Abstract:
Ad hoc wireless networks are a very potential field offering lot of scope for research. In these networks, the Medium Access Control (MAC) protocols are responsible for coordinating the access from active nodes. These protocols assume greater significance since the wireless communication channel is inherently prone to such problems as hidden terminal, exposed terminal and fading effects .The scheme proposed here is used to perform priority scheduling in nodes resolving any contention scenario that can arise for the channel in the best possible manner. Alert transmission packets are used as a means of notification whenever a high priority node wants to transmit data. Suspend transmission packets are used to avoid priority reversal issue and a retry count is implemented to avoid starvation among the nodes
