Energy efficient design methodology using congestion control parameters in wireless networks [articol]

Abstract

Due to the rapid development of sensors in recent years, there has been a growing demand in wireless multimedia applications such as video surveillance, traffic monitoring and real time object tracking systems. So, there is a need to consider energy efficient design inorder to save power. The characteristics of WMSN lead to congestion occurrence that affects the performance of the network. To maintain the required QoS parameters for the specific applications, the factors that affect the performance of the network and its significance have to be identified. It is identified that, workload, traffic burstiness and routing protocol are considered to be the important factors which affect the important performance metrics video quality, reliability and latency. The important factors and their impact on the performance metrics are examined by design of experiments method. Based on the results, the network infra-structure requires very less consumption of power when transmitting data and also it improves quality of services (QoS).
