Simulation and analysis of authentication protocols for mobile Internet of Things (MIoT)

Abstract: Things are integrated for increasing the availability of information. MIoT is the connectivity of mobile devices to extend the information. Connectivity of mobile devices helps in managing the various social activities. Security is a major concern while integrating the heterogeneous devices in these social networks. Things embedded with radio frequency based identifications are having scarcity of resources thus require lightweight cryptography aspects. This work proposes a single bar circular topology based authentication protocol for MIoT. This protocol helps in authenticating the mobile devices for constructing secure network. The proposed protocol is modeled using Alloy model. Delay analysis shows that construction of secure network is possible with maximum delay of 0.91 msec. Node can enter or leave the network with minimum of 0.13 and maximum of 0.20 msec. Further, Zone Routing Protocol (ZRP) is considered to be the best protocol for constructing a secure network.

Natural Selection Mediated Association of the Duffy (FY) Gene Polymorphisms with Plasmodium vivax Malaria in India

Abstract: The Duffy (Fy) antigens act as receptors for chemokines as well as for Plasmodium vivax to invade human RBCs. A recent study has correlated the occurrence of the FY*A allele of Duffy gene with decreased susceptibility to vivax malaria, but no epidemiological correlation between the distribution of FY*A allele and incidences of vivax malaria has been established so far. Furthermore, if such correlations exist, whether natural selection has mediated the association, is an important question. Since India is highly endemic to P. vivax malaria with variable eco-climatic and varying vivax malaria epidemiology across different regions, such a question could well be answered in Indians. For this, we have genotyped the FY gene at the −33rd and the 125th nucleotide positions in 250 Indians sampled from six different zonal plus one tribal population covering the whole of India and studied possible correlations with eco-climatic and vivax malaria incidences. No FY*O allele was found, however, both the FY*A and FY*B alleles forming FY*A/FY*A, FY*A/FY*B and FY*B/FY*B genotypes were widely distributed among Indians. Five out of seven population samples significantly deviated from the Hardy-Weinberg equilibrium expectation, and two alleles (FY*A and FY*B) and the homozygote genotype, FY*B/FY*B were clinally distributed over the population coordinates. Furthermore, vivax malaria incidences over the past five years were significantly negatively and positively associated with the frequencies of the FY*A and FY*B alleles, respectively. The Northern Indians were highly differentiated from the other zonal population samples at the FY gene, as evidenced from the reconstructed Neighbor-Joining phylogenetic tree. The results specify the role of natural selection in the distribution of FY gene polymorphism in India. Furthermore, the hypotheses on the part of the FY*A allele in conferring protection to vivax malaria could be validated following population genetic studies in a vivax malaria epidemiological setting, such as India.
