A Framework for Wireless Sensor Network Security

Wireless Sensor Networks (WSNs) have become prolific in the past few years as low cost and easily deployable means to collect environmental data. With the increased scope of applications of WSNs it is imperative to assure security of the network itself against attacks, as well as to assure privacy and integrity of the data that is being collected and transmitted through the network. The I-TRM (Integrated Technical Reference Model) of a WSN has been proposed to standardize these network models in a three faced pyramid, where the three faces are Control, Information and Behavior protocol stacks. In this paper, we expand the I-TRM into a four faced pyramid, where the fourth face is the Security Centric face. This paper introduces the proposed expansion at a high level, with system level requirements of the newly expanded I-TRM. Future papers will present more detailed specifications of the new I-TRM.
