Extenuate the DOS Attacks in OLSR Protocol using Novel Trust Management Method

  Ms. Dhivya Bharathi V,  Mrs. Sagarika Behera

Mobile Ad-Hoc Networks (MANET) mainly specified for routing efficiency, the resulting protocols tend to be vulnerable to various attacks. In this network, an application contains very sensitive and secret communication since the MANET is in dynamic nature to provide a secure data transmission is difficult. A huge number of methods have been proposed for different types of attacks, however, these methods compromise routing efficiency or network overload. The DOS attack against the Optimized Link State Routing protocol (OLSR) known as the node isolation attack exist when topological information of the network is exploited by an attacker who is able to isolate the victim from the network and deny communication. In this paper, we introduce a novel Trust management approach to OLSR protocol knows as TOLSR to defend the OLSR protocol from node isolation attack Through extensive experimentation we demonstrate that the proposed method prevents more of attacks, the reduces the traffic overload and increases the performance. Lastly, we suggest that this type of solution can be used to other attacks
