Efficient Routing for Delay-energy Tradeoff in Event-based Wireless Sensor Networks

Abstract

Wireless sensor networks (WSNs) play a crucial role in the Internet of Things (IoT) by providing a foundation for collecting, transmitting and processing data from the physical world. Beyond the necessity of proposing solutions that are in line with the constrained resources of sensor nodes, particularly their limited energy capacity, the consideration of real-time data collection becomes essential. This is particularly vital due to the fact that many IoT applications require timely data collection. However, the need to establish energy-efficient routes contradicts the requirement to guarantee timely data collection. Hence, achieving an equilibrium and striking, subsequently, a trade-off between these two issued becomes imperative. To answer this question, a localized delay-bounded and energy-efficient routing protocol (abbreviated as LDER) is presented. It is based on another protocol, namely DEDA, aimed at achieving a higher energy conservation degree. To validate the efficacy of LDER, simulations were conducted using the J-sim simulator. The results demonstrate the ability of LDER to achieve the desired equilibrium and prove its superiority over DEDA.
