ABSTRACT
Internet of Things (IoT) has been receiving a lot of interest around the world in academia, industry and
telecommunication organizations. In IoT, many constrained devices can communicate with each other
which generate a huge number of transferred packets. These packets have different priorities based on the
applications which are supported by IoT technology. Emergency applications such as calling an
ambulance in a car accident scenario need fast and reliable packets delivery in order to receive an
immediate response from a service provider. When a client sends his request with specific requirements,
fast and reliable return contents (packets) should be fulfilled, otherwise, the network resources may be
wasted and undesirable circumstances may be counted. Content-Centric Networking (CCN) has become a
promising network paradigm that satisfies the requirements of fast packets delivery for emergency
applications of IoT. In this paper, we propose fast packets delivery techniques based on CCN for IoT
environment, these techniques are suitable for urgent packets in emergency applications that need fast
delivery. The simulation results show how the proposed techniques can achieve high throughput, a large
number of request messages, fast response time and a low number of lost packets in comparison with the
normal CCN.
