Meshnet

MeshNet

This is a project to define and potentially build a hardware/software solution for a web base network of sensor and control modules which will be cost effective to build and market.

Processors

Communications

Initially we are looking into using ZigBee ZigBee.orgas the communcations basis for the platform.

Architecture

Initial architecture based around a central/interface node which is connected to the LAN via either hardwired ethernet or wireless ethernet (802.11). This node will identify and connect to as many remote sensor nodes as can identified directly. Using the zigbee mesh network topology identify additional nodes which communications can be relayed via the directly connected nodes.

The central node does not provide any sensor data directly, just a web based interface for controlling the network of devices.

The sensor nodes can provide a single function, as simple as a temp sensor or as complicated as a web cam. The current list of possible sensor nodes is:

* temp sensor
* humidity sensor
* gpio sensor (could be connected to motion sensor)
* 1-wire devices (1-wire based weather station)
* web camera
* rs232 interface
* usb host interface
