- Abstract
- Recently, wireless sensor networks have been researched as core technologies for ubiquitous computing. In wireless sensor networks, a sensor node has typically small amount of memory, a processor with low computing power, and wireless interface of low bandwidth. Many sensor nodes should be placed to gather information in a large area because of small sensing range of the sensor nodes and limitation of wireless communications. In this paper, the cluster structure is used to organize large-scale sensor networks. Here, we propose a delay reduction scheme based on network coding for voice traffic by coping with the congestion problem in large-scale sensor networks. Finally, the simulation results show that the proposed scheme can reduce the transmission delay significantly.
