We consider heterogeneous network (HetNet) systems comprising of two different types of base-stations (BSs): macro and small BSs. In the previous studies for HetNet, it is observed that the distribution of signal to interference plus noise ratio (SINR) is independent of the BS density. This implies that network throughput increases linearly with the number of BSs. In this paper, however, we have identified...
In embedded smart devices, efficient memory management is critical because they have relatively small main memory to reduce cost and power consumption. Though Input Output Memory Management Unit (IOMMU), which is recently adopted on embedded smart devices, gives more free spaces in system memory, it increases memory allocation time when memory space is highly fragmented. In this paper, we propose...
