| In mobile ad hoc networks, the absence of infrastructure and the consequent absence of authorization facilities impede the usual practice of establishing a practical criterion to distinguishing nodes as trusted and distrusted. Since all nodes in the MANETs would be used as router in multi-hop applications, secure routing protocols have vital rule in the security of the network. So evaluating the performance metrics of secure routing protocols and calculating the overhead of security design is very important in network engineering. In this paper the effects of Black hole attack on two different types of routing, OLSR as proactive routing protocol and AODV as reactive routing protocol are considered. In addition, the performance metrics of ordinary routing protocols (AODV and OLSR) are compared with a new secure routing protocol MAODV, in which neighbors of node help him to distinguish a trusted node. Finally, the simulation results depict the end-to-end delay of a network under black hole attack with different type of routing protocols, AODV, OLSR and MAODV. The simulation results illustrate good comparison of network performance parameters for different conditions such as node mobility and number of nodes. | ||
