The MANET is a network which can organize the mobile ad hoc network nodes dynamically with temporary and arbitrary topologies. This MANET offers many applications in current communication technology. The security and privacy in MANET is a major challenging issue as wireless communication is more vulnerable to security attacks. In this network the individual node operates like transmitter, receiver and router. Moreover, due to openness of the network, there are more chances for malicious users to enter into the network which creates an illusion. So that the individual node understands the data, even if it is sensed from original sender, malicious sender and receiver node behavior. Hence the malicious users create more data loss. So, these wormhole attacks creates network related issues and degrade the MANET efficiency. Major research is now concentrated on the behavior which makes the normal node to act as wormhole to degrade the network performance. In this paper, several parameters are studied and some parameters makes a node to become a wormhole. Experiments are conducted using popular network simulator – “Qualnet Simulator”. The results clearly show the impact of wormhole on the performance of MANETs.
In this paper, an attempt has been made to provide QoS in WiMAX IEEE 802.16 with fairness which is a challenging issue due to limited bandwidth and limited energy. To overcome these an attempt has been made in OPNET (Optimized Network Engineering Tool) which is a powerful network simulator. A appropriate classification approach in modern communication is on hand that is the usage of QoS managed via the community network operator. By developing a new System methodology to QoS with fairness by means of incorporating some principle concepts like UGS, ERTPS, RTPS, BE for VoIP, Video, HTTP to provide equal bandwidth allocation to all users in network. To get QoS along with fairness in WiMAX network, we need to overcome the issues like limited bandwidth and limited energy. This methodology proposes some other planning scheme mirroring the prerequisite of RTPS and the distinct NRTPS associations that accomplish the best ideal QoS requirement, excluding the immoderate aid consumption due to the fact that it maximizes delay for low-throughput applications as well as achieves low average, offers fairness regardless of version variation in server potential, and computationally efficient.
Particle Swarm Optimization (PSO) is a popular technique used to solve optimization problems in WSNs due to its simplicity, high quality of solution, fast convergence and insignificant computational burden. However, iterative nature of PSO can prohibit its use for high-speed real-time applications, especially if optimization needs to be carried out frequently. This paper outlines issues in WSNs, introduces PSO and discusses its suitability for WSN applications. It also presents a brief survey of how PSO is tailored to address these issues. The objective of this paper is to give a flavor of PSO to researchers in WSN, and to give a qualitative treatment of optimization problems in WSNs to PSO researchers in order to promote PSO in WSN applications.
The term block chain has been referred as the disruptive innovation in computing. The interest in blockchain technology has been growing since the idea developed in 2008. However, healthcare is one of the major applications in blockchain which has lots of concern over the data security. To make critical information secure the use of blockchain technology came up. Accordingly, more researchers along with the solution of blockchain technology in healthcare data defend the data from tampering and leakage. In this paper, we have done the simulation of processing time assessment of blockchain technology with various secure hash algorithms. This analysis provide better outlook to the user for using these new security framework in an constrained hardware environment.
A Wireless Sensor Network (WSN) is an aggregation of sensor nodes which are remotely deployed in large numbers and operate the environmental condition and have limited energy resource. In most of the hierarchical routing protocols, the cluster head (CH) selection is on the basis of random probability equation. There is a scope to reduce the energy dissipation by improving CH selection procedure. This research paper proposed a multi hop hierarchical routing protocol called Energy Efficient - Adaptive Periodic Threshold Sensitive Protocol (EE-APTSP), and makes use of evolutionary algorithm for improving cluster head selection of routing protocol in the sensor networks. The concept of relay node is introduced, which acts as an intermediary between Cluster Head (CH) and Base Station (BS) to ease the communication between the CH and BS. The simulation results obtained supports that our proposed algorithm is efficient in terms of network lifetime. APTSP based theory that can be used to create faster, smaller, and more energetic and efficient sensitive threshold. Network Simulator (NS2) is used to implement and test the proposed system. The proposed periodic sensitive protocol provides more energy with secured transmission, further it reduces routing overhead, improves packet delivery ratio and throughput.
