Link Quality Based Opportunistic Routing Algorithm for QOS: Aware Wireless Sensor Networks Security

An energy-efficient routing is an essential task in a wireless sensor network topology. It provides a good cost metric encapsulating wireless link quality. Quality of service (QOS) based communication increases momentous challenges due to the growing real time applications need in wireless sensor networks (WSNs). In this paper, we propose a novel link quality based opportunistic routing method. Assessment of the link quality using link quality appraisal technique to identify and prevent the broadcast faults in the network. Opportunistic routing (OR) algorithm will select the relay nodes based on OR theory to enhance the lifetime of whole network and feasibly create the ideal transmission distance for energy saving. Finally, compare and estimate the performance of the proposed method in the working platform of Matlab simulation. Inspection of QoS is essential for improving the security measures availability, reliability and serviceability of the system within WSNs. Simulation results shows that our method achieves more energy savings, and higher packet delivery ratio.
