Summary: 
In this letter, a new routing protocol based on connectivity and link age is presented to reduce the control overhead by avoidance of frequent routes re-establishment and realize rapid route maintenance in mobile ad hoc networks. To achieve this, a new routing metric that combines node's connectivity with link age is introduced. With connectivity parameter, routes are repaired quickly; on the other hand, route lifetime can be prolonged by establishing links with younger link, which is expected to maintain long lifetime rather than older link. Simulation results identify more 20% average link residual time than previous Associativity Based Routing [2].
