Data forwarding algorithm over lossy links in wireless sensor networks

摘要

This paper proposes a new forwarding algorithm over lossy wireless link that increases network performance in terms of received traffic at the sink (R _(0) packets/s) and network lifetime in wireless sensor networks (WSNs). Due to lossy wireless links, each sensor node forms around itself three different communication regions, each characterized by different packet reception rates (PRRs). The results of simulations indicate that, the proposed FOLLA (Data forwarding with lossy link awareness) algorithm outperforms the conventional algorithms with respect to R _(0) and network lifetime.
