In this paper, we analyze the capacity of Circuit Switched Voice over High Speed Packet Access (HSPA) (CSoHS), using a Release 7 HSPA system that supports Continuous Packet Connectivity (CPC). On the Downlink (DL), we modeled the power consumption of the Fractional Dedicated Physical Channel (F-DPCH) and the Enhanced DCH Hybrid ARQ Indicator Channel (E-HICH). On the uplink (UL), we modeled the overhead...
In a sensor network there are many paths between a source and a destination. An efficient method to explore and navigate in the `path space' can help many important routing primitives, in particular, multipath routing and resilient routing (when nodes or links can fail unexpectedly) as considered in this paper. Both problems are challenging for a general graph setting, especially if each node cannot...
Monitoring the health of a sensor network is important for maintaining the health and normal operation of the network. For large-scale cost- effective monitoring, using inexpensive motes as sniffers is an attractive choice. In this paper, we quantify the capability and fidelity of mote-class sniffers for sensor network monitoring. In particular, we experimentally quantify the sustainable workload...
According to loop characteristic of partially urban road network, urban loop-road traffic coordination control system based on the spit-layer parallel cusp catastrophe particle swarm optimization algorithm is proposed. In the system, the area control system is replaced by the loop-road line control system, and the control sub-area is closed loop-road in road network, a three-layer stepped distributed...
Wireless sensor networks have been used for many delay-sensitive applications, e.g., emergency response and plant automation. In such networks, delay measurement is important for a number of reasons, e.g., real-time control of the networked system, and abnormal delay detection. In this paper, we propose a measurement architecture using distributed air sniffers, which provides convenient delay measurement,...
Audio steganalysis has attracted more attentions recently. Echo steganalysis is one of the most challenging research fields. In this paper, an effective steganalysis method based on statistical moments of peak frequency is proposed. Combined with power cepstrum, it statistically analyzes the peak frequency using short window extracting, and then calculates the eight high order center moments of peak...

In this paper, an effective steganalysis method based on statistical moments of peak frequency is proposed. Combined with power cepstrum, it statistically analyzes the peak frequency using short window extracting, and then calculates the second order and third order center moments...
