Functions

func SelectDownlinkGateway

func SelectDownlinkGateway(minSNRMargin float64, rxDR int, rxInfo []storage.DeviceGatewayRXInfo) (storage.DeviceGatewayRXInfo, error)

SelectDownlinkGateway returns, given a slice of DeviceGatewayRXInfo elements the gateway (as a DeviceGatewayRXInfo) to use for downlink. In the current implementation it will sort the given slice based on SNR / RSSI, and return:

• A random item from the elements with an SNR > minSNR
• The first item of the sorted slice (failing the above)

Types

type BySignal

type BySignal []storage.DeviceGatewayRXInfo

BySignal implements sort.Interface for []gw.UplinkRXInfo based on signal strength.

func (BySignal) Len

func (s BySignal) Len() int

Len returns the number of elements.

func (BySignal) Less

func (s BySignal) Less(i, j int) bool

Less returns if i is greater than j (reverse sorting).

func (BySignal) Swap

func (s BySignal) Swap(i, j int)

Swap swaps i and j.
