Detecting node failures in Wireless Sensor Networks is very challenging because the network topology can be highly dynamic, the network may not always connected and the resources are limited . It becomes trend to deploy the large number of portable wireless sensors in Wireless Sensor Networks, in order to increase the Quality of Service (QoS). The QoS is mainly affected by the failure of sensor node .The sensor node failure increases with the increase in number of sensors in Wireless Sensor Networks. In order to maintain better QoS in such failure condition, Identifying and Detaching such faults are essential. In the proposed method the faulty sensor node is detected by measuring the Round Trip Delay (RTD) time of Discrete Round Trip paths and comparing them with threshold value. In proposed method, Scalability is verified by simulating the WSNs with large numbers of sensor nodes in NS2. The RTD time results derived in hardware and software implementation are almost equal, justifying the real time applicability of the investigated method.","PeriodicalId":415674,"journal":{"name":"International Journal of communication and computer Technologies","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123413274","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}

{"title":"An improved RSA image encryption algorithm using 1-D logistic map","authors":"H. J. Yakubu, T. Aboiyar, P. B. Zirra","doi":"10.31838/ijccts/04.01.01","DOIUrl":"https://doi.org/10.31838/ijccts/04.01.01","url":null,"abstract":"The need to have a more secured ways of protecting sensitive images in this modern age of technology has become necessary \u0000for ensuring that such images sent via the insecure public network called the Internet are protected from attacks. To this end, various \u0000image encryption algorithms have been proposed by many researchers and RSA image encryption algorithm is one of them. Studies on \u0000RSA image encryption algorithm reveal that some images when encrypted using the algorithm, gives encrypted images that do expose \u0000some features of the plain images on visual inspection no matter the size of primes used. This is due to the fact that digital images have \u0000high redundancy and high correlation of image data that make RSA algorithm image dependent. Cryptanalysis has been a major source \u0000of concern (in particular the brute-force attack) when designing a cryptosystem since it is assumed that the cryptanalyst knows exactly \u0000the design and working of the cryptosystem under study except the secret key. Thus, making the secret key access much more difficult to \u0000the cryptanalyst makes the encryption algorithm a more reliable one. In view of these, an improved RSA image encryption algorithm \u0000using 1-D logistic map was proposed. The proposed scheme has two stages. In the first stage, the plain-image is shuffled using the chaotic \u0000properties of the map and in the second stage; the shuffled image is encryption using the RSA algorithm. The proposed algorithm and \u0000the RSA algorithm were tested on two standard test gray scale images: cameraman.tif and clock.tif using four different set of keys. Security \u0000analysis such as histogram analysis and correlation coefficient analysis were also carried out on the results obtained from the two \u0000methods. The results of the analysis show that the proposed scheme is more secured and stronger against the brute-force attack ( encrypted \u0000image which does not reveals any hint about the plain image to the attacker and also its key space has double: the two primes, \u0000initial condition and control parameter) than the RSA image encryption scheme.","PeriodicalId":415674,"journal":{"name":"International Journal of communication and computer Technologies","volume":"26 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123657622","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}

In this mesh network, load balancing can be used to extend the lifetime of a mesh network and thus reducing the traffic congestion and improves the network performance. The clustering techniques are used to solve routing and congestion control problems, because it offers scalability and enhance the availability of network and reduce overhead. Here a Weighted Clustering Algorithm (WCA) method is selected to divide the network into k –cluster to manage the load in small scale and hence to reduce the overhead. The node with maximum weight is more desirable to select as Cluster Head (CH).By using the AODV protocol a node in the cluster sends many small packets compared to other reactive protocols to increase the speed of the transmission packet. When the network size increases, the degree of node also increases causing network congestion. The use of this WCA reduces this overhead by allowing route discovery and maintenance.","PeriodicalId":415674,"journal":{"name":"International Journal of communication and computer Technologies","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122824831","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}
