Security is one of the most important concerns of the basic capabilities of mobile networks. Black hole attacks are one of the prevalent attacks with which routing protocols of mobile network s encounter. In this paper, a method has been presented to deal with those attacks, at same time considering the quality of service. In this method, packets are sent through configured reservation paths. Simulation is carried out in opnet and the results revealed that the proposed algorithms yield good results in terms of packet delivery ratio and throughput when compared with the Ad hoc On-demand Distance Vector (AODV) and Dynamic Source Routing (DSR) protocol. Throughput parameters after applying proposed technique, show 6.51 percent increase for AODV, and 61.86 percent increase for DSR. Also the packet delivery ratio shows 96,68 increase for AODV while it is almost zero percent for DSR. Of course it must be noted that some increase has been observed in sending and receiving that will completely be explained in simulation part.
