JenNet wireless network protocol stack
This`stack`is`used`to`manage`the`following:`network`formation,`
the`execution`of`join`and`repair`functions,`and`packet`
transmission`between`nodes.
`
`
`Based`on`IEEE`802.15.4`MAC`and`PHY`and`6LoWPAN`
IPv6`IETF`standard,`backwards`compatible`with`IPv4
`
`
`Highly`robust,`easily`scalable,`mesh-under`star,`tree,`and`
linear`network`topology`proven`at`over`500`nodes
`
`
`Gateway`and`non-gateway`options`for`connecting`
`o`the`internet`(via`low`cost`ethernet-15.4`IP-bridge)`
`or`standalone`operation`
`
`
`Automatic`route`formation`and`self-repair`to`prevent`
single-points-of`failure`and`network`re-shaping`
functionality`to`reduce`network`‘depth’`and`latencies
`
`
IP`/`ICMP`/`UDP`Internet`Protocol`stack
`
`
`Easy-to-use`MIB-`and`SNMP-model`based`SNAP`application`
API`tuned`for`extensible`sensing/control`
`
`
`Provides`real`end-to-end`communication`between`
`nodes,`eliminating`all`issues`associated`with`intermediate`
expensive`and`power-hungry`Home`Automation`
gateways`like`increased`latencies,`security``issues,`
limited`feature`visibility`&`expandability`and`state`integrity
`
`
`Highly`secure`authentication`&`device`joining`and`secure`
communication`with`128-bit`AES`encryption,`simple`
commissioning`of`standalone`networks`with`a`remote`
with`reduced`radio`performance`during`key`exchange`
`
`
`Future`proof`with`“Over-the-Network”`download`
functionality``for`firmware`updates
`
`
Sleeping`end-devices`for`extended`battery`life
`
`
Co-existence`with`Bluetooth`and`Wi-Fi
`
`
`Low-power`option`for`applications`requiring`low`standby`
power`
`
`
`Low`cost`of`ownership:`small`memory`footprint`~`85`kB,`low`
`development`cost,`low`complexity,`license-free,`compliance-free
