In this paper, we focus on collision probability analysis in multi-hop ad hoc networks. We first introduce the concepts of RTS frame collision range and Data frame collision range, and then we propose a bidimensional Markov chain model to mimic the behavior of the binary slotted exponential backoff (BEB) procedure in IEEE 802.11 MAC protocol. In this model, we put forward the pseudo states to distinguish...
Recently, there has been a clear trend towards the application of the ad hoc networking technology in the civil aviation communication system, and then a novel research field of aeronautical ad hoc networks (AANET) has arisen. Researchers have showed that it is possible to set up a mobile ad hoc network among the free flight airliners, thus providing a multi-hop communication link between the airliner...
In this paper we focus on the concept of IEEE 802.11 DCF error frame model. Based on the analysis of the model in detail, we point out the error of the simulation algorithm of the DCF error frame model in QualNet simulation environment. Furthermore, we modify the simulation algorithm in QualNet strictly according to the specifications of the DCF error frame model. The simulation results show that...
