Overhead quantifies how much routing and control information is necessary for the application data to reach the destination node. This is very important in Ad Hoc networks because the mobility of nodes makes routing paths change constantly, therefore, the exchange of control and routing information increases. In this work the overhead for AODV, BCHP and DSVD mobile routing protocols is analyzed. Protocol reliability is used like a metric based on overhead behavior. The results show that the overhead can be between 30% to 60% with respect to the total throughput. BCHP is the most effective protocol because with similar expected overhead it has a better level of application information delivered.
