Abstract: An embodiment of the invention involves a method for selecting and maintaining wireless communications for wireless mesh networks between tier-2 and tier-3 nodes. The method comprises a first operation of receiving channel information from a first wireless node operating as an access point. The channel information includes each channel number used by one or more wireless nodes that are detected by the first wireless node to be operating within a signal coverage area of the first wireless node. Then, an active scan is conducted on a frequency spectrum for wireless signals based on the channel information. Such scanning is accomplished by initially scanning frequencies of each channel number used by the one or more wireless nodes. After the scanning, a determination is made whether to (i) maintain wireless communications with the first wireless node or (ii) establish new wireless communications with a new wireless node (AP). Other embodiments are described and claimed.

Abstract: An apparatus 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.
