Ayurveda Perspectives on Visha & Upavisha Dravyas as Rasaushadhi: A Review

Ayurveda is science of long and healthy live which focuses on treatment of diseases. Ayurveda works around management of physical and mental health using various medicines involving herbs, metals and minerals. Ayurveda encompasses different stream including Rasashastra which utilizes Rasa drugs for therapeutic purposes. Many mineral, metal and plant based compounds involved in the preparation of formulations belong from Rasa category. These compounds may possess some toxic effects and utilizes only after proper purification process. Therefore it can be stated that Upavisha Dravyas can be used for health benefits after purification measure. Rasa-shastra involves utilization of many poisonous herbs, metals and minerals. Considering the therapeutic significance of such compounds this article exploring critical aspects of Upavisha Dravyas in Rasa-shastra

Performance Evaluation of Different Routing Protocols in IPv4 and IPv6 Networks on the Basis of Packet Sizes

AbstractIPv6 is the next generation internet protocol which will eventually replace IPv4, but till then both the protocols need to coexist for a long time. The main issue is of compatibility; both the protocols are not compatible with each other. A different set of routing protocols is required for IPv4 and IPv6. These protocols have different performances for different scenarios. Routing is a very challenging task especially in case of wireless networks. In this paper the performance is evaluated for different routing protocols like RIP, RIPng, OSPFv2 and OSPFv3 for IPv4 and IPv6 networks over Mobile Adhoc Networks. Simulations are carried out on Exata Cyber 1.1 Simulator. The performance of networks is measured on the basis of following parameters: throughput, end-to-end delay, jitter and packet delivery ratio with varying packet sizes of 256, 512, 1024 and 2058 bytes

Analysing Mobile Random Early Detection for Congestion Control in Mobile Ad-hoc Network

This research paper suggests and analyse a technique for congestion control in mobile ad hoc networks. The technique is based on a new hybrid approach that uses clustering and queuing techniques. In clustering, in general cluster head transfers the data, following a queuing method based on a RED (Random Early Detection), the mobile environment makes it Mobile RED (or MRED), It majorly depends upon mobility of nodes and mobile environments leads to unpredictable queue size. To simulate this technique, the Network Simulator 2 (or NS2) is used for various scenarios. The simulated results are compared with NRED (Neighbourhood Random Early Detection) queuing technique of congestion control. It has been observed that the results are improved using MRED comparatively
