Big Data: Internet of Things (Part-7)

Read my previous post on IOT. Connecting devices and getting raw data from multiples sources, and sending this data to analysis is a major concept in INTERNET OF THINGS. Jobs are growing in this field.

Devices can be connected through Protocols. I want to share some information on advanced IP based Protocols.

The role of IPv6- It is advanced in the Range of internet protocols. The main function is it supports Mobility.

We retain the position that IoT may well become the "killer-app" for IPv6. Using IPv6 with its abundant address spaces, globally unique object (thing) identification and connectivity can be provided in a standardized manner without additional status or address (re)processing—hence, its intrinsic advantage over IPv4 or other schemes

For the IoT as well as for other applications for smartphones and similar devices, there is a desire to support direct communication between mobile nodes (MNs) and far-end destinations, whether such far-ends are themselves a stationary node or another MN. 

Such far-end destination could be, for example, a roving sensor collecting environmental or other data. In order to efficiently maintain reacheability, thus supporting flexible mobility, the goal is to retain the same explicit IP address regardless of the real-time location or specific network elements and/or networks used to support connectivity. This is not easily achievable with IPv4 for a number of reasons; however, MIPv6 described in RFC 3775, "Mobility Support in IPv6" (June 2004), among others, facilitates this task. RFC 3775 is known as the "MIPv6 base specification." RFCs are specifications and related materials published by the Internet Engineering Task Force (IETF). IPv6 mobility, specifically MIPv6, relies on IPv6 capabilities.

RFC 3775 notes that without specific support for mobility in IPv6, packets destined to an MN would not be able to reach it while the MN is away from its home network. In order to continue communication in spite of its movement, an MN could change its IP address each time it moves to a new link, but the MN would then not be able to maintain transport and higher-layer connections when it changes location.
