In mobile ad-hoc radio networks, terminals are mobile and
heterogeneous, the architecture of the network is continuously
changing, communication links are packet oriented and radio
resources are scarce. Therefore, mechanisms on how to access
the radio channel are extremely important in order to improve
network efficiency and, when needed, to guarantee QoS.
However, due to these network harsh conditions, decentralized
Medium Access Control (MAC) protocols designed
specifically for ad hoc networks are scarce. In this paper we
present a novel decentralized multiaccess MAC protocol for
Ad Hoc networks. This MAC protocol is an hybrid CDMATDMA
in which a cross layer approach has been followed in
order to maximize network throughput. A theoretical analysis
of the system is presented ending up with closed expressions
for the throughput and delay of the network and some
simulations are presented to evaluate the performance of the
system. |
