“…The performance of mobile communication with antenna array depends on the DOA and angular spread. For the system of combining BF with STBC using single-array and multiple arrays was proposed in [8][9], where it assumed small number of transmit antenna. In this paper, an eigen-beamforming combined four branch STBC technique is proposed in massive MIMO systems.…”

An eigen-beamforming combined space-time block coding technique is proposed in massive MIMO systems. At the transmitter, utilize massive MIMO to form orthogonal beams, and then space-time block code is transmitted on these beams. At the receiver, space-time block code is decoded according to traditional decoding algorithm. The proposed technique can obtain diversity gain and beamforming gain simultaneously. Simulation results confirm the validity of the proposed technique.

“…The attack power of a Distributed DoS (DDoS) attack (Lau et al, 2000) is based on the massive number of attack sources instead of the vulnerabilities of one particular protocol. DDoS attacks, which aim at overwhelming a target server with an immense volume of useless traffic from distributed and coordinated attack sources, are a major threat to the stability of the Internet (Elnoubi et al, 2011). Distributed Denial of Service (DDoS) attacks pose an immense threat to the Internet and many defines mechanisms have been proposed to combat the problem.…”

The purpose of this study is to understand the flaws of existing solutions to combat the DDoS attack and a novel scheme is being provided with its validation to reduce the effect of DDoS attack in MANET Environment. As Internet users are increasing day by day, it is becoming more prone to attacks and new hacking techniques. People are accessing information and communicating with each other on the move. Mobile Ad-hoc Network (MANET) is responsible for this rapid change in the lives of people. With the emergence of technology, where people communicate or share important documentations on the go with the help of laptops, PDAs, notebooks, smart phones etc., the loopholes in the Internet security have also increased and they are becoming more difficult to handle due to the characteristics of MANET such as dynamic topologies, low battery life, multicast routing, frequency of updates or network overhead, scalability, mobile agent based routing and power aware routing, etc. The network is becoming more prone to attacks like DDoS, byzantine, resource consumption, blackhole, grayhole, etc. Therefore, there is an urgent need to look into the security issues to allow authorized users to access the information available on Internet without any risk. In this study, a novel scheme is proposed which deals with suppressing the influence of the attack. The effectiveness of the approach is validated with simulation in GloMoSim, integrated with parsec compiler, on a windows platform.
