Predictive location-based QoS routing in mobile ad hoc networks
نویسندگان
چکیده
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.

Improving Quality of Service Routing in Mobile Ad Hoc Networks Using OLSR
Mobile ad hoc networks (MANET) are constructed by mobile nodes without access point. Since MANET has certain constraints, including power shortages, an unstable wireless environment and node mobility, more power-efficient and reliable routing protocols are needed. The OLSR protocol is an optimization of the classical link state algorithm. OLSR introduces an interesting concept, the multipoint r...
