OEFS: On-Demand Energy-Based Forwarding Strategy for Named Data Wireless Ad Hoc Networks

The futuristic Internet paradigm, named data networking (NDN), was recently introduced to solve the severe issues of current Internet architecture, such as complex usage, poor resource utilization, inefficient mapping, scalability, location dependence, and so on. Communication in NDN is based on content names decoupling from their locations. NDN also provides strong built-in functionalities, like multi-path routing, security primitives, flow balance mechanisms, and in-networking caching. Similarly, NDN-based mobile ad hoc networks are highly dynamic in nature whereby the participating nodes have experienced highly challengeable environments and constraints, such as channel fluctuations, intermittent connectivity, and low battery power. In this environment, if a node has limited residual energy, after sending a few packets, it will die soon. Furthermore, all of its pending request entries are also destroyed, which further exacerbates the communication process. To cope with this problem, we have proposed a novel protocol called the on-demand energy-based forwarding strategy (OEFS) that takes the residual energies of the nodes into account during the entire communication process. For the performance evaluations, we have used NDNSIM, which is specially designed for NDN-based networks. The simulation results show that the our OEFS outperform the existing state-of-the-art protocol in terms of content download time, interest retransmissions, the total number of Interest propagation, and data redundancy in the network. We also find the effect of OEFS on the energy threshold and show that OEFS enables mobile nodes to consume less amount of energy
