A mobile ad hoc network (MANET) is a collection of wireless mobile nodes communicating with each other using multi-hop wireless networks. One of the main challenges of MANET is the design of robust routing algorithms that adapt to the frequent and randomly changing network topology. This feature leads to frequent path failures and route reconstructions, which causes an increase in the routing control overhead. A variety of routing protocols have been proposed and several of them have been extensively simulated or implemented as well. Existing distance based routing protocols like Ad-hoc On-demand Multipath Distance Vector (AOMDV) routing protocol, which is a multipath routing protocol, Destination sequence distance vector (DSDV) routing protocol, Distance Routing Effect Algorithm For Mobility (DREAM), Secure Efficient Distance Vector Routing For Mobile Wireless Ad Hoc Networks (SEAD), and Polarized Gossip Protocol (PGP) are analyzed and concluded that PGP performs well compared to other protocol mentioned above. In proposed work the position-based routing features combined into on-demand routing protocols and proposes a distance based routing protocol (EDRP) in the absence of positioning service to improve the route discovery.Keywords

Image spam is a type of e-mail spam that embeds spam text content into graphical images to bypass traditional text based e-mail spam filters. To effectively detect image spam, it is desirable to leverage image content analysis technologies. A solution to determine spam images is to embed both server-side filtering and client-side detection. On the server-side, spectral clustering algorithm is used and in the client-side detection, active learning principle is used. By using spectral clustering algorithm on the server side, it will cluster the spam images and filter the attack activities of spammers and fast trace back the spam source. By using active learning on client-side filtering, the learner guides the users to label as few images as possible while maximizing the classification accuracy. The server-side filtering identifies large image clusters as suspicious spam sources and filtering method is performed to identify the real sources and block them from beginning.Keywords

Background: Honey, a multifaceted mixture of enzymes, peptides and amines, has domestic as well as medicinal utility. Recent studies that analyzed its effects in different strains of rat and mouse have pronounced honey as antimetastatic with moderate antitumor effects. In the present study we have tested the cytotoxic activity of diluted unfractionated bee honey against Saos-2 (Sarcoma osteogenic) cell line, a primary osteosarcoma in vitro, to demonstrate that honey can induce apoptosis in primary osteosarcoma cells. Methods: The cytotoxicity effect of honey was evaluated on SAO’S cells and cell cycle analysis was performed using propidium iodide. To look for DNA breaks in cells, DNA of the sample was run through electrophoresis in standard TE buffer to visualize DNA separation pattern on a UV Transilluminator. Results: Cell viability was steadily lost with increasing concentrations of honey and IC50 value for honey was found to be lower than methotrexate drug. Phase contrast microscopy showed that cell appearance was indicative of apoptosis. Results showed that Honey showed an arrest at G0/G1 phase. DNA fragmentation exhibited DNA fragmentation. Methotrexate in combination with honey resulted in the formation of a set of defined wreckage as characteristic of apoptosis. Discussion: The study indicates that honey can be considerably effective against cancer cell lines in vitro. Further in depth study would help to explain the exact mechanism of action of honey against cancer cells and other malignancies.Keywords
