Fast and Power-Efficient Hardware Implementation of a Routing Scheme for WSNs
One of the most rapidly expanding areas, nowadays, in networking systems is the Wireless Sensor Network (WSN). Typically WSNs rely on multi-hop routing protocols which must be able to establish communication among nodes and guarantee packet deliveries. In this paper, the authors present a novel approach for the implementation of the WSN routing protocols, which takes advantage of modern FPGAs in order to provide faster routing decisions while consuming significantly less energy than existing systems. Despite their focus on a particular routing protocol (GPSR), the platform developed has the additional advantage that due to the re-configurability feature of the FPGA it can efficiently execute different routing protocols based on the requirements of the different WSN applications.
