An analysis of security and communication constraints of IPv6-based Sensor Networks

Wireless Sensor Networks (WSN) offer a significant potential for ubiquitous monitoring and control in future internet-connected pervasive systems architectures. This can be achieved through seamless integration along existing networking devices and systems, while taking account the data-driven nature and security constraints imposed upon such low power, efficient embedded networked platforms. We argue that only through a combined security and communication approach can the relevant goals be achieved, by considering security issues as an integral part of high level layers of the protocol stack. This paper presents an analysis of security and communication constraints of IPv6-based wireless sensor networks at the network and transport layer. Leveraging the Contiki operating system for resource constrained devices along with the ContikiSec security layer and RPL, IPv6 Protocol for Low Power and Lossy Networks, helpful insight is achieved for evaluation and deployment. The results of the analysis are discussed and functions of its modules are explained. This opens up the path towards robust implementation in real world applications following comparative experimental work on simulated and emulated mote platforms.
