All Implemented Interfaces:

java.lang.Runnable, java.io.Serializable

public class MicroPingClient

extends java.lang.Thread

implements java.io.Serializable

This class sends ping requests at certain intervals. This class operates in one of two modes:
1) MobilityManager: Pings all nodes that are 'connected' to this MM,
2) MobilityAgent: Pings its own Director node. The interval between pings is determined dynamically, where loss of connetcion will cut the current interval in half, and a online connection of more than 10*initial interval will increase the current interval by the initial interval.
