Abstract
6LoWPAN (IPv6-based Low-Power Personal Area Networks) link layer is an adaptation layer between Data Link and Original Network layer which becomes a part of network layers, but only with specified network layers. It is used to link High power layers and low power layers. IPv6 allows only packet size of 1280 bytes. As this is impossible to handle in the 127 bye MTU of IEEE 802.15.4 standard, so 6LoWPAN defines a fragmentation scheme to allow such packets. It is a low powered network layer. 6LoWPAN routing is basically divided on the roots of routing decision taken by the adaptation layers or network layer. Internet Engineering Task Force (IETF) implies IPv6 over LoWPAN as methodology in the implementation of TCP/IP protocol in WSNs. 6LoWPAN technology is a burning field in network era as various routing protocols can be used in association with this technology.This paper features IoT protocols that are working at various layers of network protocol mesh and depict the conventions offered by Internet Engineering Task Force (IETF)
and other standard associations.
