Abstract
The present invention provides a system and method for evaluating the performance of a potential route before it is actually established. In a wireless network, when a trigger is received by a source node that suggests the existence of a better route, the source node sends a scouting packet along the suggested route. The scouting packet collects statistics related to the suggested route, without establishing the route while the scouting packet traverses the route. The metric for the suggested route, which is derived from the statistics collected by the scouting packet, is compared to the metric for the current route. If the metric for the suggested route is preferable to that of the current route, the suggested route is established as a new route.
