Abstract

Conformal antennas are widely used in many applications for its characteristics of high radiation efficiency, high gain, reduced size and wider bandwidth. In this paper, the conformal antenna is used for its portability and light weight for public safety communications. The antenna is designed for the wearable purpose. The conformal antenna is designed and simulated using CST Microwave Studio. Textile technology is chosen for the fabrication of designed antenna. FR-4 substrate will be used as a dielectric. The simulated results are in synchronous with the target parameters. The size of the antenna is made compact and flexible. Dimension and total thickness of the antenna is given as 14.59 X 18.79 mm and 0.8 mm. The resonant frequency is achieved at 5.65 GHz and the effective bandwidth for these results is 4.5 GHz to 6 GHz with better return loss below -16 dB, achieved from the simulation. The value of reflection coefficient is obtained as 12.46 dB.

Prevention and Detection of Spoofing Attack in Wireless Sensor Network

Abstract

Wireless spoofing attacks are easy to work with and play an important role in the performance of a wireless sensor network. Even if a node's identity can be verified using cryptographic authentication, traditional security approaches are not always desirable due to their ground requirements. Challenging tasks in wireless sensor networks are to detect spoofing attacks, and determine the number of views to attack it, localization of multiple adversaries and eliminating them. The clustering approach is used to identify the spoofing attackers and localize them. But this approach has less accuracy in predicting the attackers. The proposed Intrusion Detection System (IDS) to detect the spoofing attackers helps in solving this problem. The cluster head act, related to IDS, is necessary to monitor the behaviour of nodes in the cluster. For example packet transmission makes it possible to determine the misbehaving nodes of the wireless sensor network. The simulation result clearly shows that the proposed scheme detects the spoofing attackers in Wireless Sensor Network efficiently and robustly. In this, the clusters are formed dynamically and periodically. A digital signature based on a specific protocol must be provided to ensure reliability and reliable data transmission for clustered wireless sensor networks. This paper includes the feasibility of the protocol in terms of security and safety during various attacks, as well as problems to solve the orphan node. The results obtained show that the proposed protocol has a better performance than existing secure protocols for a clustered wireless sensor network in terms of surface, security, and power consumption.

Abstract

The Channel Estimation (CE) is carried at the Base Station (BS) based on Up Link(UL) pilot transmission. In this paper the Minimum Mean Square Error (MMSE) estimator is analyzed. This work is to understand channel correlation spatially and how the Pilot Contamination (PC) affects its performance. The CE is described by the estimation of the channel response that has a unique pilot sequence. A Cellular Network (CN) that achieves maximum energy efficiency has been defined. In massive network, Spectrum Efficiency (SE) and Energy Efficiency (EE) are analyzed. Massive MIMO antenna allows more antennas to increase the EE and throughput.

Abstract

Wireless Sensor Networks (WSNs) have tight energy constraints than MANET because of limited energy capacity. So the design principles of conventional networks are not appropriate for WSNs. It needs innovative perspective to arrive at solutions for its own kind of problems. Hierarchical architecture based on clustering suits well due to the uniqueness of WSNs. Even though clustering involves some overhead, its effect on the behavior of WSN is tremendous. In this paper, a new Hybrid Layering with Selective Cluster Rotation (HUCSR) protocol for the energy efficient operation of WSN has been designed. In this protocol, the cluster head rotation is done selectively. Instead of rotating it in all clusters of the WSN scenario, rotation is done based on whether it has been actively participated in data handling. Simulation results show a slight increase in the lifetime of the WSN.

Abstract

In this work, an overview of design and challenges faced by RF engineers in the LTE/4G implementation from an RF system design perspective has been provided. LTE and LTE Advance form the next generation of the mobile communication standard in few countries. Although, LTE has already been implemented in various parts of the world, researchers are still coming up with new design challenges of such complex systems. Much focus has been thrown upon the antenna design aspect of the LTE/4G based systems. It has been noted that MIMO technology is best suited for the implementation of such robust technology, which aims in providing better channel utilization and reduced signal correlation between the adjacent channels present in the communication link. Further, a compact microstrip antenna operating at 2.4 GHz providing operation at 4G frequency band is presented. The presented antenna has good electrical and radiation characteristics for providing better services for 4G application.
