Simulation is an important approach to evaluate protocols. Realistic simulations lead to accurate evaluations. However, most of evaluations in VANET recently were still using MANET mobility models or MANET models with a map bounder. Existing VANET mobility models, which treat all nodes identical, cannot reach most researchers' demand. In this paper, we(More)
Wireless Mesh Networks (WMN) is a new type of wireless access network that combines the advantages of Wireless Local Area Networks (WLAN) with those of Mobile Ad hoc networks (MANET). The localization of mobile nodes in WMN has not been paid much attention as of yet in comparison with that of WLAN and MANET. As an essential component of user mobility(More)
Due to the rapid increase of Android apps and their wide usage to handle personal data, a precise and large-scaling checker is in need to validate the apps' permission flow before they are listed on the market. Several tools have been proposed to detect sensitive data leaks in Android apps. But these tools are not applicable to large-scale analysis since(More)
Optical neural stimulation in the cochlea has been presented as an alternative technique to the electrical stimulation due to its potential in spatially selectivity enhancement. So far, few studies have selected the near-infrared (NIR) laser in cochlear neural stimulation and limited optical parameter space has been examined. This paper focused on(More)
Research on auditory neural triggering by optical stimulus has been developed as an emerging technique to elicit the auditory neural response, which may provide an alternative method to the cochlear implants. However, most previous studies have been focused on using longer-wavelength near-infrared (>1800 nm) laser. The effect comparison of different laser(More)
It is critical for a large telecommunications company such as Singtel to truly understand the behavior and preference of its customers, in order to win their loyalty in a highly fragmented and competitive market. In this paper we propose a novel graph edge-clustering algorithm (DGEC) that can discover unique behavioral groups, from rich usage data sets(More)
