A cross-layer-based routing with QoS-aware scheduling for wireless sensor networks

Due to the increased use of sensor nodes in a variety of application fields, wireless sensor networks need to handle heterogeneous traffic with diverse priorities to achieve the required quality of service. In this paper, we address the cross layer quality of service-aware scheduling for wireless sensor network with respect to delay and reliability in an energy efficient way. A node disjoint multipath routing is used and a QoS-aware priority scheduling considering MAC layer is proposed to ensure that real time and non-real time traffic achieve their desired QoS while alleviating congestion in the network. We evaluate our algorithm with extensive simulations and the results have demonstrated the effectiveness of our proposed scheme for different metrics.
