OODC: An Opportunistic and On-Demand Forwarding Mechanism for LPWA Networks

The single-hop star-of-stars topology of current Low Power Wide Area Network (LPWAN) is simple and robust but still lack of network coverage because of signal attenuation. We present a forwarding mechanism to increase the coverage and re-liability of LPWAN. Two key characteristics of our approach are on-demand and opportunistic forwarding. While most previous studies adopt […]

CLOF: Contribution Level Based Opportunistic Flooding for Multihop Wireless Networks

In this study, we propose a contribution-level-based opportunistic flooding for multihop wireless networks. Traditional flooding techniques typically use fixed routing and predetermined relay nodes based on the assumption of fixed and reliable links. However, because of the inherent instability of wireless links, these approaches typically lead to fragile and unreliable broadcasting. To overcome this problem, […]
