Real-Time data packet scheduling in WSNs: An Overview

Limited computational resources in Wireless Sensor Networks (WSNs) considered a key challenge in sensor environment. With such constraints on the network topology, scheduling real-time and non-real-time data packet could not perform as expected as on other type of the wireless environment, eventually, could have an impact on the network performance in terms of power degradation and average latency. This paper presents the base packet scheduling structure alongside the classification of packet scheduling algorithms and examples of most well-known algorithms for each class of scheduling scheme. Additionally, the authors highlight some weak points in each presented example in order to give a deep understanding of packet scheduling classes and algorithms.
