Handling the Energy-Delay Trade-off in Wireless Sensor Networks: State-of-the-Art

Abstract

WSN (wireless sensor network) is the most researched field these days which has finite advancements every year. It aggregates the MEMS (micro-electrical mechanical system) technology with wireless communication and digital electronics for sensor processing operations. WSN has many objectives such as enhanced network lifetime, energy utilization, reliability, stability, throughput, security, and less delay. But this paper considers the contradiction that the wireless sensor network faces in its own two objectives which are maximum energy utilization and less delay. There is always some trade-off between energy and delay parameters to achieve better results especially in the case of enhanced lifetime and time-critical applications. This paper provides the brief review of approaches taken by the researchers to achieve the balance between energy and delay parameters.
