802.11-based wireless LANs (WLANs) have become an important communication infrastructure for today's pervasive computing applications. Nevertheless, WLAN users often experience various performance issues such as highly variable signal quality. To diagnose such transient service degradations and plan for future network upgrades, it is essential to closely(More)
Recent years have witnessed the wide adoption of the RFID technology in many important application domains including logistics, inventory, retailing, public transportation, and security. Though RFID tags (transponders) can be passive, the high power consumption of RFID readers (interrogators) has become a critical issue as handheld and mobile readers are(More)
Recent years have witnessed the deployments of wireless sensor networks for mission-critical applications such as battlefield monitoring and security surveillance. These applications often impose stringent Quality of Surveillance (QoSv) requirements including low false alarm rate and short detection delay. In practice, collaborative data fusion techniques(More)
With a bandwidth reservation mechanism, we propose that LTE can assist existing WiFi networks to improve the Quality of Experience (QoE) of wireless communication in enterprise and meanwhile increase the available spectrum. To address the associated network selection problem between WiFi and LTE, in this paper based on the 3GPP standard Access Network(More)
