Wireless Multimedia Sensor Networks (WMSNs) are a new and emerging type of sensor networks in which sensor nodes are equipped with cameras, microphones, and sensors producing both scalar and multimedia content. Multimedia data require un-interrupted data transmission, greater bandwidth, memory, power and low latency. Routing of data in a resource constrained network is a major issue in WMSNs. Paths in WSNs routing protocols are established based on min hops, max available power and low latency etc. In WMSNs, routing protocols are required to route large multimedia data as compared to scalar...
