Ad hoc networks are self-organizing and self-configuring networks. The wireless ad hoc networks do not have fixed infrastructures. The mobile Ad hoc networks (MANET) do not require a predefined configuration. Mobile stations in wireless ad hoc networks move around in the network, thus the topology of a MANET can be very dynamic due to the mobility of mobile nodes. Because of the dynamic topology and wireless link characteristics, the Quality of Service (QOS) support in MANETs is a very challenging task. Routing algorithm is a very important mechanism for QOS guaranteeing in networks. In this paper, we present a QOS routing algorithm, called Energy Efficient and QoS aware routing protocol (EQRP), which is an extension to the AODV protocol, we introduce more metrics in addition to the number of hops used by AODV protocol and we give a weight function using several parameters. The EQRP protocol selects optimal routes and also provides Quality of Service and fault tolerance.Results obtained by a simulation show that EQRP allows obtaining some important advantages that makes it increases the throughput and decreases the delay and decreases the route discovery time.
