What is Mote in Wireless Sensor Network?
SmartMesh IP Motes
SmartMesh IP Motes are the wireless nodes in a SmartMesh IP network. They connect to sensors/actuators and route data from other motes, yet remain low power.
Each mote can both send and receive messages (supports bidirectional data). Each mote may have a different data reporting rate and the network manager will automatically coordinate individual pair-wise communications to efficiently route the traffic.
Each mote may have a different power supply capability (e.g. line-, battery-, or energy- harvested power). The network manager will load balance traffic accordingly to extend time until the network's first battery replacement.
SmartMesh IP networking software is compiled and fully tested. Motes have an on-board ARM Cortex-M3 processor that supports customer application software using the SmartMesh IP On-Chip Software Developer Kit. Alternatively, a mote may be controlled by an external microprocessor through its serial API interface.
SmartMesh IP Network Managers
SmartMesh IP network managers perform two major functions for the mesh network. First they serve as an access point mote, connecting the wireless mesh to customer host applications. Second, network managers run sophisticated network management algorithms to maintain performance of the network
SmartMesh IP network managers come in two versions: EManager (supports up to 100 motes) and VManager ( supports thousands of motes).
SmartMesh IP EManager
An EManager, or embedded manager, runs as a Manager-on-Chip™ where both the access point function and the network management algorithms run on board the SmartMesh IP 802.15.4 hardware (e.g. LTC5800-IPM)
EManagers support up to 100 motes in the network and are ideal for low power gateway operation.
SmartMesh IP VManager
VManager is a software-based manager and separate Access Point Motes that enables:
- Large Networks – thousands of nodes
- Increased Bandwidth through Multiple Access Points
- Hot Failover Gateway Redundancy
VManager software runs on an x86 virtual machine (VM), which can be installed on a variety of hardware platforms, from cloud servers down to low power embedded x86-based processors. The VManager software is delivered from Linear Technology as a pre-compiled and tested VM application that may run on VMWare, or Oracle VirtualBox VMs.
One or more Access Point Motes (AP Motes) connect the SmartMesh IP network to the VManager software. An AP Mote is the combination of AP Mote software running on SmartMesh IP 802.15.4 hardware (e.g. LTC5800-IPM)
Hardware Form Factors
SmartMesh IP 802.15.4 hardware is available in chip package, or as pre-RF-certified printed circuit board assemblies (PCBA). The 802.15.4 hardware's network behavior is defined by the type of SmartMesh IP software loaded onto the hardware (i.e. mote software, network manager software, or access point mote software).
