Method Summary

boolean	areNeighbours(java.net.InetAddress addr1, java.net.InetAddress addr2) Checks if the two nodes are neighbours (are in radio range) in the current network topology
java.net.InetAddress	getEmuNodeAddress(int nodeId) Returns a new InetAddress for an existing node in the simulation
static VirtualNetworkInformation	getInstance()
java.util.List<java.net.InetAddress>	getNeighbours(java.net.InetAddress addr) Returns a list with all the neighbours of the given address If there are no neighbours, means that the node is isolated and is not currently connected to the others
int	getNetworkSize() Returns the total number of nodes in the network
java.lang.String	getStringGraph()
boolean	performTopologyChangesUntilSecond(int second)
