If the mobile node moves out of its home network, it starts searching a new router called access router to provide service from the visited network. With the help of AR the mobile node will maintain connectivity with its home agent. But if the mobile node joins with a new network, topologically it’s not possible to maintain the address assigned by the home network. So a new address called Care of Address will be assigned by the AR, then the mobile node has to send an update to its home agent about its new care of address. The process of updating new care of address to the respective home agent or correspondent node is called as Binding Update (BU). This process is implemented once again if the mobile node performs hand off. The mobile nodes duty is to update the new binding always to home agent; it ensures the message integrity between these nodes and assures the home agent about the legitimate mobile node. Binding Acknowledgement (BA) message will be a reply from home agent for the update.
An attacker may claim spoofed information that a particular legitimate mobile node is in different location than where it really is. If home agent believes that information and works based on it, then the respective mobile node may not get the traffic at all. A malicious mobile node may use the home address of a victim legitimate node in forged binding update sent to a correspondent node. These kinds of attacks generate the threats against the confidentiality, integrity and availability of the mobile nodes. An attacker may go through the contents of a packet destined to another node by redirecting the traffic to it. This leads to man in middle attack between mobile node and the correspondent node. An attacker may also send forged binding up...

The use of Return Routability procedure provides good support to MIPv6 without any security issues. This procedure verifies the message exchange between the home agent and mobile node’s care of address to ensure if both the nodes are reachable. The Binding Update messages are exchanged cryptographically. When symmetric attack is used always the response is sent to the node from where the request has come, which avoids the reflection attack. The correspondent node must wait for authorized binding update form the mobile node. The encapsulation (tunnel) also carried out through encryption between home agent and mobile node with IPSec ESP. Nonse exchange through tunnel avoids the possibility of attackers to verify the nonse message, hence the attack from the visited network can also be prevented.

(EAP Protocol forces mutual authentication, therefore the subscriber station would send an authentication message to the rogue base station. This does not completely alleviate the threat of rogue base stations, but it does make it more difficult.)
Network Security is the protection of the computer’s network though out the entire infrastructure. It can protect very important information and computer files to help prevent theft, spyware, malware, viruses, and more. Depending on if you have a public or private network, can determine what type of security settings you need for your network. All people are different on what they want to have secured or not, but most people do not know how to prevent people or things from getting in their network. “You must have a general understanding of security terminology and specifications as it relates to configuring hardware and software systems.”(Roberts, Richard M. 599). That quote states that by knowing and understanding security terms and specifics, you can
The mobile network is less secure because the user’s location can be monitored easily with gps and all their information can be accessed with little effort. With all this information easily accessible it puts a lot of people’s information at risk. In many apps and

IPv6 has no fixed compatibility with IPv4. Therefore, from the beginning of the introducing IPv6, several transition techniques have been provided, The IPv6 transition mechanisms are a set of rules applied in hosts and routers, with some effective strategies for addressing and deployment, which are designed to transmit from IPv4 to IPv6 or vice versa with the least interferences. But some of these techniques had not been accepted by internet technical community due to the lack of adequate technical reliabilities. The most successful and widely used transition methods probably are Dual stack, Tunneling and Translation techniques. In the Dual stack technique, both IPv4 and IPv6 can perform concurrently on the same foundation. However, they both can use the same router but not all of the IPV4 policies are supported by IPv6 and in these cases other techniques can be used (Jayasekara et al, 2012). One of these techniques is tunneling, in this method IPv6 packets will be encapsulated in IPv4 packets to transfer across an IPv4 infrastructure. Furthermore, it can be said that several different tunneling technologies have been developed to enable IPv6 connectivity across an IPv4 network and vice versa, generally they have been classified as configured or automatic (Rooney, 2011)In automatic tunnels no pre-configuration is needed and the destination address will be calculated automatically from the IPv6 next-hop address of the IPv6 route, while in configured techniques the end-point hosts will require to configure their IPv4 addresses before the communications through some other techniques such as DHCP, manual configuration...etc. (Loshin, 1999). Another popular technique is translation, in this approach a special method will be provided to...
There are some problems with different IPSec implementations that do not follow the standard and communicate properly between each other
Slaves need not be connected permanently to receive updates from the master. The slaves don 't need to be connected all the time to receive the updates from the master. That is mean the updates can happen through communications of long-distance, even through intermittent or temporary connections like dial-up
Robust Vehicular Routing Protocol (ROVER) [9] is geographical multicast protocol. In ROVER, control packets are using broadcasting and data packets are using unicasting mechanism. The main goal of this protocol is to broadcast a message to all presented vehicles in the specified zone of relevance (ZOR). ZOR can be designate as a rectangle specified by its corner coordinates. In this, a message can be described by using three terms called triplet (application, message, ZOR). If the vehicle within its ZOR and received a message then it accepts that message.

A Wireless Sensor Network (WSN) consists of hundreds and thousands of the sensor nodes. The sensors either communicate directly to an external base station (BS) or among each other. Larger the number of sensors deployed to sense a large geographical area, greater is its accuracy. Figure 1 shows the components of sensor nodes in its sch...
