In this paper, the make-before-break handover method is basically considered in order to reduce the SIP (session initiation protocol) session restoration delay due to the interface switching during WiFi-to-3G vertical handover under IMS (IP multimedia subsystem). Actually, the session restoration delay in WiFi-to-3G handover scenario can be dramatically reduced by performing IMS registration an...

The needs for bridging of digital divide in rural communities and the economics of currently available broadband access technologies motivate for innovate and deploy new system designs and applications. The widely available and flexible WiFi technique meets the cost and suitability targets for rural broadband applications. To cope with the special requirements of rural communication, amendments...

The lighting industry has been comprehensively developed and deployed during recent decades, especially with the rise of LED technology. As a related technique field, lighting control system has also draw more and more attention; therefore intelligent lighting control systems are needed. Nowadays, several famous lighting companies are working on a next generation of lighting control system, whi...

Underwater Internet-of-Things (UIoT) is an extension of technology in underwater. The underwater acoustic network with WiFi architecture (UW-WiFi), as a specific deployment UIoT, has been proved to be promising technique for wide-ranging marine applications. However, due the unique features channel, such long and variable propagation delay, low available bandwidth high bit error rate, conventio...

This paper investigates a new class of carrier-sense multiple access (CSMA) protocols that employ deep reinforcement learning (DRL) techniques, referred to as deep-reinforcement (CS-DLMA). The goal CS-DLMA is enable efficient and equitable spectrum sharing among group co-located heterogeneous wireless networks. Existing CSMA protocols, such the medium control (MAC) protocol WiFi, are designed f...

This paper presents an integrated view of cognitive radio technologies for efficient wireless services in dense spectrum environments. The rationale for cognitive radio based systems is discussed, leading to an identification of the available design space that ranges from reactive interference avoidance to spectrum etiquette and eventually network collaboration. After reviewing prior work in th...

This work describes a clean-slate inter-domain routing protocol designed to meet the needs of the future mobile Internet. In particular, we describe the edge-aware inter-domain routing (EIR) protocol which provides new abstractions, such as aggregated-nodes (aNodes) and virtual-links (vLinks) for expressing network topologies and edge network properties necessary to address mobility related rou...

With the rising industrial interest in cyber-physical systems (CPSs), there has been growing concern in the application of real-time wireless technologies to CPS applications. We proposed in previous work the RT-WiFi protocol that provides realtime high-speed predictable data delivery and enables designs to meet time-critical industrial needs. However, without explicit reliability enforcement m...
