Medium access control protocol for CDMA ad hoc networks

Recently, ad hoc networks have obtained a growing interest because of their advantages in many practical applications. One of the most critical points is the definition of an efficient medium access control (MAC) protocol that allows the transmission of packets generated by a node and routing of packets arriving from other nodes. A MAC technique is presented based on the code division multiple access (CDMA) scheme that adapts the used spreading factor to the network congestion in order to minimise the energy consumption and maximise the network throughput.
