Reference-based fair MAC algorithm in Wi-Fi WLANs with capture effect

Enabling Fair Spectrum Sharing between Wi-Fi and LTE-Unlicensed

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...

Wi-Fi Based Positioning System

 Abstract—In today’s era position of any outdoor element can be determine precisely using GPS. But in the indoor environment like house, colleges, underground construction site GPS does not work well. As now-a-days all house and colleges are equipped with Wi-Fi access point, precise position can be found out using Wi-Fi using method name Received Signal Strength Indicator (RSSI). A series of e...

Refining Wi-fi Based Indoor Positioning

The increasing demand for location-based services inside buildings has made indoor positioning a significant research topic. This study deals with indoor positioning using the Wireless Ethernet IEEE 802.11 (Wi-Fi) standard that has a distinct advantage of low cost over other indoor wireless technologies. Most of the proposed Wi-Fi indoor positioning systems use either proximity detection via ra...
