Abstract— To provide high speed data traffic and maintain promised QoS in wireless systems IMS was introduced in 3rd generation networks. IMS uses SIP style session creation and maintaining means. As IMS deals with high rate data transfer so this module can be used for purposes other than catering QoS. Here we propose a technique in which IMS has been used for location update of any mobile node , it not only gives exact location of any randomly moving node but it also helps in emergency state where location determination of any node can be a setback. As a result real time position of any user equipment is obtained which can be further used by network operator or can be provided to use on his/her request in rescue cases.
Keywords— IMS, Location, Moving, Emergency
1. INTRODUCTION:
As cellular networks are being getting more advanced like 3G, 3.5G and upcoming 4G, user’s requirements regarding bandwidth, mobility and QoS provisioning are being increased. To cater for users QoS needs, a new module has been added in cellular systems i.e. IP Multimedia Subsystem (IMS). Managing QoS in networks is not new idea at all; in wired networks QoS has been maintained using Session Initiation Protocol (SIP) and the reason that this mechanism is being implemented in wireless networks is that so much of bandwidth was not available in cellular networks for user. But with the deployment of 3G and other new standards, higher data bandwidth is available .Now not only multimedia traffic is being routed using data standards but traditional voice traffic is also routed using Internet Protocol (IPS). [1] Discusses IMS in context of user requirements, enterprise requirements, operator requirements and regulatory requirements. It further highlights the...

... the session type being created. [3]
SIP is an application-layer management protocol that can generate, modify and terminate multimedia sessions. SIP can invite participants to sessions that already exist. Media can be removed from, or added to, a prevailing session. SIP supports the mapping of names and redirection services transparently. These services support personal mobility, hence the users can
uphold a single externally visible identifier regardless of their actual location in the network. [3]
The details of the session (e.g. the type of media) are not depicted using SIP. The body of a SIP message includes a description of the session, which is encoded in some other protocol format. One of such formats is SDP. This SDP message is conveyed by the SIP message in a manner which is analogous to a document attachment being conveyed by an email message. [3]
Cisco’s annual Internet Traffic Report (2013) shows that mobile traffic, perhaps the largest growing bucket of data in the world, continues to rocket upwards as people consume more video.
Last phase is data exchange. In data exchange, client and server exchanges the data by creating one or more data channels. In each channel, flow is control using window space available. There are 3 stages of the life of the channel: open channel, data transfer and close channel. One the channel is open by either of the party, data is transferred and then channel is closed by either of the party [3].

TOR (Roger Dingledine) is a circuit based low-latency anonymous communication service. TOR is now in its second generation and was developed from the Onion routing program. The routing system can run on several operating systems and protect the anonymity of the user. The latest TOR version supports perfect forward secrecy, congestion control, directory servers, integrity checking and configurable exit policies. Tor is essentially a distributed overlay network which works on the application layer of the TCP protocol. It essentially anonymizes all TCP-based applications like web-browsing, SSH, instant messaging. Using TOR can protect against common form of Internet surveillance known as “traffic analysis” (Electronic Frontier Foundation). Knowing the source and destination of your internet traffic allows others to track your behavior and interests. An IP packet has a header and a dat...
In using NAT, hosts on the Internet appear to be communicating directly with the NAT device rather than with the actual host inside the private network. Inbound packets are sent to the NAT device's IP address and the device changes the destination packet header from its own Internet address to the private network address of the true destination host. The result is that, in theory, a single globally unique IP address is used for hundreds, thousands, or even millions of privately addressed hosts. In practice, however, there are drawbacks. For one thing, many Internet protocols and applications depend on the network being truly end-to-end, with packets forwarded entirely unmodified from the source to the destination.

As we evolve in the information age, online privacy rights have grown over the past years. In 1986, a federal law was passed to protect an individual’s electronical information. “This law was produced to make a fair balance among the privacy expectations of citizens and the legitimate needs of law enforcement” (EPIC). With the Internet developing intensely, there is a great deal at stake such as the theft of your identification. But where it all begins is when you access the Internet. This is the first step in being aware of your privacy because you go through the process in signing up with an Internet Service Provider (ISP). With this process you have a IP address attached to your ISP. This is the primary step on how your information starts
The innovation in mobile phones has enormously changed the lives of the people all around the world. The proliferation of mobile phones spans across people of different age groups and leveraging the mobile phone for different usages. Over the years, the multi-functionalities of the mobile devices have diversified and intensified to become a comprehensive electronic device.
ABSTRACT : This paper describes the basic threats to the network security and the basic issues of interest in designing a secure network. it describes the important aspects of network security. A secure network is one which is free of unauthorized entries and hackers. INTRODUCTION

Internet Voice, also known as Voice over Internet Protocol (VoIP), is a technology that allows you to make regular telephone calls using a dial up or broadband internet connection instead of a regular phone line. Some services using VoIP may only allow you to call other people using the same service, bu...
Within a few years, there will be well over a billion mobile phone users worldwide and the majority of mobile phones will be connected to the Internet.
The TCP/IP is the most important internet operation protocol in the world. While IP protocol performs the mass of the functions which is needed for the internet to work. It does not have many capabilities which are essential and needed by applications. In TCP/IP model these tasks are performed by a pair of protocols that operate at the transport layer. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP). These two protocols are vital when it comes to delivering and managing the communication of numerous applications. To pass on data streams to the proper applications the Transport layer must identify the target application. First, to be able to attain this, Transport layer assigns an application an identifier. In the TCP/IP model call this identifier a port number. Every individual software process needing to access the network is assigned a un...
