Study on the wireless sensor networks routing for Low-Power FPGA hardware in field applications

Abstract

Very intelligent compact sensors with low-power and inexpensive solutions have been created because of the industrial revolution and subsequent advancements in electrical technology and wireless communications. Modern innovative enhancements have been made for the utilization of small, low-price, and low-power wireless communication devices with fast processing capabilities. The sensor node communication and routing play a significant role in the configuration of a specific WSN environment. There are three types of WSN routing: proactive, reactive, and hybrid. DSDV and OLSR are two proactive routing technologies. AODV and DSR are reactive routing technologies. DSDV Routing requires a progress update of its routing tables even when the network is not in use, which uses battery power and generates negligible data. As a result, this protocol is inappropriate for networks that are both huge in scope and very dynamic. OLSR maintains track of all potential solutions in a routing table. The overhead from control messages rises as there are more mobile hosts. It requires more processing power than other protocols while looking for alternate routes. The DSR protocol relies on the minimal hop count parameter to pick the way without considering other parameters that impact routing algorithm performance, such as energy consumption, residual energy, and connection stabilities. The FPGA realization provides an ascendable computing environment for WSN planning in a specific region. The research articles emphasize the hardware chip simulation and analysis of these routing protocols which can be further applied for field applications and configuration The network performance is evaluated using several performance metrics such as throughput, control overhead, delay, packet delivery ratio, and power consumption. This study offers a key method for creating FPGA-based power estimation and verification models for a WSN planning environment.
