For Multiple Input Multiple Output (MIMO) systems, antenna selection is a must since the Radio Frequency (RF) chains connected with antennas consumes a lot of power. This paper studies the effect of antenna selection at transmitter side since the base station power consumption is around 60-80% of the entire wireless system. The TAS is performed by a simple(More)
Optimum deployment of Relay Station (RS) is considered as the most important issue especially for the users near cell boundary. The Multi hop Relay (MHR) network introduces the RS for the purpose of extended coverage and increased throughput. The main objective of this work is to provide a better Quality of Service (QoS) with a minimum deployment cost. In(More)
Deep web contents are approaches by queries presented to web databases and revisited data records are enwrapped in dynamically makes web pages (deep Web pages). The extracting information of data into deep web pages is inconvenient as underlying complicated structures of such pages. Existing work presented a vision-based approach to extract deep web data(More)
The recent development of mobile communications, has led to the increment of number of users that network operators need to serve. To cope with the increasing demand of users, the deployment of evolved node base stations (eNB) is an open issue in the present scenario. In our work, focus is on developing a cost-effective and power-efficient eNB deployment(More)
Femto cell networks are becoming very popular in indoor home and small business environments. Femto cells will introduce more interference since all of them work on same frequency band. This limits the capacity of femto cell users. Femto cells may also introduce interference to macro cell users, this again reduces the capacity of Macro cell users. The(More)
In 4G and beyond 4G cellular communication systems, multi-hop relay network (MHR) plays a vital role. Improper deployment of relay station (RS) in MHR network creates some severe issues. The conventional studies on RS deployment have not considered the practical issue of link overloading. In this paper, a two-phase, fuzzy based selection and deployment(More)
Disaster Management System (DMS) is a key solution for humanitarian relief from natural disasters and manmade disasters. This paper discusses the use of Orthogonal Frequency Division Multiplexing (OFDM) in DMS. OFDM is a multicarrier modulation (MCM) in which single data stream is transmitted over a number of lower rate sub carriers. The main reason to use(More)
Desquamative gingivitis (DG) is a clinical condition in which the gingiva appears reddish, glazed, and friable with loss of superficial epithelium. DG is considered a clinical manifestation of many gingival diseases and hence not identified as a diagnosis itself. Mucous membrane pemphigoid (MMP) is an autoimmune vesiculobullous disorder of mucous membrane(More)
