Routing protocols in mobile Ad-hoc networks

The routing protocols will be a fundamental piece in the operation of ad-hoc networks. This protocols must fulfill the main objective of using valid routes among the different nodes that form the net in a correct and efficient way keeping in mind the possibility that malicious nodes may exist in the net, and protecting the communication of non-allowed accesses. Moreover, it will be convenient that the messages should be delivered by following a protocol that bears the lowest consumption of both bandwidth and energy. In this article an analysis of the routing protocols proposed in the bibliography for ad-hoc networks is presented. Always looking for a balance between good operation and security in the routing and a low level of net saturation which could lead into an undesirable overload in the nodes.
