A Review on Security and Scalability in M2M

In this paper, we review the scalability and security issues in machine-to-machine(M2M) communications and their proposed solutions. Numerous methods and protocols are available for addressing the issue of security and scalability in M2M communications. Security aspect of the M2M communication should be addressed from the beginning itself so that the implementation of various applications become feasible. All the requirements for interconnection of thousands of devices, M2M networks should have huge scalability for low-cost connectivity according to the need. With the help of a scalable M2M network, cost efficiency becomes higher and consumption of power also decreases.
