[hal-01078059] The Role of the Internet of Things in Network Resilience

Disasters lead to devastating structural damage not only to buildings and transport infrastructure but also to other critical infras-tructure such as the power grid and communication backbones Follow-ing such an event the availability of minimal communication services is however crucial to allow efficient and coordinated disaster response to enable timely public information or to provide individuals in need with a default mechanism to post emergency messages The Internet of Things consists in the massive deployment of heterogeneous devices most of which battery-powered and interconnected via wireless network interfaces Typical IoT communication architectures enables such IoT devices to not only connect to the communication backbone ie the Internet using an infrastructure-based wireless network paradigm but also to communicate with one another autonomously without the help of any infrastructure using a spontaneous wireless network paradigm In this paper we argue that the vast deployment of IoT-enabled devices could bring benefits in terms of data network resilience in face of disas-ter Leveraging their spontaneous wireless networking capabilities IoT devices could enable minimal communication services eg emergency micro-message delivery while the conventional communication infras-tructure is out of service We identify the main challenges that must be addressed in order to realize this potential in practice These chal-lenges concern various technical aspects including physical connectivity requirements network protocol stack enhancements data traffic priori-tization schemes as well as social and political aspects
