Security & cooperation mechanisms over mobile ad hoc networks: A survey and challenges

In our everyday life, we are very interested in wireless connection technologies. In addition, the use of mobile devices and applications which are based on wireless networking is continuously increasing day after day. As the future Internet architecture, security concept can offer superior architectural support for Mobile Ad Hoc Networks (MANETs). Therefore, this concept, which is an important cross-cutting research field, is gradually forming. The key novelty of this paper, is to provide the references and guidelines to well guide the readers approaching studies on the new research fields about this concept. First of all, we introduce the background of MANETs and analyze its development trends, and then interpret security requirements and sketch an overview about challenges and attacks in such networks. Subsequently, we define, for the first time a new research field entitled Cooperative Internet of MANETs (CIMANET) which will be introduced as the new cross-cutting area. In addition, we provide a description of many existing security algorithms with a comparative analysis of these various mechanisms.
