Herbal plants are integral parts of the traditional medicine worldwide and most of the rural and urban population uses these plants in many of their regular needs even today. The current researchers are more focused on natural chemicals than the synthetic chemicals due to their environmental, economical and health benefits. Plants produce many chemical compounds for its biological activities including defence mechanism against microbes, insects and herbivorous animals and these chemicals are called as phyto chemicals. Herbal plants are a natural source of many important phyto chemicals and widely used in Pharmaceutical, food and cosmetic industries. A wide variety of herbal plants are available in the Indian subcontinent and they are the backbone of Indian traditional medicines Ayurveda and Siddha. Leucas aspera Linn., commonly known as Thumbai or Dronpushpi is a small, erect, branched annual aromatic herb, distributed throughout India from the Himalayas down to Ceylon. Though it grows as a weed throughout the country, it has a number of medicinal values and it is used in traditional medicine to treat many diseases. The study of various biological properties of this plant will be useful for its potential use in respective industries. Medicinally, it has been proven to possess various pharmacological values like antifungal, antipyretic, antioxidant, antimicrobial, antinociceptive, analgesic, antidiarrheal, insecticidal, antiinflammatory and cytotoxic activity in a number of studies by different researchers in the past several years. The available reports on antimicrobial activity, antioxidant activity and pharmacological value of L. aspera are discussed in this review.

The main goal of this paper is to improve security level of packet scheduling by considering service dependencies of packets at each node. Service dependencies of packets are collected by using monitoring agents and the central authority is employed to integrate all the collected data in monitoring agents.. Packet service dependency can be concerned with both intra service dependencies and inter service dependencies. Intra service dependent security aware packet scheduling algorithm (ISDSPS) is proposed for maximizes the performance of packet scheduling. ISDSPS clusters the packets according to their client service request. Packets related to client service are grouped in intra service dependency cluster and packets that are not related to client service are grouped under inter service dependency cluster. Sometimes there may a chance of misclassification of packets. For effective clustering and scheduling, Intra and inter service dependent security aware packet scheduling (IISDSPS) is proposed for considering intra service dependency packets in inter service dependency clusters during packet scheduling process.

INTRODUCTION In mobile ad-hoc networks (MANET), the most significant issue is anonymous communication. The anonymous communication is mostly utilized for protecting the source and destination of the communication link and the other intermediate nodes involved in communication connection which is difficult to find by the impostors. Different techniques are provided for improving the anonymous communication in MANET. However, MANET is vulnerable under particular circumstances such as passive attacks and traffic analysis attacks. In addition, the security-aware packet scheduling algorithm has less effectiveness since the attacker may easily identifies the source-destination links. II. INTRA-INTER AND MULTIPLE LAYER SERVICE DEPENDENT SECURITY-AWARE PACKET SCHEDULING (IIMLSDSPS)The correlation of the dependencies between multiple layers such as service layers and network layers are considered with ISAPS algorithm. In the proposed method, the monitoring agents are used for collecting the dependency data from service layers and network layers. The collected data are correlated and utilized in the construction of the service layer dependence graph (SLDG). The directed acyclic graph is utilized as the local dependency graph while SLDG is utilized as global dependency graph. In addition, this approach is used for resolving the constraints by building the hypothesis list and rating the constraints for reducing the performance degradation. The policies which are employed across the networks are considered as constraints as they preclude the particular services from running on specific nodes or preclude two services from interacting. Therefore, the correlated dependencies across multiple layers are considered for enhancing the packet level security. III. ANONYMITY-BASED INTRA-INTER AND MULTIPLE LAYER SERVICE DEPENDEN...
