Abstract
Information-centric networking is a “data-oriented” architecture for Future Internet. Since unicast routing cannot exploit the natural broadcast property of wireless networks and unicast paths may be broken down frequently due to node mobility, broadcast transmission is applied for content delivery in information-centric multihop wireless networks. It will face two key challenges: which nodes that receive the broadcasted packet should forward it, and how to avoid multiple nodes simultaneously transmitting it. In this letter, we solve these two issues by taking node mobility and available link capacity into account. A mobility-based forward node selection algorithm is proposed, which tends to select the less mobility nodes as the forward ones. An available link capacity-based forwarding scheme is proposed, which tends to select forward nodes with larger available link capacities to forward packets. Simulation results demonstrate the effectiveness of the proposed mechanism.
