Abstract
The overall support and trustworthiness among nodes in wireless environment to relay each other's packets expose them to a wide range of security attacks. Wireless sensor networks (WSNs) introduce a new standard of ambient supervision with many potential applications. The environment of wireless sensor networks and Mobile Ad-hoc networks make them very attractive to the challengers and they become vulnerable to some types of intruders since they are arranged in open and unsecured atmosphere and are comprised of low-priced small devices. This paper introduces an algorithm to design a Mobile Ad-hoc network (MANET) or Wireless Sensor Network (WSN) and compares the effect of different network and physical layer attacks (wormhole, black hole, jamming, byzantine) based on some Quality of service parameters in presence of AODV routing protocol. We simulate various attacks using the network simulator OPNET 14.5 and then analyze them in the basis of some quality of service parameters under AODV routing protocol.
