A simulation design for link connection-oriented wireless mesh networks

Medium access control (MAC) is an intermediate layer to manage the policy of link transmissions so that nodes in the same network segment can send packets without constant interference from other nodes. It should give each node the opportunity to transmit packets successfully. Most existing wireless LAN techniques use contention-enable MACs, which are statistical multiplexing algorithms to control multiaccess. Compared to them, regular division-based MACs, such as time division multiplexing (TDM) or frequency division multiplexing (FDM), are seldom used in wireless LANs due to the inefficiency that is shown by the inflexible dynamic bandwidth allocation to nodes. Quality of service (QoS) takes into account this inflexibility in resource reservation in order to grant enough resource to services, even when they are idle. As a result, link connection-oriented networks with mesh topology are considered a good research topic. The corresponding simulation model is required where most current simulation tools do not provide one directly. We present a simple link connection-oriented network simulation design in C without using any existing simulation packages. It can help researchers to design the overall simulation in other related areas, and later it could be extended to a complete simulation tool.
