Secured routing over manet using Enhanced Secured Routing (ESR)

Security problem in MANET has been prevailing even after several researches by the various authors. Since application of security mechanism affects the system performance very much therefore there is always scope for further research in this area. Another major cause is fast technology growth in the area of MANET. Recent researches are focusing on another mechanism of security which involves trust management or Identity Based Cryptography (IBC) which has improved the security of the MANET to a great extent. This paper provides a modified trust mechanism for increasing the security over MANET using IBC along with reduced processing time and load on the system. It assigns keys to every incoming node which is used only once per communication between the nodes and hence high performance is assured.
