Wireless Multimedia Sensor Networks (WMSN) can handle different traffic classes of multimedia content (video, audio streams and still images) as well as scalar data over the network. Use of general and efficient routing protocols for WMSN is of crucial significance. Similar to other traditional networks, in WMSN a noticeable proportion of energy is consumed due to communications. Many routing protocols have been proposed for WMSN. The design of more efficient protocols in terms of energy awareness, video packet scheduling and QoS in terms of checkpoint arrangement still remains a challenge.
