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). The union of nodes forms an arbitrary topology. This flexibility makes them attractive for many applications such as military applications, where the network topology may change rapidly to reflect a force’s operational movements, and disaster recovery operations, where the existing/fixed infrastructure may be nonoperational. The ad hoc self-organization also makes them suitable for virtual conferences, where setting up a traditional network infrastructure is a time-consuming high-cost task.
