Information-Centric Networking (ICN) is being considered as a promising approach to address the issues and shortcomings of existing IP addressbased networking models and cater high density of users and devices of future communication paradigm. ICN models are based on naming the contents to deal address-space scarcity and support upcoming massive connections. It allows accessing of contents vial name-based routing and caching the content at intermediate nodes to provide reliable, efficient and self-certifying contents to ensure stringent security requirements. Obvious benefits of ICN in terms of fast and efficient data delivery and improved reliability makes ICN as highly promising networking model for Internet of Things (IoTs). IoTs foremost target is to connect billions of things in a way to reduce human involvement and automate machines. Among many challenges, one key challenge is how to name and address the IoT contents and devices efficiently. Thus, this thesis introduces the ICN ( i.e., more specifically Named Data Networking (NDN) and Content Centric Networking (CCN)) for both IoT devices and contents and presents two novel naming mechanisms and one holistic forwarding scheme equipped with security, heterogeneity and scalability. Also, this thesis reclassifies IoT applications and presents their fourteen categories. From this new categorization, IoT-based Smart Campus (IoTSC) scenario is selected to design the naming and forwarding schemes due to its true representation for IoT. Firstly, a CCN-based hybrid naming scheme is proposed which names the contents using hierarchical and flat components to support both push and pull communication and introduced two transmission modes namely (1) unicast mode and (2) broadcast mode to address loop problem associated with CCN. Simulation results demonstrate that proposed scheme significantly improves the rate of interest transmissions, number of covered hops, name aggregation, and reliability along with addressing the loop problem. Further as an extension to the first scheme, NDN-based hybrid naming scheme is proposed which names the IoT devices and content using hierarchical, flat and attribute components to support both push and pull traffic models. Then, on the basis of extended NDN-based hybrid naming scheme, IoT traffic types are defined using the listed activities in IoTSC. Holistic forwarding schemes are proposed for NDN-IoT consumer, producer and content routers which provide machine type communication (MTC) with push and pull communication models enabled. These forwarding schemes use another OnboardICNg security scheme which is designed to authenticate and authorize the devices to perform asked actions. These schemes enable NDN-IoT producer to send critical content or updates of subscribed content to NDN-IoT consumer through content router(s). Moreover, NDNIoT consumer is enable to send message to perform any action or setting value of any parameter of NDN-IoT producer. These schemes are also implemented in ndnSIM and evaluated against legacy NDN in terms of interest satisfaction rate, latency and number of transmissions.
