A Mobile Ad-hoc Network (MANET) is a self configuring network composed of mobile nodes without any fixed infrastructure. A very important and necessary issue for mobile ad-hoc networks is to find the route between source and destination that is a major technical challenge due to the dynamic topology of the network. Routing protocols for MANETs could be differing depending on the application and network architecture. There are various routing protocols that have been proposed for MANETs, it is quiet difficult to cover all of the protocols. In this survey paper, we present typical routing protocols based on unicast, multicast and geocast, which reflects the state of-the-art of research work on mobile ad-hoc network routing. Another criteria for classifying the routing protocols for Mobile Ad-hoc Networks, i.e. proactive, reactive and hybrid approaches have been later used in every of the unicast routing protocol and multicast routing protocol classification. This paper also provides an overview of the routing protocols by presenting their characteristics, functionality, benefits and limitations.Keywords

In this work, the oxidation of methanol was carried out using Ni and Ni-Co alloy electrodeposited on stainless steel mesh substrate with a view to replace expensive and sensitive platinum and platinum alloy catalysts. The performance of electrode was assessed through cyclic voltammetry in alkaline media. The operating conditions of the electrode were optimized.

The Schiff bases namely 5-Me SALAAP, 3-OMe SALAAP, 3-Br, 5-Cl SALAAP have been prepared by reacting 4- amino antipyrine with 5-methyl salicylaldehyde/3-methoxy salicylaldeyde /3-Br, 5-Cl salicylaldehyde. The Cu(II) complexes have been prepared by reacting copper(II) chloride with those of Schiff bases in alcoholic medium .The complexes are non electrolytes in DMSO. These have been characterized by using elemental analysis, IR, UV-VIs, 1H, 13C NMR, Mass spectra, ESR spectra, Magnetic susceptibility, conductance measurements and thermal (TGA and DTA) anaylsis. The complexes were found to have composition ML2.On basis of elemental and spectral studies, six coordinated geometry is assigned for these complexes. The Schiff bases act as tridentate and coordinate through the azomethine nitrogen, carbonyl oxygen and phenolic oxygen respectively. Binding of synthesized complexes with calf thymus DNA (CT DNA) was studied by spectroscopic methods. The synthesized ligands and their metal complexes were screened against bacteria. (E.coli and Staphylococcus aureus). The activity data show that the metal complexes are more potent than Schiff bases.
