Path selection in wireless networks
First Claim
1. A method of selecting a communication path, in a wireless network comprising a plurality of nodes and wireless communication links between the nodes, from a plurality of potential communication paths comprising different combinations of said links from a source node to a target node, comprising the steps of, in the source node:
- determining for each link in the potential communication paths a cost of interference dependent upon a number of nodes affected by a signal sent via the respective link;
determining a total cost for each potential communication path, the total cost being dependent upon combined costs of interference for the links of the respective potential communication path; and
selecting as a communication path from the source node to the target node a potential communication path having a lowest total cost.

Abstract
In a wireless network, a lowest cost path from a source node to a target node is selected from a plurality of potential paths. The source node sums costs for the links of each potential path. For each link, these costs include a cost of interference, dependent on a number of nodes affected by a signal sent via the respective link. The link costs can also include a cost of transmission, dependent upon a data rate for the respective link, and a cost of coordination for transmissions with other nodes of the network.
