Today, the \"prime mover\" of the world is information, particularly, secret information. It is also a commodity whose value perishes with time. This dual-quality of power and perish-ability makes information to be the wealth, most difficult to protect on the earth. Nevertheless, in order to protect the secret information, technology has given us methods which provide security, though not a fool-proof one. Steganography is one such method which incorporates security by hiding the very existence of the secret by camouflaging it inside an image. In addition to the enormous security provided by the steganographic algorithms, if we implement some security in the very methodology of transmission and reception of an image, it would prove to be an useful venture. Such an useful venture is proposed in this paper, where four different users can transmit secret messages through a single stego image by taking advantage of the OFDM-QPSK(Orthogonal Frequency Division Multiplexing-Quadrature Phase Shift Keying) duo, thereby imparting multiple-access and improving security in an otherwise normal stego image. Comparison of BER in AWGN and Random Noise channel has also been done in order to quantify the effectiveness of the proposed technique.","PeriodicalId":68078,"journal":{"name":"无线互联科技","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82808789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The straightforwardness with which HAPS gets along with a telephone network service provider or the Internet, has made it to a unique feature of future wireless networks. Most HAPS' criteria have been well circumscribed by the International Telecommunication Union (ITU) or subscribed to in World Radiocommunication Conferences (WRCs). This procedure will prolong to function the various frequency ranges in future, most notably in WRC-12. To curb and clarify assessment probe, it should be explicated that FSS links are sited in C-Band frequency range to condense overwhelming conceivable propagation attenuation attributable to disproportionate rain amount in tropical and subtropical regions. Consequently, FSS uplink is ranged between 5925 and 6725 MHz. Where as, HAPS gateway links' frequency range is delineated between 5850 and 7075 MHz. Hence, FSS uplink intervenes with HAPS frequency range partially. Accordingly, HAPS spectrum sharing with FSS uplink in the Frequency range 5850–7075 MHz is appraised at this juncture. HAPS spectrum implementing in alluded frequency range instigates interference renowned as Co-Channel Interference (CCI). CCI reckoning is based upon Spectrum Emission Masks (SEM), Antennas' Radiation Pattern and Clutter Loss. The co-channel frequency deployment prospects are delved at this article.","PeriodicalId":68078,"journal":{"name":"无线互联科技","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78675787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover in real time application domains delay even by fraction of a second may deceive the purpose of the application. Therefore, designing an attack-defending scheme for WSN without involving any additional delay in data-forwarding is an important challenge in this domain. The present work proposes a data-forwarding scheme having no additional delay to defend jamming attack in WSN. The scheme considers a multilayer architecture where the layers are made up of hexagonal cells each containing sensor nodes in the form of clusters. The nodes are randomly deployed throughout the network and clusters are formed so that every cell hosts two sets of clusters operating in two different predefined frequencies. We have provided design guideline to determine cell size in terms of network parameters. This guideline ensures that for a cluster head there is at least another cluster head at one-hop distance towards the sink and thereby ensures data-forwarding in shortest path. During data-forwarding, if a frequency is jammed, the cluster operating in that frequency becomes inoperative and the other cluster acts as back-up. We claim that the scheme defends jamming attack without incurring any additional delay and the claim is substantiated through simulation.","PeriodicalId":68078,"journal":{"name":"无线互联科技","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84672537","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
