Classes
class	AntHistoryTracker

struct	AntHop
	One entry on an ant's visited-node stack: a node and the trip time the ant took to reach it from the previous hop. More...

struct	AntMessage
	Complete, copyable description of an ant packet. More...

class	AntRouterLogic

struct	ClassicMetric
	The canonical AntHocNet metric (Eq.2): blend the path-time estimate with the hop-count estimate and invert. More...

struct	Config

struct	EnergyMetric
	The energy-aware metric (#145, the BeeAdHoc / EEABR line): a hop costs 1 / e, where e is the residual energy fraction of the node that forwards over it, floored so an almost-empty node costs a large but finite amount. More...

class	GenerationTracker
	Multipath acceptance filter for reactive forward ants ([1] §3.1, issue #96). More...

struct	HelloDest
	A (destination, pheromone) advert carried by a hello ant for building the virtual pheromone table. More...

struct	HopSignals
	What a node knows about one of its own links when a link-quality metric prices it (#181, #145). More...

class	IClock
	Source of simulation time (seconds). More...

class	IEnergy
	This node's residual energy (#145): the fraction of its initial battery left, 0..1. More...

class	IKinematics
	This node's own position and velocity (#573, ADR-0025). More...

struct	ILinkMetric
	Maps an observation to a pheromone (goodness; higher == better). More...

class	ILinkQuality
	Per-neighbour link quality (#181, ADR-0024). More...

class	ILinkState
	Node-local MAC-layer signals for the congestion-aware per-hop metric (item 10/A2, [1] §3.2). More...

class	INeighborProvider
	Current set of one-hop neighbours, as seen by the link layer. More...

class	IRng
	Source of randomness. More...

class	IRouterObserver
	Optional observer the core notifies of routing events (item 15). More...

class	ITimerScheduler
	Deferred-execution port for periodic ant generation / table maintenance. More...

struct	Kinematics
	A node's position (m) and velocity (m/s) in the adapter's Cartesian frame (ADR-0025). More...

struct	LinkObservation
	What a backward ant knows about the path from this node to the destination. More...

class	PheromoneEngine

class	PheromoneTable

struct	RouteDecision

class	ShortestPathGraph

struct	SinrMetric
	The SINR metric (#181), the one the 2007 thesis used for every headline result: "we normally use the signal-to-interference-and-noise ratio metric, as this gave the best results" (§4.2.6). More...

Typedefs
using	NodeAddress = std::int32_t
	Network-layer node address.

using	Time = double
	Simulation time, in seconds.

using	VisitedPath = std::vector< AntHop >

Enumerations
enum class	AntType : std::uint8_t { Hello = 0x01 , Reactive = 0x02 , Proactive = 0x04 , Repair = 0x08 , LinkFail = 0x10 }
	Ant role. More...

enum class	AntDirection : std::uint8_t { Up = 0x11 , Down = 0x12 }
	Travel direction. More...

enum class	RouteAction { None , Unicast , Broadcast , Queue , Deliver , Drop , DiscardPending }

Functions
double	linkExpiryTime (const Kinematics &a, const Kinematics &b, double range)
	Seconds until `a` and `b` are `range` metres apart, moving as they move now.

double	linkLifetimeWeight (double let, double horizon, double floor)
	The next-hop weight for a link expected to live `let` seconds: 1 at or beyond `horizon`, falling linearly below it, never under `floor` (a short link is discouraged, not removed: if every link is short the choice among them is the pheromone's).

double	sinrLinkCost (double sinrDb, double criticalDb, double penalty)
	Eq.

Variables
constexpr NodeAddress	kInvalidAddress = -1
	"No such node / no route" sentinel, mirroring the legacy use of -1.

Typedef Documentation

◆ NodeAddress

using anthocnet::core::NodeAddress = typedef std::int32_t

Network-layer node address.

Matches the width of ns-2's nsaddr_t and ns-3's 32-bit IPv4 address payload.

Definition at line 21 of file types.h.

◆ Time

using anthocnet::core::Time = typedef double

Simulation time, in seconds.

Definition at line 24 of file types.h.

◆ VisitedPath

using anthocnet::core::VisitedPath = typedef std::vector<AntHop>

Definition at line 30 of file visited_path.h.

Enumeration Type Documentation

◆ AntType

enum class anthocnet::core::AntType : std::uint8_t

strong

Ant role.

Values match the legacy ANTTYPE* bit flags so existing traces remain comparable.

Enumerator
Hello
Reactive
Proactive
Repair
LinkFail	link-failure notification (payload in helloDests).

Definition at line 25 of file ant_message.h.

◆ AntDirection

enum class anthocnet::core::AntDirection : std::uint8_t

strong

Travel direction.

Up = forward (toward destination), Down = backward (retracing the path to reinforce it).

Enumerator
Up
Down

Definition at line 35 of file ant_message.h.

◆ RouteAction

enum class anthocnet::core::RouteAction

strong

Enumerator
None	Nothing to do.
Unicast	Send `message` to `nextHop`.
Broadcast	Link-layer broadcast `message`.
Queue	Hold the data packet pending a route to `nextHop`/dst.
Deliver	Destination reached: hand to the local transport.
Drop	Discard (loop, TTL, no route).
DiscardPending	Local repair timed out ([1] §3.5, D6): discard the data packets queued for destination `nextHop`.

Definition at line 21 of file route_decision.h.

Function Documentation

◆ linkExpiryTime()

double anthocnet::core::linkExpiryTime	(	const Kinematics &	a,
		const Kinematics &	b,
		double	range
	)

inline

Seconds until a and b are range metres apart, moving as they move now.

+inf when they never separate (same velocity, or approaching for ever is impossible: a quadratic with a > 0 always has a root, so +inf means zero relative velocity inside range). 0 when they are already out of range.

◆ linkLifetimeWeight()

double anthocnet::core::linkLifetimeWeight	(	double	let,
		double	horizon,
		double	floor
	)

inline

The next-hop weight for a link expected to live let seconds: 1 at or beyond horizon, falling linearly below it, never under floor (a short link is discouraged, not removed: if every link is short the choice among them is the pheromone's).

Definition at line 44 of file link_lifetime.h.

◆ sinrLinkCost()

double anthocnet::core::sinrLinkCost	(	double	sinrDb,
		double	criticalDb,
		double	penalty
	)

inline

Eq.

4.11: 1 for a link whose SINR is above criticalDb, penalty for one at or below it. No sample (NaN) counts as a good link (ILinkQuality).
