This technology allows us to use wireless and still have some of the same protection as with a wired network. How Secure is it really? When a client communicates with an access point, this is when the network is most vulnerable to breaches in security. It is at this time that a hacker can access your network. Security issues are what continue to hold Wi-Fi technology back.

Introduction The growth of 802.11 networks has been met with the development of several wireless local area network (WLAN) discovery applications. These applications are designed to identify WLAN activity and network characteristics, providing enough information for an unauthorized user to gain access to the target network. For obvious reasons, WLAN administrators should be concerned about unauthorized access to their networks and therefore should attempt to identify the applications used to discover their networks. WLAN intrusion analysis is not entirely unlike traditional intrusion analysis; we are primarily concerned about the identification of traffic signatures or fingerprints that are unique to the applications we want to detect. Unlike traditional intrusion analysis however, we have additional challenges that are unique to wireless networks: 1.

Wireless LANs have gained popularity in areas such as the health-care, retail, manufacturing, warehousing and academia markets (Kurose, 2003). Some widely known wireless technology in use in devices includes, cameras, automobiles, security systems, and kitchen appliances. Wireless LANs use electro magnetic airwaves (radio or infrared) to transmit information from one point to another without relying on any physical connection (Dean, 2000). Radio waves often are referred to as radio carriers because they simply perform the function to delivering energy to a remote receiver. Networking firms have a range of technologies to choose from when constructing wireless LANs.

This survey aims to present the privacy preserving mechanisms employed in the Location based services. Moreover, the LPPMs are classified into cryptographic and non-cryptographic mechanisms, and taxonomy of the mechanisms is also discussed. Furthermore, the classification and comparison of different mechanisms are presented based on the probability distribution attack. Also the strengths and weakness of different mechanisms are highlighted. The development of new technologies has deeply influenced the traditional mobile networks which uses user location information for data transmission.

A huge number of mobile and embedded device interconnecting constantly by mobile and wireless networks with heterogeneous infrastructures , sharing serious and sensitive information, these ubiquitous computing environments ; however, may arise some security and privacy issues. Indeed, security is becoming increasingly a major issue in ubiquitous computing environments. This is because the big difference between traditional wired networks; and wireless, sensor and mobile ad hoc networks that are used in UbiCom environments. Therefore, ensuring that these networks, sensitive information and users are secure is a great obstacle , due to the unique features of these networks, such as: complexity, mobility, openness, scalability and dynamism (Boukerche and Ren, 2008). In addition, preserving data integrity, availability and confidentiality is also a mutual concern in UbiCom systems (Wang, McNair and Xie,2006) .

Solutions to the main challenges of mobile computing? Challenge 1 - Security and privacy threats of mobile computing One way to deal with the security and privacy challenges of mobile computing is for managers to formulate optimal policies regarding the use of mobile devices within an organi-zation. This method of dealing with security and privacy risks of mobile computing focuses mainly on the internal threats, originating from employees and other internal members of an organization. Harris et al. (2012) propose a model to identify the possible policy that an or-ganization should embrace with respect to mobile computing and the associated privacy and security threats.

The following is a case study about the Mobile Network Gives Haneda Airport Its Competitive Edge. It has components that describe about the WLAN components and the Role of WLAN at Airports WLAN (Wireless Local Area network) and its components: The task of developing a WLAN on commercial front possesses a greater challenge. Developing initial design, purchasing and installing components, managing and providing maintenance to the systems are the main basic parts of the WLAN. When we use WLAN on a commercial front then we may face the security and privacy concerns. The total area of that particular commercial area should be accessible.

It is an automatic-configured network of mobile devices which are connected by the wireless links. It is a new technique of wireless paradigm for the mobile hosts. These Ad Hoc networks are not like the traditional wireless networks that rely on a fixed infrastructure but these hosts are dependent on each other so that the network is connected always(Advanced Network Technologies Divisionn.d.). This represent a complex distribution system which have available wireless nodes of mobile that can self-organize into temporary and arbitrary topologies of Ad Hoc network freely and dynamically.It provides the users to use internetwork connection without any pre-required infrastructure. Hence we can see a Mobile Ad Hoc networks as an autonomous collection of all the mobile devices such as mobile phone, sensors, laptop etc.

The relationships between these topics will clarify and distinguish between the opposing sides of network neutrality. CONSUMERS The internet came to be because of the user. Without the user, there is no World Wide Web. It is a set of links and words all created by a group of users, a forum or a community (Weinberger 96). The consumer has been the ultimate decision maker in the proces... ... middle of paper ... ...Internet access into official regulation.

1. INTRODUCTION Nowadays for wireless networks, security represents a priority in order to assure protected communications. In IEEE 802.16, security has been considered as the main issue during the design of the protocol [1]. The Initial Network Entry procedure in an IEEE 802.16 (WiMAX) network has security defects which can be exploited by the Man-in-the-Middle (MITM) attack [2]. Improving network security in a live enterprise network with a large number of subscribers geographically dispersed should be done with minimum downtime, in order not to affect critical user data/voice services.
