TL;DR: This paper investigates the energy cost of cryptographic protocols, both from a communication and a computation point of view, based on practical measurements on the MICAz and TelosB sensors and finds that Kerberos is around one order of magnitude less costly than the ECDH-ECDSA key exchange.
Abstract: Energy is a central concern in the deployment of wireless sensor networks. In this paper, we investigate the energy cost of cryptographic protocols, both from a communication and a computation point of view, based on practical measurements on the MICAz and TelosB sensors. We focus on the cost of two key agreement protocols: Kerberos and the elliptic curve Diffie-Hellman key exchange with authentication provided by the elliptic curve digital signature algorithm (ECDH-ECDSA). We find that, in our context, Kerberos is around one order of magnitude less costly than the ECDH-ECDSA key exchange and confirm that it should be preferred in situations where a trusted third party is available. We also observe that the power dedicated to communications can become a central concern when the nodes need to stay in listen mode, e.g. between the protocol rounds, even when reduced using a low power listening (LPL) protocol. Therefore, listening should be considered when assessing the cost of cryptographic protocols on sensor nodes.

TL;DR: Challenges related to service growth strategies, as well as strategies involving deservitization or a retreat from service offers are examined, showing that these strategies have been pursued for more than fifty years and that future research must elucidate “softer” issues such as leadership and business logic.

TL;DR: Novel findings are discussed that may partly explain how the microbial community participates in the development of the fat mass development, insulin resistance and low-grade inflammation that characterise obesity.
