5.4 Program flow
The program flow for both Reference Node and Blind Node are shown in Figure 2 and Figure
3. The figures are simplified.
Figure 2: Reference Node
Figure 3: Blind Node
5.5 Communication Flow
The Z-location Engine is configured to periodically query the entire network – the X,Y of all
Reference Nodes is requested and all Blind Nodes are commanded to perform a position
calculation. When a Blind Node performs a position calculation, the Over-the-Air (OTA)
message traffic can be observed as three phases: broadcast, data collection, & position
calculation and reporting.
Broadcast Phase
The Blind Node sends out a 1-hop broadcast to learn the network address of all Reference
Nodes that are within radio range. Then the Blind Node sends out a blast of several 1-hop
broadcast messages, and any Reference Node receiving such a message shall make a
running average of the RSSI of the packets received from a particular Blind Node.
Data Collecting Phase
After the broadcast phase, the Blind Node will send a 1-hop unicast message to every
Reference Node in radio range requesting the average RSSI calculated during the broadcast
blast.
Position Calculating Phase
In this phase the Blind Node calculates the position and transmits it to the Dongle.
5.6 Type definitions
Some values are given in the notation:
UINT TotalBits _ FractionalBits , this means unsigned, total TotalBits number of bits, where
FractionalBits number of bits represent the fraction part.
Example: UINT8_2 means unsigned, 8 bits with 2 fraction bits. This leaves 6 bit to the integer
part.
Both “UINT8_1”, “UINT8_2” and “UINT16_2” are used in the source code.
