AN APPROACH TO ANALYZE RISK OF AODV AND OLSR ROUTING FOR MOBILE AD HOC NETWORK

A temporary network is possible to establish anywhere for maintaining proper communication. In any organization, mine site and other places, where the communication is required and form a small area or zone. Mobile Ad hoc Network (MANET) is a good choice for communication. Communication is possible by using laptops and mobile phones. The senders communicate with the receiver in a few meter range and transfer the information to the receiver. The topology is purely dynamic and also the risk of connection failure is more due to communicating in an open environment. The connection establishment is a critical task because the nodes are continuously moving in a limited area. In this paper, the risk effect is measured through the performance of AODV and OLSR routing protocol. Transference, Mitigation, Avoidance, Acceptance are the four types of risk that affect network performance. The risks are the factors that are affected the routing performance. These risks are shows the security, symmetric link availability, power, and next node availability or network establishment in communication that is the main cause of data dropping in MANET. These risks affect is shown clearly by measure the routing performance of AODV and OLSR protocols. The risk factors are more affected by the performance of the OLSR protocol as compared to the AODV protocol in MANET. The degradation in packet receiving is more in the OLSR protocol. The information leakage, energy leakage, path instability and node mobility are showing their effect in OLSR routing, which means the OLSR routing approach is easily affected by the risks in MANET as compare to AODV protocol.
