Energy aware mobility prediction in wireless sensor networks

Abstract

Mobility of sensor nodes in wireless sensor networks significantly reduces the quality of services returned by broadcasting and routing protocols. This paper investigates the mobility factors in predicting the next location of sensor nodes to guarantee the accuracy of forwarding decisions. Based on historical location information and angular movement, nodes predict the positions of one-hop neighbors. Since this work predicts the basic mobility behaviors of the sensor nodes (i.e., speed, direction and degree of randomness), it can be also used to estimate neighborhood time, route reliability and so on. The simulation results show that the proposed work precisely estimates the next location of sensor nodes.
