REVERSE ROUTING HEADER (RRH): RRH [7] uses the mechanism of source routing technique to route the packets in optimal path for the nested mobile networks, while sending the packets from MNN to CN. The Mobile Router (MR) which is connected to MNN allocates 'n' number of RRH's to the previous Mobile Router (MR) along with the tunnel header.
The last Mobile Router (MR) inserts its home address in slot 1. The destination address of the outer IPv6 header is the HA of last Mobile Router (MR), and the source address is the care-of address of last MR. When the packet arrives at previous Mobile Router (MR) the Mobile Router (MR) swaps the source address with its care-of address, and records the original source address in next slot of the RRH it is similar for all Mobile Router (MR) that is connected in nested mobile network. The packet is then tunneled to the HA of 'n'th MR. Once 'n'th MR HA receives this packet, it notices the RRH and finds the packet being tunneled from the 'n'th MR. the HA then decapsulates and forwards the packet to CN [8].
The HA also creates a Binding Cache for 'n'th MR, including the entries recorded in the RRH and the source address of the outer IPv6 header. This Binding Cache allows packets to the MNN to be tunneled using the RRH for the opposite direction. The RRH protocol leaves the MNN and the CN untouched and only the intermediate MRs and the HA are required with the modification. RRH protocol offers the optimal route while achieving security equivalent to the NEMO Basic Support protocol.
RECURSIVE BINDING UPDATE (RBT) : Recursive Binding Update is helpful to utilize the binding information of the MR contained in the binding cache of the CN. When the CN wants to send a packet to the Visiting Mobile Node (V...

...sed to simulate both the scenarios. From the simulated scenario the output is recorded in a separate file with .tr extension. From the resultant file the total number of packets transferred, total number of packets dropped, packets source and destination node were predicted. The data is given in Table 1.
The following XGRAPH (Figure - 4) shows the Packet Loss during the packet transfer in the existing system. The total number of packet lost during packet transfer from correspondent node to the mobile network node is plotted in y axis and the time is plotted in x axis. The packets that are dropped are represented by dots. The dots are over crowded which depicts that the packet loss in the existing system is high. As the packet loss increases the quality of service decreases. Increased packet loss causes jitters and poor video display which is annoying for the user.
Localization-free routing protocols: the protocol does not require the full-dimensional location information, all it need is the depth information of each node. The most popular routing protocol in this class is Depth-Based Routing (DBR) [1] protocol. (section 4)
Routing scheme means to find a path from once place to another on which packets can travel. In most of the cases, we need multiple routers in order to route the packet to the destination. Routing contains three elements:
3) In the Drop_NoFast scenario, obtain the overlaid graph that compares Sent Segment Sequence Number with Received Segment ACK Number for Server_West. Explain the graph.
For the west subnet, one ethernet_server and one ethernet4_slip8_gtwy router are connected with a bidirectional 100 BaseT link. The attributes of the server are shown in the picture
Binding: In order to run the function the RPC must know what server to contact and where. If this changes for any reason, or there are multiple servers that could run the function it needs to know which one to use (Wills, 1998).
With an IPv4 network, all the work consisting of network renumbering and assigning of new address schemes would had been done manually. Another useful feature of IPv6 is the multi-homing technique. It allows simultaneous connections which are established to two ISPs. Compared to IPv4, IPv6 has a much simpler packet header structure, which is designed to minimize the time and efforts that go in to header processing. IPv6 offers better end-to-end connectivity than its predecessor IPv4. The most exciting applications to emerge in todays world is peer-to-peer applications such as multi-player online games, video-conferencing (streaming), file sharing and
As seen, I drew only Highway 99 and the two rivers as physical markings on the map. I did that to approximately orient the viewer and also show that even physical boundaries were not constant boundaries for the school lines. I did not draw out the roads on this map for two reasons. One: our school district covers a large amount of space and drawing the streets out would have made the boundary lines look very muddled and made it difficult to see any other markings on the map. Two: the streets did not make a significant difference in how the boundary lines were drawn if you look at the map logically. For example, the border between Davis and Gregori is drawn by streets, but it is not one singular street, they zigzag along several housing developments that are fairly new. None of them wanted to go to a “ghetto” high

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.

Transportation system is a dynamic system. Information about traffic must be regularly updated to keep pace with ever-changing transportation system. Data must be collected and analyzed systematically to get representative information.
G in 1G, 2G, 3G and 4G stands for the “Generation” of the mobile network. Today, mobile operators have started offering 4G services a higher number before the ‘G’ means more power to send out and receive more information and therefore the ability to achieve a higher efficiency through the wireless network. During the time of 1G, radio signals were transmitted in ‘Analogue’ form. 2G networks on the other hand, were based on narrow band digital networks. The 3rd generation of mobile networks has become popular and users access the Internet over devices like mobiles and tablets. This means a 3G network actually allows for more data transmission and therefore the network enables voice and video calling, file transmission, internet surfing, online TV, view high definition videos, play games and much more. 4th Generation mobile networks are believed to provide many value added features.
