Sleepy Nodes And Sleepy Meshes – Ultra-Low-Power Mesh Routing
By Synapse Wireless Inc.

Physical nodes in a SNAP-based network communicate wirelessly using a full mesh topology. Nodes that are in direct radio range of each other will communicate directly. When nodes are not in direct radio range, intermediate nodes will automatically forward any messages to their intended destinations. This is known as "mesh routing". A SNAP-based wireless network can be used to implement a "sleepy mesh" in which all of the nodes go to sleep and wake up at the same time, extending the battery life of each node...
