Tinymesh™ Application and Protocol Stack
The Tinymesh™ Multi-hop Wireless Mesh Network Protocol Stack is a unique set of multi-hop wireless
mesh network protocols that enable devices to send messages or transfer data to and from each other.
The embedded Application Layer contains an advanced set of configurable I/O handling mechanisms
that enable Tinymesh™ devices to be implemented in most application circuits without need for an
external MCU.
The Tinymesh™ Stack requires no external processor for establishing and maintaining the optimum
network routing path at all times.
Internet applications may connect to Tinymesh™ Wireless Mesh Network through the equally
uncomplicated Tinymesh™ Cloud Services.
Tinymesh™ Multi-hop Wireless Mesh Networks may consist of large numbers of Tinymesh™ enabled
devices or nodes where a node is one out of three types as described below. The wireless traffic
between the Tinymesh™ enabled devices follows a tree-type topology, where data transfer is up or
down in the tree structure.
A Tinymesh™ Multi-hop Wireless Mesh Network in its simplest form consists of a single Gateway and a
Router. End Devices will not perform packet routing and must connect to a Router or directly to a
Gateway. A network may be comprised of thousands of Tinymesh™ enabled devices. There may be
several Gateway devices within a network, for redundancy and automatic workload sharing.
The network addressing structure uses four-byte addressing, for a total of 4.3 billion possible unique
devices per network. The network tree structure may have a total depth 255 hops.
Tinymesh™ Devices
Any Tinymesh™ enabled device may be configured to function as Gateway, a Router or as an End
Device. Single byte configuration commands will set all relevant configuration parameters when
changing operating mode.
Gateway Device
A Tinymesh™ network must have at least one Gateway Device. The Gateway Device initiates the
network formation, and is required to keep the network alive. Gateway Devices provide the connection
between the Tinymesh™ Routers and End Devices, and an external host processor, or to a local- or
wide area network, such as the Internet.
The Tinymesh™ stack supports implementations with multiple Gateways, where additional Gateway
devices provide redundancy and data traffic load sharing.
Gateway devices support full Input / Output control capabilities, similar to Routers and End Devices.
Router Device
Router Devices are full-functioning devices with serial data UART and Input / Output capabilities. Router
Devices provide the communication path between individual Router- or End-devices, and the network
