Fuzzy Trust Protocol for Malicious Node Detection in Wireless Sensor Networks

Abstract: Wireless sensor networks (WSNs) are used in many applications nowadays, because of its extensive usage. Due to the distinct characteristics, they are vulnerable to many attacks. To secure WSN, trust management plays a pertinent role. In trust based security model, decision is taken based on some specific behavior, and so it has uncertainty. Fuzzy logic deals with uncertainty and has tolerance of imprecise data with high power of precision. In this study, fuzzy logic based multi-attribute trust model is suggested. The proposed trust model has message success rate, elapsed time at node, correctness and fairness as trust metrics. Once the four trust values are calculated, fuzzy computational theory is applied to compute the final trust value of every node that can be anyone of low (l), medium (m) and high (h). Simulation results show that the fuzzy based multi-attribute trust evaluation outperforms weighted summation based multi-attribute trust evaluation.

Exponentially localized solutions of Mel'nikov equation

Abstract: The Mel'nikov equation is a (2+1) dimensional nonlinear evolution equation admitting boomeron type solutions. In this paper, after showing that it satisfies the Painleve property, we obtain exponentially localized dromion type solutions from the bilinearized version which have not been reported so far. We also obtain more general dromion type solutions with spatially varying amplitude as well as induced multi-dromion solutions.

Recent advances in the study of toxicity of polymer-based nanomaterials

Abstract: Polymeric nanoparticles (NPs) are colloidal particles with size ranging from 1 to 1000 nm. They are comprised of active pharmaceutical ingredients that are within/adsorbed macromolecular substances (polymer). Due to quantum size effects, polymeric NPs affect their toxicity which are attributed to oxidative stress, cytotoxicity, and genotoxicity. Nanodiamonds have become a subject of lively research due to their attractive properties. Polymeric NPs have been used to remove toxic heavy metals. Multilayered NPs, functionalized inorganic or organic polymeric materials, coatings and hydrogels have revealed their potential for environmental and communal health applications. Polymer-NP composite materials have exclusive characteristics, such as high mechanical strength, good electrical conductivity, optical and thermal properties. New fluorescent nanomaterials, inspired from the fields of polymeric drug delivery vehicles and advanced fluorophores, can combine superior brightness with biodegradability and low toxicity.
