This paper proposes a novel forwarding algorithm for lossy wireless sensor networks (WSNs), which increases network performance in terms of received traffic at the sink (R<SUB>0</SUB> pcakets/s) and network lifeline. Due to lossy wireless links, each sensor node forms around itself three different communication regions, each characterized by different packet reception rate (PRRs). An optimal forwarding algorithm is derived by solving a linear programming problem (LPP) with the objective of maximizing R<SUB>0</SUB> while satisfyung the essential constraint of balancing energy consumption. From the results of the LPP, a new metric combining hop distance (HD) and PRR was developed to formulate a novel forwarding algorithm called direct and multi-hop data forwarding with lossy awareness (DMFLLA) algorithm. The results of simulation indicate that the Proposed DMFLLA algorithm outperforms the conventional algorithms with respect to R<SUB>0</SUB> and network lifetime.
