// Wiseroute is a simple loop-free routing algorithm that
// builds a routing tree from a central network point, designed
// for sensor networks and convergecast traffic.
//
// The sink (the device at the center of the network) broadcasts
// a route building message. Each network node that receives it
// selects the sink as parent in the routing tree, and rebroadcasts
// the route building message. This procedure maximizes the probability
// that all network nodes can join the network, and avoids loops.
// Parameter sinkAddress gives the sink network address, 
// rssiThreshold is a threshold to avoid using bad links (with too low
// RSSI values) for routing, and routeFloodsInterval should be set to
// zero for all nodes except the sink. Each routeFloodsInterval, the
// sink restarts the tree building procedure. Set it to a large value
// if you do not want the tree to be rebuilt.
