The rapidly increasing connectivity demands of both fixed and mobile devices on the internet have motivated a clean-slate redesign of existing core and radio access networks. The advent of content-oriented applications such as social media applications, on-demand video streaming services, interactive gaming applications, etc. has exposed the limitations in the existing host-centric Internet Protocol (IP) based internet architecture. Information-Centric Networking, a clean-slate future internet architecture, has been extensively researched to show its effectiveness in its handling of content-centric applications in the core-network. This thesis aims to propose ICN based radio access network architecture, "I-MAC", which enables the integration of ICN identifiers and semantics with radio access network in order to achieve efficiency gains in capacity-limited wireless networks which are used by an increasing proportion of Internet traffic. Additionally, the use of a Local Name Resolution Table (LNRS), maintained by each base station in LTE, called as Evolved Node B (eNodeB), to seamlessly map the device GUID (globally unique identifier) with the corresponding radio network identifier allocated during each attach process is also suggested. This design is further extended to specifically support push and pull-based multicast transmissions at the last hop by a novel control signaling which incorporates physical control and data channels of existing cellular architecture. The verification of this design is done via a special pull-based multicast use case which takes into account the characteristics of highway-tunnel topography, traffic conditions, and user behavior. Through extensive simulations using NS-3 coupled with SUMO (Simulation for Urban MObility), it is shown that significant multicast gain is achieved at the eNodeB and considerable amount of bandwidth is saved. The simulation results of this design show that the temporal correlation among many delay tolerant user requests induces about 45% aggregation of user requests, costing the user a delay of merely a second. The results also show the suitability of this design for massive IoT applications where the device uptime is reduced by a factor of twenty from the current cellular multicast architecture, SC-PTM, thus providing considerable device power savings. Analytical measurements show spectral efficiency of this work with a control data occupancy in data channel of 0.07% in contrast with that of SC-PTM which has 1.32%, thereby, ensuring that user data gets a significant share of the bandwidth. In addition, parametric evaluations to check the sensitivity of the design to various parameters introduced in the model have also been performed.
