A Literature Review of Enhancing Security in Mobile Ad-Hoc Networks Using Trust Management Security Scheme
Rajshree Ambatkar | Purnima Selokar 
Abstract: A mobile ad hoc network (MANET) is formed with wireless mobile devices (nodes) without the need for existing network infrastructure. Security design in MANET (Mobile advoc network) is complicated because of its features including lack of infrastructure, mobility of nodes; dynamic topology and open wireless medium. Due to this MANET suffer from many security vulnerability. To enhance the security, it is very important to rate the other node which is trustworthy. Hence a unified trust management security scheme is used. In trust management security scheme, the trust model has two components: direct observation and indirect observation. In direct observation, trust value is calculated from an observer node to observed node. On the other hand, indirect observation is also referred as secondhand information which is obtained from neighbor nodes of the observer node; the trust value is calculated between them. By combining these two components in the trust model, a more accurate trust value is obtained. This will help to improve throughput and packet delivery ratio in the network.
