Enhanced Routing Capabilities for WSN Using QOS Optimization Technique

Wireless Sensor Networks (WSN) have been implemented in a variety of applications ranging from environmental monitoring and control of industrial processes to healthcare and emergency response. In many cases, routing needs to meet stringent Quality of Service (QoS) requirements due to the time-sensitive nature of the data being transmitted. To address this challenge, several routing approaches have been proposed to enhance the performance of Delivery Ratio and Delay with QoS optimization. This paper presents an overview of different QoS-aware routing architectures and algorithms such as source-routing, hop-by-hop routing, location-aided routing, and random routing, which have been successfully applied to WSNs. We also discuss several QoS metrics such as throughput, delay, and reliability, as well as methods for their optimization. Finally, we provide some examples of current and potential applications where these approaches can be implemented. We conclude by discussing a few open research problems and future research directions in the area of QoS-aware routing for WSNs.
