There are many types of data co-existing in wireless multimedia sensor networks, which have different quality of service requirements. So quality of service is an important issue of wireless multimedia sensor networks. This paper proposes an angle-based differentiated services routing algorithm. Nodes in this new algorithm select appropriate transmitting region which is classified by its deviate angel for different types of date streams, and choose the appropriate route based on local neighbor information such as neighboring node position, single-hop communication cost and residual energy. The simulation results showed that the proposed algorithm outperforms some well-known routing algorithms in terms of multimedia data stream delay, jitter, packet loss rate and power consumption.
