Internally Developed Wireless Mesh

There are many wireless protocols in the market, e.g. Bluetooth, WiFi, ZigBee, etc. These protocols are designed for mass consumer market, and often not suitable for remotely deployed sensors that have power supply constraints. In fact, power supply is the primary design metric for many remote wireless sensors.
​
Traffic characteristics for security & environmental monitoring applications, 
  • Short-burst/sporadic data
  • Low bandwidth throughput 
  • Flexibility of mesh networking for unplanned large scale deployment; and to achieve desired radio range with less power consumption.
Disclaimer: this is the earlier implementation. Contact us for the updated protocol!

Characteristics

  • Ad-hoc data-driven route discovery protocol with self healing capability
  • Optimal route is selected at each node, based on cost function. This cost is a function of link quality and sensor’s health status.
  • Route discovery/self-healing are integrated into the data transmission; and with minimal overhead.
  • Zero route maintenance.
  • Once route is established, data communication are acknowledged / lossless.
  • Guaranteed low network overhead.
  • Short messages may be combined to reduce overhead and possible collisions.
  • Universal node type allows random deployment/dispersion.
  • No Operating System (OS) which imposes difficulty and reduces the flexibility during protocol implementation; but it reduces power consumption requirement significantly as well. Commercial mesh could be running on OS (e.g. TinyOS, Contiki, MANTIS, Btnut etc) and may be designed for broad bandwidth radios.
  • Integrate seamlessly with in-house developed radio hardware and wireless sensors.
  • Note: this wireless mesh will be opened at application layer, and industrial partners may interface to this radio via standard serial command.
