1. A method for selecting and organizing information for a link performance metric from accumulated and incremental indicators in support of quality of service (QoS) requirements, the method comprising:
- (a) determining a congestion level metric to each hop in an n-hop route based on is link congestion indicator (LCI) metric;
(b) determining a quality level metric, to each of said hops in an n-hop route based on a link quality indicator (LQI) metric;
(c) accumulating and incrementing the quality and congestion level metrics assigned to each hop in said an n-up route; and
(d) constructing a hop k link performance metric for hop k routing decisions from said accumulated and incremented indicators, wherein a link stability indicator (LSI) is a function of LCI, LQI and mobility according to the following equation;
LSIij(t)=(w1Δ
LCIWMA(t),w2Δ
LQIWMA(t),w3mj,w4mj)Where;
Δ
LCIWMA(t)—
weighted average of Δ
LCIΔ
LQIWMA(t)—
Weighted moving average of Δ
LQIm1=mobily1=(#i'"'"'s good links)/(#I'"'"'s link changes).

Abstract
Systems and methods provide adaptability in a mobile ad hoc network (MANET), based on an existing protocol, such as adaptive hybrid domain routing (AHDR). The systems and methods are especially suited for fast changing topologies that may change after a reactive route discovery has been completed.
