Energy-Efficient Routing in Wireless Sensor Networks

Abstract

Efficient data collection is the core concept of implementing Industry4.0 on IoT platforms. This requires energy aware communication protocols for Wireless Sensor Networks (WSNs) where different functions, like sensing and processing on the IoT nodes is supported only by local battery power. Thus, energy aware network protocols, such as routing, became one of the fundamental challenges in IoT data collection schemes. In our research, we have developed a novel routing algorithm which aims at increasing the lifetime of the IoT network subject to pre-defined reliability constraints. Assuming that the data is split and transmitted in the form of packets, we seek the optimal paths over which packets can reach the Base Station (BS) with effective energy usage subject to the condition that the probability of successful packet arrival to the BS exceeds a pre-defined threshold (reliability parameter). As far as the radio propagation is concerned we use Rayleigh-fading in our model. The new algorithm will guarantee an increased longevity and information throughput of the network due to the efficient energy balancing in the IoT network. The performance of the new protocol has also been studied and confirmed by simulations.
