Nowadays MANETs have obtained a sensible interest due to the growing number of wireless device users. Hence, Mobile Ad-Hoc Networks are used in real time applications, and these real time programs need QoS assurance in terms of throughput and delay. Hence, it assets the QoS in MANETs. The main problem is the communication which is more a shared standard in a particular channel. In this work, the authors suggest an Achievable Throughput based Admission Control Protocol (ATACP) for controlling a channel from becoming overloaded, thereby making sure an assured throughput for real time traffic. Achievable Throughput based Admission Control Protocol works on a cross layer structural design that encompass the network and the MAC Layer and the admission control is carried in each node during the path discovery. The node broadcasts the route request to its neighbors providing its achievable throughput that satisfies the desired throughput considering the contention count. The performance of the ACP maintains the ineffective overhead throughput and End-to-End Delay MANETs. This work proposes the improving routing mechanism in MANETs using discovery routing protocols to achieve the effectiveness of throughput and less end-to-end delay over Mobile Ad-hoc Network.
In this paper, the authors have devised a new robust beam forming algorithm called Variable Step Size Normalized Least Mean Square (VSSNLMS) for smart antenna systems. Firstly, the performance of Least Mean Square (LMS) and Normalized Least Mean Square (NLMS) algorithms are analyzed with respect to the convergence speed and interference suppression capability. It is found that, both the methods use fixed step size. As a result of this, they show low convergence rate. Hence these algorithms cannot track the desired signal properly in an environment, where the signal characteristics are changing rapidly. The proposed VSSNLMS algorithm uses a variable step size. This improves the convergence rate and produces deep nulls in the direction of interferences which improves the interference suppression. Hence the proposed method is robust and better than the normal LMS and NLMS algorithms and can be used effectively in advanced mobile communication applications.
Mobile Adhoc Networks have become a part and parcel of technology advancements due to its extraordinary technique. Open communication feature make it prone for various security threats. Subsequently, there are many security threats like DDOS, Wormhole, Black hole etc., which not only affect the network performance but also responsible for the leakage of sensitivity of information. Jelly-Fish attack is one of the routing disruption attack which lies in the series of wormhole and black hole attack at network layer. It attempts to compromise the network packet and store them for a period of time. It may try to introduce delay or partial capturing of packets during communication. Due to big impact of jellyfish attack, it has gained a big name in recently and most wide area for researchers. Jellyfish Attack exploits the end-to-end communication and creates congestion in transmission protocols. Arbitrary network failure or node failure is the natural phenomena and may vary as per real life deployment, but intentional failure or compromising network may lead to information leakage. Security in mobile networks is a challenging task. The complete study observes that the security threats not only capture the packets but also degrades the network performance. To overcome vulnerability problems, this work considers jellyfish attack as the study target and will derive a mechanism to identify and prevent mobile networks from security threats.
Many QoS provisioning solutions were described in the past, but none of them are tested on video traffic and also the effects of mobility and dissimilarity in link quality are not labeled properly. The proposed efficient QoS-Aware Routing Protocol (QARP) that uses Cross-Layer Communication (CLC) and Session Admission Control (SAC) methods to provide QoS is guaranteed in terms of network bandwidth. The QARP performs QoS-aware route discovery by considering the effects of both inter-contention, and intra-contention in the route discovery phase. Only data sessions are considered for which a route with needed bandwidth is found that is admitted into the network by SAC process [14]. The highly varying characteristics of transmitting video data checks the SAC process less reliable due to the unavailability of accurate session bandwidth consumption information. The increase is possibility of wrong admission not only degrades the video quality of admission flows but also affects the quality existing data sessions. In future the service experience of an end user can be used for adoption streaming procedure and presentation assessment of the developing approach in terms of Quality of Experience.
Multi-hop Cellular Networks (MCNs) use different multiple low power transmitters for high throughput and coverage of large area in a cellular network. A quantitative study on resource allocation schemes by jointly considering Interference Coordination (IC) and Load Balancing (LB) in MCNs improves throughput and large coverage. But still it suffers from load unbalance and Inter-Cell Interference (ICI) problems. In this paper, these problems are tackled by jointly considering a novel Mobility Load Balancing (MLB) and Inter-cell Interference Coordination (ICIC) algorithm in MCNs. This algorithm is simulated under fractional Frequency Reuse (FFR), Soft Frequency Reuse (SFR), Reuse-1 and Reuse-3 frequency planning schemes. The simulation is performed with Round-robin, Proportional fair and Best-channel quality indicator (CQI) schedulers. This shows that the proposed algorithm provides significant improvements in the Quality of Service (QoS) provision, cell-edge spectral efficiency and the number of unsatisfied users. The main objective of this paper is to provide higher data rates, improvement in cell-edge spectral efficiency, and reduce the unsatisfied users' in the future wireless cellular networks.
