A Review on Security Issues and Encryption Algorithms in Mobile Ad-hoc Network

Now-a-days in wireless devices, Mobile Ad-hoc Network become an important part for communication for mobile devices. Mobile Ad-hoc Networks (MANETs) allow wireless nodes to form a network without requiring a fixed infrastructure. Due to the absence of the central infrastructure, we face many challenges or problems during sending data from one mobile node to another mobile node. In this paper, we discuss about features of MANET, their advantages and disadvantages and security issues and their solutions in the mobile ad-hoc network. Cryptography is the way of hiding information during transmission over a channel. There are lots of cryptographic algorithms available to protect our data from intruders.RSA also one of the effective public key cryptographic algorithm which needs time and memory.
