Objectives: To develop a new multipath load sharing algorithm using channels sensing, node energy level analysis and malicious node detection. It aims at finding an efficient load sharing technique that gives better throughput delivery, less delay and security for data transformation. Methods/Analysis: A channel sensing between the nodes is performed to measure the signal to noise ratio and reject the path if the noise strength is greater than the signal strength. Prior energy level analysis is done for consistent data transmission over a period of time without any interrupt. A watchdog timer method is adopted for malicious node identification and removal. Findings: The quality of service in MANETs has been improved such as throughput has been increased 15% and packet delivery ratio has been increased 20% and the overall delay has been minimized 27%. Conclusion/Application: We proposed an efficient best path selection load sharing algorithm, which involves channel sensing, node energy level analysis and malicious node removal for security concern.Keywords

All the three plant species selected for the study are short lived medicinal herbs. Eclipta alba is mostly found in marshy areas while Emilia sonchifolia and Vernonia cinerea are mostly seen along road sides and in waste lands. IVI shows that all the three species are not dominant in the habitat.Full Text

The tribal and generic-level phylogeny of Scarabaeinae (Coleoptera: Scarabaeidae) dung beetles have been often debated globally. However, fauna from India have not been a part of these analyses due to lack of data. We used partial sequences of 16S mtDNA gene of dung beetles collected from different parts of the Western Ghats, India, to examine (i) the tribal positions of Onthophagini, Onitini and Oniticellini, and (ii) the phylogenetic position of different genera of Onthophagini. We found that Oniticellini nested within Onthophagini, suggesting the invalid position of Oniticellini. The non-Onthophagus genera of Onthophagini – Caccobius, Cleptocaccobius, Milichus – nested within Onthophagus, suggesting that these three genera might be invalid and could be subgenera of Onthophagus. Onitini formed a separate clade in the phylogenetic tree. The results suggest for tribal-level reclassification of dung beetles, as noted in previous studies. The present study may enrich the molecular data of the Indian dung beetles, which are currently lacking.Keywords
