ASSESSMENT OF SECURITY IN MOBILE AD-HOC NETWORKS (MANET)

[摘要] With the proliferation of cheaper, smaller, and more powerful mobile devices, mobile ad hoc networks (MANETs) have become one of the fastest growing areas of research. This new type of self-organizing network combines wireless communication with a high degree node mobility. Unlike conventional wired networks they have no fixed infrastructure (base stations, centralized management points and the like). Mobile ad hoc networks (MANETs) are one of the fastest growing areas of research. Conventional networks use dedicated nodes to carry out basic functions like packet forwarding, routing, and network management. In ad hoc networks these are carried out collaboratively by all available nodes. In this paper, we’ll discuss about the MANET specific attacks, security challenges, goals and protocols alongwith the techniques used to secure MANETs.
