ABSTRACT
An ad hoc network is a wireless network that is established without the aid of infrastructure or centralized administration. It is formed by a group of wireless terminals such that a communication between any two terminals is carried out by means of a store-and-relay mechanism. The design of routing algorithms in ad hoc networks is a challenging task. Algorithms must provide for a high degree of sophistication and intelligence so that the limited resources inherent to the wireless systems can be dealt with efficiently. Medium access control for wireless ad hoc networks is currently a very active research topic. The characteristics of the network, the diverse physical-layer technologies available, and the range of services envisioned render a difficult task the design of an algorithm to discipline the access to the shared medium that results efficient, fair, power consumption sensitive, and delay bound.
