ICN-WiMAX: An Application of Network coding based Centrality-measures caching over IEEE 802.16

To provide broadband access services to customers, which resides residential and enterprise field, WiMAX worldwide interoperability for microwave access is one of the famous wireless technology nowadays. In the real world, the number of users making the request for access content item are high. Therefore, by exploiting the features of an Information-centric network (ICN) such as caching capability of content routers, can be used to reduce the bandwidth consumption using centrality measures with network coding. In this way, a user can access the content item using their neighboring content routers rather than the server. Also, It requires scheduling algorithm in the MAC layer of its protocol stack for allocation of the bandwidth. Therefore, to avoid starvation, to maintain fairness and to provide high data speed among users with continuous service there is a need of scheduling algorithm in the uplink layer of the WiMAX. One of the widely used scheduling algorithms is the earliest deadline first (EDF) but it contains certain performance limitations. In this paper, we propose a Heuristic earliest deadline first (H-EDF) uplink scheduler in the MAC layer of the ICN-WiMAX such that it can efficiently schedule user's request and provide a fairness in the ICN-WiMAX system. Further, we assess the performance of ICN-WiMAX using H-EDF scheme via simulations and provide a detailed analysis of its outcomes.
