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":"23 1","pages":"1-5"},"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":"16 1","pages":"1-6"},"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}

Because WSNs in general and in nature are unattended and physically reachable from the outside world, they could be vulnerable to physical attacks in the form of node capture or node destruction. These forms of attacks are hard to protect against and require intelligent prevention methods. It is necessary for WSNs to have security measures in place as to prevent an intruder from inserting compromised nodes in order to decimate or disturb the network performance. In this paper we present an intrusion detection algorithm for wireless sensor networks which does not require prior knowledge of network behavior or a learning period in order to establish this knowledge. We have taken a more practical approach and constructed this algorithm with small to middle-size networks in mind, like home or office networks. The proposed algorithm is also dynamic in nature as to cope with new and unknown attack types. This algorithm is intended to protect the network and ensure reliable and accurate aggregated sensor readings. Theoretical simulation results indicate that compromised nodes can be detected with high accuracy and low false alarm probability.","PeriodicalId":68078,"journal":{"name":"无线互联科技","volume":"10 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2011-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72951574","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}
