Abstract

Systems and methods related to distributed route determination through a multi-hop wireless network based on multiple route metrics or properties are disclosed. In some embodiments, a method of operation of a network node comprises identifying a subset of neighbors of the network node in a wireless network based on: (a) link weight(s) for links from the network node to at least some of the neighbors of the network node with respect to route metric(s) and (b) defined limit(s) for the route metric(s). The method further comprises obtaining second link weights for the links from the network node to at least the subset of the neighbors with respect to a second route metric, and identifying from the subset of the neighbors, an optimal next hop neighbor for the network node. In this manner, multiple route metrics are taken into consideration in manner that is computationally efficient.

Description

[0001] related application [0002] This application claims the benefit of Provisional Patent Application Serial No. 61 / 909,267, filed November 26, 2013, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to routing in wireless networks, and in particular, to distributed routing in multi-hop wireless networks using more than one routing metric. Background technique [0004] Dense deployments of base stations or wireless access nodes can be used to handle the exponential growth in wireless data traffic. The feasibility of dense deployment of wireless access nodes is based on the existence of a backhaul network that can provide high data rate transmission to each individual access node in the network. From the perspective of maximizing capacity, fiber-based backhaul solutions are desirable and suitable for new constructions. However, the cost of installing new fiber to every access node in a ve...
