Wireless ad hoc networks are one of recent most interesting rising technologies. An ad hoc network consists of nodes that must communicate with each other without relying on any infrastructure or pre-defined hierarchy. Medium Access Control (MAC) protocols provide a means to nodes to access the wireless medium efficiently and collision free to the best of their ability. MAC layer protocols allow a group of users to share a communication medium in a fair, stable and efficient way. Ad hoc wireless networks present even greater challenges than infrastructure wireless networks at the MAC layer.
