We combine a simple energy model of radio trans-ceivers with analysis of ad-hoc routing to optimize system performance. A simple example of a linear wireless ad hoc sensor network is used to deduce the relationship between traffic load and optimal radio range of topology management schemes. We find that half of the power can be saved if the radio range is(More)
With the amount of data increasing rapidly, how to improve the scalability of nonlinear clustering has become a very crucial and challenging problem. In this paper, we design an efficient parallel nonlinear clustering algorithm by using a four-stage MapReduce framework. In our approach, we need to compute two quantities based on distance matrices, which,(More)
