Abstract--An important characteristic of a mobile ad hoc
network routing protocol is connectivity maintenance. The
protocol's ability to maintain routes and react to topology
changes due to link failures affects the delay, packet loss, and
throughput of real-time applications. However, the time
required to recover from a link failure in the current AODV
protocol is too long for real-time applications. The objective
of this paper is to develop a mechanism to allow fast response
to link breaks to enable real-time communications, such as
Voice over IP. We propose AODVM-ALARM, an adaptive
