Abstract

In mobile ad hoc networks, nodes are dynamically changing their locations. The QoS information used for routing by traditional QoS routing protocols becomes obsolete due to node mobility. To overcome this problem, a predictive QoS routing scheme is needed. In this paper, we present a location-delay prediction scheme, based on a location-resource update protocol, which assists a QoS routing protocol. Our location updates also contain resource information pertaining to the node sending the update. This resource information for all nodes in the network and the location prediction mechanism are together used in the QoS routing decisions. Our simulation results show that, with our approach, we can predict the location at a given instant in the future with a high degree of accuracy.
