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 Discovery and Selection Function (ANDSF) framework,...
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 monitor the performance of a WLAN and collect...
Site selection method determines the best server for a given client among multiple replicated servers deployed at geographically distributed locations. It is an important function of a global load balancing (GLB) system in application delivery controller (ADC) which is usually deployed at the entry of data centers. This paper presents a site selection method based on DNS Reply Race and Reflection...
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 increasingly available in pervasive computing...

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 that can deal with sensing uncertainty and...
