High-efficiency video coding (HEVC) outperforms H.264 in coding efficiency. However, the rate–distortion optimization (RDO) process in coding tree unit (CTU) partitioning requires an exhaustive exploration of all possible quad-tree partitions, resu

High-efficiency video coding (HEVC/H.265) is one of the most widely used video coding standards. HEVC introduces a quad-tree coding unit (CU) partition structure to improve video compression efficiency. The determination of the optimal CU partition i

Among a series of video coding standards jointly developed by ITU-T, VCEG, and MPEG, high-efficiency video coding (HEVC) is one of the most widely used video coding standards today. Therefore, it is still necessary to further reduce the coding comple

Traditional distance-based location verification system (LVS) is ineffective for some attacks in sparse mobile ad hoc networks, e.g., the similar distance-based malicious (SDM) attack. In this letter, we propose to exploit radio irregularity to build

In this paper, we investigate the coverage optimization for LTE networks considering the network load. The network coverage is defined as the number of served users of evolved Node B (eNB) which is determined by eNBs' antenna tilt angles (ATA). The c

In wireless sensor networks, nodes are power-limited, hence, we need to save the energy of nodes to guarantee the operations of the network. In this paper, the energy consumption of nodes in the process of node location estimation is reduced by alloc
