Content centric routing in IoT networks and its integration in RPL

Internet of Things (IoT) networks can be used for many applications across different industry domains in- cluding infrastructure monitoring, civil service, security and surveillance applications etc. However, gath- ering large amounts of data from such networks including images and videos often cause traffic con- gestion in the central network area. In order to solve this problem, we proposed the content centric routing (CCR) technology, where routing paths are determined by content. By routing the correlated data to intermediate relay nodes for processing, a higher data aggregation ratio can be obtained, hence effectively reducing the traffic in the network. As a result, significant latency reduction can be achieved. Moreover, redundant data transmissions can also be eliminated after data aggregation which reduces the energy consumption spent predominantly on wireless communication thereby conserving limited battery.
