Abstract: Most of the energy-aware routing protocols used for routing in Wireless Multimedia Sensor Networks (WMSN) employ shortest path routing for efficient transmission of data.The increasing availability of low cost wireless sensor devices enable audio, video and text data being sensed and transmitted through wireless network.However, Wireless Multimedia Sensor Networks (WMSN) requires a new routing algorithm for effective multimedia transmission. In this study we plan to develop a Resource Optimized Spectral Route Selection (RO-SRS) technique for efficient transmission of multimedia content with high and stable quality of service in WMSN surveillance applications. Spectral route selection strategy is designed by aggregating the sensed multimedia data content with similar size and same destination sink into different groups. The possible routes between the sensed multimedia content sensors to respective sink are selected from the wireless sensor communication. This point allowsmore links to be available for RO-SRS to explore more routingpaths and enables RO-SRS to be different from existing route selection technique. With possible routes, spectrum of routes is identified for efficient transmission with high throughput, minimal data loss and delay. Simulation comparison in this paper indicates that RO-SRS is highly suitable for multimedia transmission in WMSNs.
