A system for efficient routing in a multiple hop wireless communication network comprising a plurality of network nodes is presented. The system acquires quality information indicating link status between the infrastructure nodes. The link quality information is used in a route determination process in the infrastructure nodes using a predictive procedure. The link quality information includes information about a time varying information of the link status. The predictive procedure uses the time varying information of link status, and a router data packets according to the determined route.

Predictive ad-hoc network routing

The present invention relates to a method for efficient routing in a multiple hop wireless communication network. The routing method comprise the steps of providing link status information by acquiring link status quality between nodes in the network, updating a routing element () with said link status information, determining an appropriate route according to said link status information with respect to traffic content, and routing traffic according to said determined appropriate route.

Method and system for routing traffic in ad hoc networks

The present invention relates to a method for efficient routing in a multiple hop wireless communication network. The invention is characterized in that data packets are routed over transmission paths using the following steps providing link status information by acquiring link status quality between nodes in the network, updating a routing element () with said link status information, determining possible routes with essentially similar link quality status for said data packet, and routing said data packet via the determined routes.

Method and system for efficient routing in Ad Hoc networks

A method is presented for address resolution mapping in a wireless multihop communication network wherein the network is built up by client devices and/or infrastructure devices, network traffic is based on using ARP forwarding and rebroadcasting to locate devices in such a network architecture. The invention also includes devices for such a network and the complete communication system is described.
