Modern network sensors can gather multimedia data as well as scalar data. And these sensors compose WMSN. Wireless multimedia sensor network is sensitive to latency. Also, it transfers mass multimedia data of various forms. This thesis proposes a routing technique based on traffic priority in order to improve the multimedia data transfer by minimizing latency. In addition, it proposes a congestion control mechanism that uses packet service time, packet inter-arrival time, buffer usage, etc. In this thesis, we verified the reduction of packet latency by the priority of a packet as a consequence of performance analysis through simulation method. Also, we confirmed that the proposed mechanism maintained a reliable network state by preventing packet loss due to network overload.
