Subjective Analysis of Multimedia Traffic in Wireless Multimedia Sensor Networks

Abstract

Topical advances in Wireless Sensor Networks (WSN) have directed to the consequent generation of networks that let repossessing video, audio and data from the corporal surroundings called Wireless Multimedia Sensor Networks (WMSN) will facilitate novel claims such as multimedia observation sensor networks, environmental and structural screening, etc. Most of these applications entail means to bring multimedia content with not only an echelon of Quality of Service (QoS) but also Quality of Experience (QoE) metrices like, PSNR, SSIM, MOS, etc. Provisioning ample throughput, crouch delay and stumpy packet trouncing rate, while deeming network lifetime are the main QoS prerequisites of multimedia data transmission over WMSN. These setbacks impose us to exploit multipath routing that can afford soaring end-to-end bandwidth while providing high resiliency against the channel and clogging error for video transmission in WMSNs. To sustain a reliable QoE, Hexanode Realtime Power aware Routing protocol (RPAR) with cross layering has been proposed and hole bypassing also been introduced and tested by means of sending multimedia data like, audio, video and data signals and proved to be better while compared with the performance over Pre emptive AODV (PAODV) and Pre emptive DSR (PDSR) protocols.
