A New Priority Concerned Distributed Channel Assignment Algorithm for Multi-hop Radio Networks

For multi-hop radio networks, traditional flat TDMA access method has the drawback of low wireless resource utility efficiency. To improve the slot reusability, spatial TDMA method can be adopted. In this paper, a new STDMA channel assignment algorithm is proposed which takes the service priority, node position and data status into concerned. In addition to limiting the information stored in and transferred among the nodes, it can balance the network throughput and improve the network performance. The algorithm is described in detail and its performance is investigated by simulations.
