-enabled nodes. 10. The method of claim 1, further comprising: initiating, by the first node, a WHMN if the WHMN discovery response is not received by the first node. 11. An apparatus comprising: means for establishing a wireless communication interface;means for establishing a wireless home mesh network (WHMN);means for broadcasting a WHMN discovery request to discover at least one WHMN, the WHMN discovery request including at least a tier type of the apparatus and a first challenge text, the first challenge text including a secret key combined with an extended service set identification (ESSID); andmeans for sending a WHMN discovery response including at least the tier type of the apparatus and a second challenge text, the second challenge text being derived from at least a public key of the apparatus and a MAC address of the apparatus. 12. The apparatus of claim 11, wherein the means for broadcasting the WHMN discovery request to display a list of one or more detected WHMN and to join a selected WHMN. 13. The apparatus of claim 11, wherein the tier type is one of (i) a first tier node being a gateway node that establishes and controls access to an external network, (ii) a second tier node being a stationary wireless node that interconnects a plurality of stationary wireless nodes, and (iii) a third tier node being one of a plurality of mobile wireless nodes that are linked to the second tier node, andwherein the WHMN comprises at least one first tier node and a second tier node. 14. The apparatus of claim 13, wherein the WHMN discovery request is a request to join an identified WHMN as a second tier node or a third tier node, wherein the second and third tier nodes of the identified WHMN wirelessly communicate to share features and content within the identified WHMN. 15. A system comprising: a first tier node being a wireless gateway coupled to a wired network to operate as a gateway node of a wireless home mesh network (WHMN);a second tier node being a stationary wireless device that communicates with the first tier node, interconnects a plurality of stationary wireless nodes, and operates as the stationary wireless node of the WHMN;a third tier node being a mobile wireless device to communicate with the second tier node to join the WHMN as a mobile wireless node of the WHMN, wherein the stationary node and the mobile node of the WHMN wirelessly communicate to share content and network services,wherein joining the WHMN includes broadcasting, by the third tier node, a WHMN discovery request, the WHMN discovery request including at least a first challenge text, the first challenge text including a secret key combined with an extended service set identification (ESSID),if the first challenge text is verified by the second tier node to be an expected value, receiving the WHMN discovery response by the first tier node, the WHMN discovery response including at least a second challenge text, the second challenge text being derived from at least a public key of the second tier node and a MAC address of the second tier node, andconnecting to the WHMN by the first node using parameters included in the WHMN discovery response. 16.
