A Clock Skew Addressing scheme for Internet of Things

In this paper, we propose a new addressing scheme, namely, the Clock Skew Addressing (CLOSA) scheme, that allows for assigning a unique IPv6 addresses to each node in the Internet of Things (IoT) network. The CLOSA scheme eliminates the need for the inefficient techniques of duplicate address detection and allocation table validation used in most existing addressing schemes. CLOSA guarantees uniqueness by extracting the clock skew of each communication device and converting it into an IPv6 address. Simulation analysis confirms that the proposed scheme can provide significant reductions in communication overheads as compared to the well-known LEADS, SIPA, and DAD addressing schemes.
