Analysis of Microstrip H-Shaped Patch Antenna as a Moisture Sensor
Abstract: There are certain advantages of microstrip patch antenna having low cost, low profile antenna. But inspite of that there are certain disadvantages also like low bandwidth, low efficiency, complexity. This paper introduces the potential of the H-shaped microstrip antenna using DGS multiband as a microstrip sensor for bandwidth improvement and developed a relationship between return loss and frequency. This is simulated at CST software and the result was measured on …

Fuzzy Based Opportunistic Power Control Strategy for Cognitive Radio with Compressive Sensing
Abstract: Cognitive radio is an intelligent communication technology that allows secondary users to utilize licensed band opportunistically and helps in resolving the issue of spectrum scarcity. In spectrum sharing network, where the secondary user can communicate simultaneously along with primary user in the same frequency band, the main challenge to opportunistic radio spectrum access lies in finding balance between two conflicting goalsof satisfying performance requirements while minimizing interference. In this paper,the …

Study of MIMO-OFDM System for Time/Frequency Selective Fading Channel
Abstract: Future-generation wireless communication system requires higher performance system in terms of high data rate with better link reliability in hostile fading environment. Orthogonal frequency division multiplexing (OFDM) and multiple-input multiple-output (MIMO) antenna systems are a popular technique for transmission of signals over wireless channels. They individually assist multipath fading environment and improve link reliability without sacrificing much bandwidth and also provide high data rate. The combination of OFDM and MIMO …

A Constrained Strategy to Extend the Lifetime of Sensor Nodes for LoS Optimization in Wireless Sensor Networks
Abstract: Wireless sensor network is a group of wireless sensor nodes, each capable of sensing, processing and communicating, however, once deployed in numbers, form a network which cooperatively monitor the state of the physical world. The sensor nodes in the network have small batteries and cannot be replaced once exhausted. Due to this, the operational lifetime of sensor nodes is crucial in a variety of monitoring applications, since the number of …
