This paper proposes a multipath routing algorithm using cross-layer architecture in wireless multimedia sensor networks (WMSNs) to provide QoS guaranteed delivery of data. When the algorithm proposed in this study establishes the path from source to destination node, it takes into account a distance to sink node, and energy level and link quality of neighbor nodes. It also specifies a service quality pattern and a service quality level depending on traffic pattern. By doing this, the proposed algorithm can realize a differentiated service with QoS guaranteed data transmission. This algorithm also enables to use multiple paths when delivering data. It helps to alleviate a power consumption concentration that happens at particular set of nodes along the frequently selected route. Concentrated power consumption can cause another problem, that is, route reconfiguration due to routing failure. The proposed algorithm effectively avoids the problem. As a result, the proposed algorithm can improve reliability of sensor network by increasing packet transmission rate and reducing packet loss rate and delay.
