Abstract

Recently, ad-hoc networks have obtained a growing interest due to 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. Moreover the growth of several applications with different requirements in terms of QoS has raised the problem to manage their priority also at the MAC layer. This paper deals with a traffic priority management technique at the MAC layer based on the code division multiple access (CDMA) scheme, where an adaptation of the used spreading factor to the network congestion is foreseen in order to minimize the energy consumption and maximize the network throughput
