Initiation of routing convergence by a mobile router in a mobile ad hoc network in response to reaching a minimum interval of stable relative proximity between at least one neighbor
First Claim
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 relative proximity reaching a prescribed minimum interval of stable relative proximity.

Abstract
Each mobile router in a mobile ad hoc network is configured for measuring a minimum interval of stable relative proximity (SProxMIN) between at least one neighbor before initiating convergence of a routing protocol. The minimum interval of stable relative proximity requires any variation in relative proximity between at least one neighbor to be stabilized below a prescribed stability threshold (S) for the prescribed minimum interval (SProxMIN) before initiating convergence of a routing protocol. Hence, mobile routers in a mobile ad hoc network can be configured to avoid prematurely initiating reconvergence according to a routing protocol due to an instability introduced into the network.
