چکیده
Wireless adhoc netwok is a decentralized type of wireless network, it does not rely on a preexisting infrastructure. These types of networks are used in situations where temporary network connectivity is needed. This research paper explores the effect of using directional antennas in ad hoc network. Antenna patterns of omni directional and directional antenna have been developed using the OPNET Modeler 14. 0. Simulation scenarios have been created for both antennas with three routing protocols AODV, GRP, OLSR. From the results of the simulation, we observe that data dropped rate (Retry threshold), Load and Delay graphs in case of directional antenna network shows better performance than omni directional antenna network. Among three routing protocols which we have used in our network model, OLSR routing protocol shows better performance and high throughput for directional antennas as compare to AODV and GRP routing protocols.

In mobile ad hoc networks, the absence ofinfrastructure and the consequent absence of authorizationfacilities impede the usual practice of establishing a practicalcriterion to distinguishing nodes as trusted and distrusted.Since all nodes in the MANETs would be used as router inmulti-hop applications, secure routing protocols have vital rulein the security of the network. So evaluating the perf...

Mobile Ad Hoc Networks (MANETs) are receiving a significant interest and are becoming very popular in the world of wireless networks and telecommunication. MANETs consist of mobile nodes which can communicate with each other without any infrastructure or centralized administration. In MANETs, the movement of nodes is unpredictable and complex; thus making the routing of the packets challenging....
