Interface LocalAir

All Known Implementing Classes:

LocalAirImpl

public interface LocalAir

local air each device has a local view on the global air. It sees different packets and transmission power.

Method Summary

void	addNeighbor(LocalAir r) add a new node the air
void	addPacket(Radio.RadioPacket p, double pow, Radio sender) add packet to be received, called by transmitting nodes
java.util.Iterator	getNeighbors() get list of nodes around
Position	getPosition() get the position of this node
Radio	getRadio()
void	removeNeighbor(LocalAir r) remove node from the air
int	sampleRSSI(long cycles) measure the signal strength around here
