Wireless Hotspots: Current Challenges and Future Directions For Next Generation Hotspot

In this work, we study the effects of hotspots in wireless cellular networks. In recent years, wireless Internet service providers (WISPs) have established Wi-Fi hotspots in increasing numbers at public venues, providing local coverage to users and empowering them with the ability to access email ,Web , and other Internet applications on the move. Wi-Fi hotspots are one of the most promising scenarios for mobile computing .In this paper, we observe that while the mobile computing landscape has changed both in terms of number and type of hotspot venues, there are several technological and deployment challenges remaining before hotspots can become an ubiquitous infrastructure. These challenges include authentication, security and coverage .Thereby introducing a new concept of NGH ,that would enable mobile subscriber or user to connect automatically and securely to hotspots ,hence providing a complete solution for Wi-Fi so as to enhance the performance and meet the upcoming demands of the market .
