Abstract 6LoWPAN is one of Internet of Things standard, which allows IPv6 over the low-rate wireless personal area networks. All sensor nodes have their own IPv6 address to connect to Internet. Therefore, the challenge of implementing secure communication in the Internet of Things must be addressed. There are various attack in 6LoWPAN, such as Denial-of-service, wormhole and selective forwarding attack methods. And the Dos attack method is one of the major attacks in WSN and 6LoWPAN. The sensor node’s energy will be exhausted by these attacks due to the battery power limitation. For this reason, security has become more important in 6LoWPAN. In this paper, we proposed a lightweight intrusion detection model based on analysis of node’s consumed in 6LowPAN. The 6LoWPAN energy consumption models for mesh-under and route-over routing schemes are also concerned in this paper. The sensor nodes with irregular energy consumptions are identified as malicious attackers. Our simulation results show the proposed intrusion detection system provides the method to accurately and effectively recognize malicious attacks. Keywords 6LoWPAN

Introduction 6LoWPAN is an acronym IPv6 over Low-Power wireless Area Networks. 6lowpan has defined encapsulation and header compression that allows IPv6 packets to be sent to and received from over IEEE 802.15.4 (Wireless sensor network) based networks. The packet size of IPv6 is much larger than the size of IEEE 802.15.4 MPDU. Thus, the adaptation layer is joining between the network layer and the data link layer to fragmentation and recombination the IPv6 packets into IEEE 802.15.4 radio. There are two routing schemes in 6LoWPAN. And the characteristic of routeover is hop-by-hop. Mesh-under and route-over routing schemes can be considered as end-to-end and hop-by-hop transmission respectively. Hop-by-hop fragmentation and reassembly generates more delay but achieve better fragment arrival ratio. Whereas end-to-end scheme has less latency, but fragment loss has high probability. In 6LoWPAN protocol stack, the last two layers are based on IEEE 802.15.4 physical and data-link layers. Thus, we investigate the energy consumption of IEEE 802.15.4 for the last two layers in the beginning, and then the 6LoWPAN performance analysis in route-over and mesh-under routing schemes are both consideration in this paper.
