Anycasting communication is a new “one-to-one-of-many” communication method in Internet Protocol version6 (IPv6) networks. With the help of this technology, it becomes a virtual watch to find the best server, which respond to a request of the client. Due to issues which are not resolved and very slow deployment of IPv6, anycast communication of network-layer is still not a reality. But in recent years so many researchers took their interest in the area of IPv6 anycast communication. It guarantees a look at the state and direction of the ideas in this area. In This paper we have discussed some of the major difficulties with network-layer anycast communication. We also focused on the possible solutions of the problems with IPv6 anycast communication, as well as some optimizations and applications that have been developed recently.

Flooding attacks are DDOS (Distributed denial of service) attacks and utilize the weakness of the network protocols. SYN flood exploits the 3-way handshaking of the TCP by sending many SYN request with IP spoofing technique to victim host and exhaust the backlog queue resource of the TCP and deny legitimate user to connect. Capturing the packet flow is very important to detecting the DOS attack. This paper present how the TCP SYN flood takes place and show the number of packets received by the victim server under the attack.

Splitting of traffic is typically proposed in order to increase the reliability of data transmission, to minimize the mean system delay and to provide load balancing. In this paper, we design for each path a queuing delay based traffic distribution scheme and implement a k-path routing that allows a given source node to send the data to a given destination node in a MANET. This approach of traffic distribution can increase the reliability of network system, provides the load balancing and minimization of system delay. The simulation results reveal that splitting of traffic approach perform better than the shortest path routing in terms of load balancing, reliability of network and in a minimum mean delay for the whole network

There are two main recursive algorithms for scan conversion of the circle on computer screen, the Bresenhams and the Midpoint circle generating algorithm both are pixel based; in this paper we are presenting a recursive new approach for scan conversion of the circle. The pixel in one octant has been determined with help of this algorithm and rest of the parts of the circle will be generated with help of symmetry.

These mobile nodes communicate with each other without any infrastructure. As wireless ad-hoc networks lack an infrastructure, they are exposed to a lot of attacks. One of these attacks is the Black Hole attack. In Black Hole attack, a malicious node falsely advertises shortest path to the destination node and absorbs all data packets in it. In this way, all packets in the network are dropped. In this paper, performance of AODV is evaluated in presence of black hole attack (malicious node) and without black hole attack with cbr traffic under different scalable network mobility. For this analysis RWP model is used.
