Parallel MAC protocol based on geographical location information and power control in ad hoc networks
The conflict interference produced by the parallel transmission of the exposed nodes was investigated,and a parallel MAC protocol based on geographical location information and power control in ad hoc networks was proposed.This protocol identified the exposed nodes by their geographical location inf...

| description | The conflict interference produced by the parallel transmission of the exposed nodes was investigated,and a parallel MAC protocol based on geographical location information and power control in ad hoc networks was proposed.This protocol identified the exposed nodes by their geographical location information and introduced the power control mechanism into the parallel transmission of the exposed nodes.When the probability of the successful parallel transmis-sion was low,the protocol reduced the parallel transmissions by using the random backoff mechanism,thus avoided the interference caused by the failed parallel transmission and the energy consumption of the nodes.The simulation results show that,compared with the DCF protocol,this new protocol can improve the average throughput of the network sig-nificantly and save the average energy consumption of the nodes simultaneously,thus prolong the lifetime of the nodes and the network. |
