Abstract: Wireless multimedia sensor networks (WMSNs) are an emerging technology which employs some nodes endowed with a CMOS camera and/or a microphone for a series of innovative multimedia sensing applications. Typically, congested nodes may deplete the energy of the active congested paths toward the sink and incur in undesired communication delay and packet dropping, while bit errors during transmission may negatively impact the end-to-end quality of the received media. Congestion control and loss recovery mechanisms are expected from transport protocols, which usually provide one or both of these services exploiting different approaches. Due to the unique characteristics of multimedia-based wireless sensor networks, especially high bandwidth, low delay and reduced energy consumption requirements, communication protocols from traditional scalar wireless sensor networks are not suitable for WMSNs, which have demanded some research effort in adapting existing protocols or p!
roposing new protocols from scratch. We survey the state of the art of WMSNs transport protocols, addressing the recent developments and proposed strategies for congestion control and error recovery. Future research directions are also discussed, outlining the remaining challenges and promising investigation areas.
