摘要：Wireless sensors networking is a promising technology for a wide range of useful applications in many areas including civilian and military areas. Thanks to the sensing capabilities of Wireless Sensor Networks (WSNs), they become a prominent choice for certain applications such as environmental monitoring. The distributed sensors collectively realize the evolution of physical and operational phenomenon and predict its effect on mission execution and then trigger control actions that perform high-level mission procedures. However, efficiency, reliability and performance are the main challenges in deploying and utilizing WSNs especially in harsh environments conditions. This paper studies, the event tracking issues and identifies the reasons behind the deficiency of reliable transfer of the data traffic under abnormal situations or scenarios where WSN characteristics and performance may differ significantly. It investigates the performance issues related to routing protocols in WSN such as Low-Energy Adaptation Clustering Hierarchy (LEACH) and Directed Diffusion by using a simulation model in which represents a variety of sensor networking environments and examine their suitability for the WSN environment in terms of data traffic control. It was found that LEACH routing protocol outperforms Directed Diffusion due to its hierarchical nature, but suffers from several issues such as scalability, adaptability, utilization, latency, and throughput.
