Wireless multimedia sensor networks have attracted a lot of attention in the research and industrial community due to their influence and importance in scientific research and also their various applications. These networks are a special form of wireless sensor networks in which multimedia data such as video, image and sound are produced and transmitted by multimedia nodes. In many applications, multimedia data must be provided with predefined levels of quality of service. For example, real-time data transfer is essential for providing sensed data to the sink in these applications. Designing the routing protocol according to the requirements of the desired quality of service is always one of the most basic steps in the process of sending data packets. Therefore, in wireless multimedia sensor networks, special and different routing protocols are needed from those used in conventional sensor networks. In this article, a protocol is proposed for routing in multimedia wireless sensor networks by creating cooperation between scalar and multimedia nodes. In the proposed method, suitable criteria for multimedia applications are considered to select route nodes, and the decision to find the best neighbor in a system is made by applying those criteria in fuzzy logic system. The evaluations performed on the proposed method from the viewpoints of delay and energy consumption indicate its superiority over the previous methods.
