1. A method in a mobile ad hoc router that is within a mobile ad hoc network, the method including:

  • determining by the mobile ad hoc router a relative proximity of at least one neighboring node relative to the mobile ad hoc router, the relative proximity indicating a relative reliability of a wireless communication link between the mobile ad hoc router and the at least one neighboring node; and

    initiating by the mobile ad hoc router a convergence of network routes according to a prescribed routing protocol, that includes the neighboring node, in response to the mobile ad hoc router determining that a determined variation in the relative proximity has reached a prescribed minimum interval of stable relative proximity;

    wherein the mobile router determines whether the determined variation in the relative proximity reaches the prescribed minimum interval of stable relative proximity based on;

    initiating a stability timer in response to the determined variation in the relative proximity falling below a prescribed stability threshold, anddetermining whether the determined variation in the relative proximity remains below the prescribed stability threshold for the prescribed minimum interval according to a prescribed minimum time interval.
