—In the recent past, there has been a tremendous increase in the popularity of VoIP services as a result of huge growth in broadband access. The same voice-over-Internet protocol (VoIP) service poses new challenges when deployed over a wireless mesh network, while enabling users to make voice calls using WiFi phones. Packet losses and delay due to(More)
In this paper, we propose novel resampling algorithms with architectures for efficient distributed implementation of particle filters. The proposed algorithms improve the scalability of the filter architectures affected by the resampling process. Problems in the particle filter implementation due to resampling are described, and appropriate modifications of(More)
Newly developed resampling algorithms for particle filters suitable for real-time implementation are described and their analysis is presented. The new algorithms reduce the complexity of both hardware and DSP realization through addressing common issues such as decreasing the number of operations and memory access. Moreover, the algorithms allow for use of(More)
As the multimedia applications such as Voice over IP (VoIP) and Audio/Visual (AV) streaming across the Internet emerge, many are working on the network architecture to extend such applications to the wireless networking domain. The emerging IEEE 802.11e Quality-of-Service (QoS)-enabled Wireless LAN (WLAN) is considered a strong candidate for the air(More)
Particle filtering is a statistical signal processing methodology that has recently gained popularity in solving several problems in signal processing and communications. Particle filters (PFs) have been shown to outperform traditional filters in important practical scenarios. However their computational complexity and lack of dedicated hardware for(More)
This paper present an optimal camera placement method that analyzes a spatial-temporal model and calculates priorities of spaces using simulation of pedestrian movement. In order to cover the space efficiently, we accomplished an agent-based simulation based on classification of space and pattern analysis of moving people. We have developed an agent-based(More)
