This study focuses on scheduling problem in Wireless sensor networks (WSNs) using dual heterogeneous radios. WSNs are widely used for environmental monitoring where nodes are deployed on a large area. Scalability is an important issue of wireless sensor networks. Thus, heterogeneous dual radio nodes are used where nodes are equipped with IEEE 802.15.4 and IEEE 802.11 radios for data reception from sensor nodes and transfer to the destination, respectively. Due to overlapping of their spectrum at 2.4 GHz ISM band, heavy interference is experienced. A collision free scheduling scheme is needed which also considers spatial distance between nodes in order to overcome interference. This study seeks and surveys methods on centralized and distributed scheduling of WSNs, heterogeneous WSNs especially TDMA and spatial TDMA scheduling mechanisms.
