The Linux TCP/IP stack contributions have recently pointed all in the same direction: maximize available throughput while maintaining low latency. These activities started by mitigating buffebloat phenomenon at network bottleneck as much possible. So far, deployed solutions been designed considering standard models for that could be either wireless or wired. introduction of Wi-Fi 6 is dislocati...

Crowdsourced wireless community network enables individual users to share their private Wi-Fi access points (APs) with each other, hence can achieve a large Wi-Fi coverage with a small deployment cost via crowdsourcing. This paper presents a novel contract-based incentive framework to incentivize such a Wi-Fi network crowdsourcing under incomplete information (where each user has certain privat...

Wi-Fi is mission-critical in our personal and business lives. It’s in our homes, offices, hospitals, coffee shops, and on our flights. Great Wi-Fi is no longer a luxury—it’s a must have. Great Wi-Fi networks are stable, with high capacity and performance, that exceed our quality of experience (QoE) needs. However, most Wi-Fi networks today are only qualified for coverage, with basic element and...

Due to the fast increase of mobile traffic, most mobile network operators face the congestion issue in licensed spectrum bands. Several telecommunication vendors and operators propose to expand LTE service to the unlicensed spectrum bands to relieve the traffic congestion. However, LTE in unlicensed spectrum may interfere with Wi-Fi communications in the same bands and cause significant decreas...

Android devices are portable, equipped with powerful processors, and can act as both mesh routers and clients through Wi-Fi Direct, making them a suitable platform from which to deploy a wireless mesh network. To allow Android devices to automatically establish and participate in a wireless mesh network, we circumvent two key problems of the Android’s Wi-Fi APIs: lack of direct support for ad-h...

Cities around the world are currently considering building expensive Wi-Fi infrastructure. In urban areas, resident operated Wi-Fi access points (APs) are dense enough to achieve ubiquitous Internet access, provided we can induce the hosts to provide guest Wi-Fi access. However, sharing Wi-Fi involves taking on responsibility for the guest’s actions. Our main contribution is a novel mechanism t...

This paper presents a dominant channel occupancy (DCO) mechanism for the Wi-Fi backscatter uplink in the industrial Internet of things (IIoT). The DCO provides high-priority channel access and reliable burst transmission to the Wi-Fi backscatter devices, thereby enabling the Wi-Fi backscatter tag to deliver its tag information to the Wi-Fi reader without interference from neighboring legacy Wi-...
