When no effort is made to put the sensor as close as possible to the path ( sensors are spread totally randomly), the uniform distribution is obtained.
Within the TK3.1 software, a number of calculations and standard corrections for open-path sensors to produce quality controlled (QC) and quality assured (QA) data were performed after the raw data such as air temperature, water vapour, CO2 and the three components of the wind velocity (u, v and w) had been retrieved from the CR3000 and CR1000 data loggers.
Our students learn to develop integrated manufacturing cells and machines that contain automated material handling systems, machining, tool path planning, sensor systems, quality control, and error handling.
In this configuration, source and destination nodes can be separated by long distances; thanks to a dedicated path of sensor nodes forming parent child links.
However, those systems have high initial facility cost and are difficult to maintain according to changes of environment, and it can drive only the designated path by sensors which are installed on.
(b) Considering both, the multi-path and sensor synchronization errors.
Moreover, some least power paths between sensor nodes are unfortunately lost.
Paths from sensor nodes nearer to the sink are added earlier gradually.
In WSNs, routing protocols discover and maintain paths between sensor nodes and the base station.
According to the characteristic of Wiener index, the MWST can provide efficient transmission paths for sensor nodes.
