Firefly Resources Optimization Technique for Data Delivery in Wireless Multimedia Sensor Networks

Wireless Multimedia Sensor Networks (WMSNs) isconsists of small embedded audio/video motes capable of extracting the surrounding environmental information, locally processing it and then wirelessly broadcasting it to sink/base station. Multimedia data such as image, audio and video is bigger in quantity than scalar data like temperature, pressure and humidity. Thus, to transmit multimedia information, more resources (i.e. energy, bandwidth, memory, buffer size and processing capability)are required. Recently, many research works has been developed for optimizing the resource constrained in WMSNs. But, WMSNs still needs a new resource optimization technique for effective multimedia data delivery with reduced resource utilization. In order to overcome such limitation, a novel Firefly Resource Optimized Data Delivery (FRODD) technique is proposed in this paper. FRODD technique is designed for efficient transmission of multimedia data with higher scalability and stable quality of service in WMSNs surveillance applications. In FRODD technique, Firefly Resource Optimization (FRO) algorithm is designed for exploring the optimized resource routing path and transmitting the incoming data streams according to their demand requirements. The main goal of proposed FRODD technique is to reduce resources utilization of sensor nodes while delivering multimedia data from the source node to destination in WMSNs. Experimental evaluation of FRODD technique is done with the performance metrics such as scalability, stability, accuracy of multimedia data content, energy utilization rate, bandwidth availability. Experimental analysis shows that the FRODD technique is able to improve the scalability rateby 18% and also reduce the energy utilization rateby 25% when compared to the state-of-the-art works.
