Abstract: An apparatus and method for predicting mobility based on relative mobile characteristics are disclosed herein. The method of predicting mobility based on relative mobile characteristics includes detecting, by each of a plurality of sensor nodes of a sensor network including the plurality of sensor nodes, a change in relative location with respect to an observed node; recording, by the each of the plurality of sensor nodes, information about the detected change in relative location; generating, by the each of the plurality of sensor nodes, a mathematical model for a possibility of approach of the observed node with respect to the each of the plurality of sensor nodes using the recorded relative location change information; and predicting probabilistically, by the each of the plurality of sensor nodes, whether the observed node will approach the each of the plurality of sensor nodes using the mathematical model.

Abstract: The present invention relates to methods and apparatuses for establishing a routing path in a multi-hop network. The methods comprises (a) transmitting a notification message associated with communication problem to neighboring nodes, (b) deriving approaching characteristics of a communication problem-causing element from the notification message, and (c) establishing a routing path based on the approaching characteristics of the communication problem-causing element. With the methods and apparatuses, it is possible to determine a path that is expected to experience a communication problem based on the approaching characteristics of a communication problem-causing element and to adaptively establish a reliable routing path.
