Header

Each k7 starts with a one-line header. The header is the json dump of a dict. The header contains the dataset meta data. Ex:

{"location": "grenoble", "tx_length": 100, "start_date": "2017-06-20 16:22:15", "stop_date": "2017-06-21 10:29:29", "node_count": 50, "channels": [11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26], "interframe_duration": 10}

Data

datetime	src	dst	channel	mean_rssi	pdr	tx_count
iso8601 string	int	int	int	float	float (0-1)	int

Standard example:

datetime	src	dst	channel	mean_rssi	pdr	tx_count
2017-12-19 21:35:41	0	1	11	-74.5	1.0	100

The source or destination can be empty (i.e when measured on all the neighbors of the src):

datetime	src	dst	channel	mean_rssi	pdr	tx_count
2017-12-19 21:35:41			11	-74.5	0.7	100

Unknown channel:

datetime	src	dst	channel	mean_rssi	pdr	tx_count
2017-12-19 21:35:41	1	2		-79.5	1.0	100

When the channel value is empty, it means that the channel is unknown for that measurement.
