This paper presents an energy-efficient communication protocol which distributes a uniform energy load to the sensors in a wireless microsensor network. This protocol, called Distance-Based Segmentation (DBS), is a cluster-based protocol that divides the entire network into equal- area segments and applies different clustering policies to each segment to(More)
For a lot of speech enhancement methods it will be very helpful if we have some prior knowledge of noise or speech. It may make it possible to tune some parameters more precisely, so we can have better performance. One of the most popular and best known parameters is SNR or signal to noise ratio. In this paper a new method for SNR estimation in noisy speech(More)
