Topic : 
	Current Challenges and Future Directions For Wireless HotSpots.
	
Major Goals:
	1. Technological Challenges in Wireless LANS.
	2. Wireless Hop Security.
	3. Network Performance and Quality Of Service.
	4. Wireless Network Management.
	5. InterOperation With WAN Data Services.
	
Scope:  
	Wireless Internet service providers (WISPs), in recent years have established Wi-Fi hotspots in increasing 
	numbers at public venues, providing local coverage to traveling users thereby providing them with the ability to
	access web, email and other internet applications on the move.
	
	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 to be taken care, before hotspots can become an 
	ubiquitous infrastructure. Authentication, security, coverage, management, location services, billing and 
	interoperability are such challenges.
	
	A short study will be made on multi-hop networks, whereby users who are in out of range can be allowed to 
	access points over on or more hops (through intermediate network nodes, or users). In this paper we also discuss 
	how interoperation between cellular and hotspot networks can be beneficial to both wireless carriers and hotspot 
	operators.
