The Internet of Things (IoT) is the next generation
technology which is expected to bring a major revolution in the
art of creating smarter environments. In order to uniquely
identify each device in smart environment, a new protocol using
IPv6 over Low-power Wireless Personal Area Network
(6LoWPAN) has been developed which supports management of
sleep cycles of device for power management. Main issues in a
LoWPAN networks include bountiful utilization of bandwidth
due to over dissemination of packets during Neighbor Discovery
(ND) and headers with larger size lead to prodigal power
consumption and short network life. This paper is a survey on
state-of-art of ND techniques like ND++, Context Aware
Resource Discovery (CARD) & HC techniques like Generic
Header Compression, compressed DTLS in 6LoWPAN. The
outcomes of the survey show that there is a prospect of
optimization in ND and HC, with a clear aim to enhance the
efficiency of 6LoWPAN for the low power and low processing
capabilities of IoT devices.
