Reactive and proactive strategies for content update in content-centric and multi-users WSNs

Unlike other networks, WSNs have the particular characteristic of collecting sensed data and forwarding it to the gateway through a one-way communication protocol. In such data-driven networks, it may seem spontaneous to argue to content-centric networking communication architecture. Through exploiting DFCCN-WSNs implemented previously, we focus on two approaches concerning content update in CCN for Wireless Sensor Networks. Techniques used for content update are either reactive or proactive. In addition, our approaches support multi-user scenarios in order to decrease the propagation of the content object in the network. Through extensive simulations, we demonstrate that the two approaches outperforms traditional CCN in terms of end-to-end delay and energy consumption.
