An Efficient & Secure Approach under Multiple Attack Prone MANET

Security or secure communication is the most difficult problem in MANETs because of its many shortcomings. The lack of authorization functionality, the lack ofinfrastructure in the network environment, and dynamically random node movement are a few of the flaws or distinctive characteristics that make MANETs susceptible to various attacks. Due to energy limitations brought on by nodes’ mobility, the network uses power inefficiently and experiences battery issues. This leads to a requirement for improved security effectiveness. Multiple attacks have a more severe effed on MANETs than a single targeted attack. There have been numerous types of secure algorithms and protocols developed as a result of the rising demand for MANET usage, but there are still no fully secure protocols that make communication easy. This study now presents an approach to detect multiple attacks blackhole, grayhole and wormhole attacks on MANETs.
