A Study on Protocol Stack in 6LOWPAN Model
Due to recent advances of heterogeneous network and the emergence of Internet of Things (IoT), wireless personal area networks including wireless sensor networks are assumed to be part of the huge heterogeneous network. This calls for a smooth integration between the higher network layer protocols Internet Protocol version 6 (IPv6) and the lower Media Access Control (MAC) layer protocol IEEE 802.15.4. IEEE 802.15.4 is a standard that specifies the physical layer and MAC layer for Wireless Personal Area Network (WPAN). This standard is suited for Low-Rate Wireless Personal Area Networks (LR-WPANs), a constrained network of tiny, low power, low rate, small size memory with low computation and communication capabilities.
