Mobile Ad-Hoc Network Security: An Overview

In the golden era of modern science, the explosive expansion of mobile computing devices, which principally take into account laptops, personnel digital assistants (PDAs) , handheld digital devices and etc., has incited a revolutionary amendment to the computing world. Thus the ubiquitous computing environment has been formed, which is wireless Mobile Ad Hoc Network and attracted most concentrations from many proficient researchers. But Mobile Ad Hoc Networks have far more vulnerabilities because of security threat, which is very much hard to maintained comparing to wired networks. Endeavour of so many researchers is yet to be finished for the innovation of a secured framework for Mobile Ad Hoc Network (MANET). In this paper, different security aspects of wireless networks are addressed and diversified methodologies of various researchers are discussed from the very beginning of this research to this modern age. The effort has been given here to observe the trends of numerous security standards. Also some promising approaches are indicated and particular concentration is devoted for the scrutinizing a range of procedure from raw level to high professional, so that in future one can get precious guideline for further betterment. Furthermore, the related work on this arena will give a paradigm of challenges and explore the scopes for research work in de pth of wireless security.
