Study of performance TORA and OLSR Routing Protocols Under the influence of the Black Hole Attack in AD-HOC Networks with High TrafficLoad

Mobile Ad-Hoc Networks are used for data transfer. The nodes of such networks do not require presetting. They are characterized by dynamic data transfer during their movement of the nodes. MANET could be targeted by potential security breaches. Black hole attack is one of the serious attacks targeting wireless AD_HOC networks through a false point whichcan absorb data and send them to another place or neglect them. This is due to the lack of central control node which is able to manage communications. This research investigates the effects of the black hole on the performance of hybrid routing protocol Temporally Ordered Routing Algorithm (TORA) and proactive routing protocol Optimized Link State Routing (OLSR) for a variable number of mobile nodes in different speeds in a high load environment.

Integrating security keys exchange in the secure routing in AODV protocol

Mobile ad-hoc Networking MANETS is a promising concept to provide flexible, adaptive, and reconfigurable architecture, cost effective solution.In the mobile ad hoc network security is the basic concern for network functions work properly.Routing is the corner stone in Mobile ad-hoc Networks, A lot of known vulnerabilities and security threats can be exploited to attack routing messages, so it is important to provide secure routing protocol for MANETs.In this paper, we present a secure extension for ad-hoc On Demand Distance Vector Protocol (AODV). The default routing protocol for MANETs. The proposed protocol ensures that discovery of the route between the nodes is functioning properly and securely, achieving mutual authentication between nodes, routing message integrity, generating a security key of data sent and exchanges it securely to ensure confidentiality and all of these are in one stage. By this we save in wireless band, resource consumption, preventing duplicate of authentication algorithms.
