	True when the metric's per-hop cost is a link-quality cost (#181) rather than a time.

virtual double	hopCost (const HopSignals &) const
	The cost of one of this node's own links, for a metric that usesLinkQuality(): the per-hop value a node writes into the hop a backward ant came over, and adds wherever it extends a path by one hop.

Member Function Documentation

◆ pheromone()

virtual double anthocnet::core::ILinkMetric::pheromone ( const LinkObservation & obs ) const

pure virtual

Implemented in anthocnet::core::ClassicMetric, anthocnet::core::SinrMetric, and anthocnet::core::EnergyMetric.

◆ usesLinkQuality()

virtual bool anthocnet::core::ILinkMetric::usesLinkQuality ( ) const

inlinevirtual

True when the metric's per-hop cost is a link-quality cost (#181) rather than a time.

The router then has each node put its own estimate of the link it received a backward ant over into that hop of the retraced path (thesis §4.2.2: "the reactive backward ant reads at each node i the local estimate c_i^n of the cost to go from i to the next hop n"), and uses the same link cost wherever it adds one hop to a path.

Reimplemented in anthocnet::core::SinrMetric, and anthocnet::core::EnergyMetric.

◆ hopCost()

virtual double anthocnet::core::ILinkMetric::hopCost ( const HopSignals & ) const

inlinevirtual

The cost of one of this node's own links, for a metric that usesLinkQuality(): the per-hop value a node writes into the hop a backward ant came over, and adds wherever it extends a path by one hop.

Never called for a metric that does not use link quality.
