The Imperative Study Onenergy Efficiency And Qos Aware Methods Survey In Wireless Multimedia Sensor Networks

Abstract

In later years, due to the fast Advancements in sensor technology and the availability of low cost hardware, the development of Wireless Multimedia Sensor Networks (WMSNs) has emerged. WMSNs are composed of resource constrained wireless nodes through which both the scalar data and multimedia data (i.e., audio, still images, and video) can be sensed and acquired from the environment. However, the resource constrained nature of multimedia sensing devices has made the WMSNs to face several challenges. To tackle these challenges, different authors developed different methods. In this paper, we have surveyed all such kind of methods. Initially we study about the basic architecture of multimedia senor node followed by characteristics and applications of WMSNs. Next, we have conducted a detailed survey over different methods and all those methods are segregated into three categories. Under the segregation, we have considered different aspects and segregated as Data Aware methods, QoS Aware methods, and Energy Aware methods. At the end, we also summarized the existing solutions and outlined several pros and cons.
