Aiming at the loss of angle information and detection accuracy of traditional radar system, the paper puts forward the Network Radar Countermeasure System active, passive and integrated anti-stealth detection model. The model, which is based on single-bistatic equivalent principle and simplification model of RCS, combines the advantages of bistatic radar, netted radar, MIMO radar, passive radar, etc...
Reducing interference to primary users while achieving high throughput for secondary user transmissions is a critical issue in an underlay cognitive radio network. In this paper, we explore the use of beamforming at secondary user transmitters. Two power allocation schemes, fixed transmit power allocation (FTPA) and adaptive transmit power allocation (ATPA) are investigated considering scenarios with/without...
Multi-robot manipulation allows for scalable environmental interaction, which is critical for multi-robot systems to have an impact on our world. A successful manipulation model requires cost-effective robots, robust hardware, and proper system feedback and control. This paper details key sensing and manipulator capabilities of the r-one robot. The r-one robot is an advanced, open source, low-cost...
This paper presents fundamental results for the problem of throughput optimization in heterogeneous mobile sensor networks by considering the penalty incurred when a mobile node switches to another receiver. We present online and offline algorithms determining which receiver each mobile node connects to at each time slot to maximize total throughput. We initially consider the network setup with a...
Due to high mobility, highly dynamic topology and unreliable communication medium, performing video multicast over a mobile ad hoc network (MANET) is a challenging task. In this paper, a robust multiple tree multicast routing (RMTMR) protocol for MANETs is proposed to ensure robust and efficient video multicast against high node mobility. RMTMR employ a practical stochastic upstream nodes assignment...
