Wireless networks are built upon a shared medium which makes it easy for an adversary to launch a Denial of Service (DoS) attack. Jamming, as a part of DoS attacks at physical layer, is one of the main security considerations within the wireless networks. It holds the potential to totally cripple the network and cause a loss of service and revenue. Jamming attacks can severely interfere with the normal operation of wireless networks and, consequently, mechanisms are needed that can cope with jamming attacks. Jamming techniques vary from simple ones based on the continual transmission of interference signals, to more sophisticated attacks that aim at exploiting vulnerabilities of the particular used protocol. Considering the fact that the jamming is one of most common attacks against military communications, this paper is examining the wireless military network behavior in the presence of such attacks. For this purpose we simulate the effects of the various jamming attacks using OPNET Modeler. Several effective counter-measures against low power jamming are proposed. These measures are based on both transmit power and packet reception power threshold optimization, supported by spread spectrum techniques. The results are considerably improved when all of these mechanisms are combined. © 2014 IEEE.

The “resurrection plant” Ramonda serbica is included in the Albanian and Bulgarian list of endangered plants as a rare, Balkanic-endemic species and tertiary relic species, while R. nathaliae is characteristic in the FYROM area. Our research groups have established national in vitro collections of R. serbica in Albania and Bulgaria and R. nathaliae in Macedonia. The aim of this joint study is (1) the choice of successful micropropagation methods as the basis for the in vitro collections and (2) the evaluation of polymorphism of some natural populations. In both collections, seeds were used as a convenient starting point for micropropagation in the nutrient medium JG-B. In the Bulgarian in vitro collection, a dry sterilization of seeds was applied for a first time for Gesneriaceae family. The micropropagation and conservation of Ramonda seeds and plantlets were similar in Albanian and Bulgarian collections. The plantlets in vitro as an explant material were developed in JG-B medium with different phytohormones. The direct organogenesis of two Ramonda species is very similar models. The method of conservation in vitro with minimal growth method (modification of nutrient medium) was used. Meiosis and mitosis examinations of the natural populations and plantlets cultivated in vitro were carried out by standard Squash method. Cytogenetical study of natural populations showed polyploid forms as a mixture (2n=72) and (2n=96). Mitosis preparations in plantlets in vitro showed a predominance of the most frequent form (2n=96). The biodiversity in interspecific level of the natural populations of Ramonda serbica of Central Albania, R. nathaliae from Macedonia and cultivated plantlets in vitro from Albania and Bulgaria was evaluated via molecular markers (RAPDs). The micropropagation method is a convenient way for the international exchange of germplasm of rare and endemic plants. From the data obtained in this study it can be concluded that RAPD markers provided a useful technique to study genetic diversity in Ramonda serbica and R. nathaliae populations. This technology allows the identification of different populations as well as the assessment of the genetic similarity among different populations. © 2012 Taylor and Francis Group, LLC.

The desiccation-tolerant plants of the R. serbica and R. nathaliae are resurrection plants which are able to fully recover their physiological function after anabiosis. A comparison of chlorophyll fluorescence imaging and photosynthetic pigment contents responses of R. serbica and, for the first time, R. nathaliae to dehydration and rehydration were investigated. For this purpose, plants after collection from their natural habitats were kept fully watered for 14 days at natural condition. The experiment was conducted with mature leaves of both species. R. serbica and R. nathaliae plants were dehydrated to 5.88 % and 7.87 % relative water content (RWC) by withholding water for 15 days, afterwards the plants were rehydrated for 72 hours to 94.67 % and 97.02 % RWC. During desiccation, R. serbica plants preserved the chlorophyll content about 84 %, while R. nathaliae about 90 %. During dehydration when RWC were more than 40 %, photochemical efficiency of PSII for photochemistry, the Fv/Fm ratio, decreased about 40 % in R. nathaliae plants, but a strong reduction with 60 % was recorded for R. serbica. Following rehydration, the Fv/Fm ratio recovered more rapidly in R. nathaliae. The higher photosynthetic rates could also be detected via imaging the chlorophyll fluorescence decrease ratio Rfd, which possessed higher values after rehydration leaves of R. nathaliae as compared to R. serbica. The results showed that the photosynthetic activity and chlorophyll contents after rehydration are recovered more rapidly in R. nathaliae in comparison to R. serbica. © 2013 Prof. H.S.

Ramonda serbica and Ramonda nathaliae are rare and endemo relict plant species from Balkan Peninsula. An efficient micro propagation and in vitro conservation method via direct and indirect organogenesis from seed and leaf explants, respectively, was established in this study. The seed of both Ramonda species were collected from different populations in Kosovo, and were germinated in nutrient media JG-B without any phytohormone. The highest number of shoots and multiplication rate was observed on JG-B medium supplemented with BAP and IAA (0.5 mg l−1 each), whereas the highest number of leaves per plantlets was found on WPM and RA medium supplemented with BAP and IAA (0.1 mg l−1 each). During this stage of micro propagation some significant differences were observed in plantlets from different populations. The indirect organogenesis from parts of leaves of natural plants was not successful due to unavailability of established protocol for disinfections of the plant material. On other hand, parts of leaves from micro propagated plantlets, cultured on MS medium supplemented with different ratio of BAP and NAA, resulted in the highest efficiency for shoot regeneration. In vitro conservation of micro propagated plants at the lower temperature (4 °C) had a significantly positive effect for storage of more than 12 months. © 2014, Prof. H.S.
