Abstract:
The research of the transmission capacity in wireless Ad Hoc networks based on bidirectional channels grew slowly. The closed-form expression could not be obtained. As a result, the relationship between the transmission capacity and the network parameters could not be expressed exactly. To sllve the problem, the system model of bidirectional transmission in wireless Ad Hoc networks, was proposed to redefine the bidirectional transmission capacity based on the symmetrical bidirectional transmission channel, and to derive the probability of successful transmission and tranmission capacity for bidirectional transmission. Numerical results showed that, the probability of successful transmission for single transmission was affected by some network parameters, and was mainly determined by the density of transmission pair with which the probabilityof successful transmission would increase. The bidirectional transmission capacity was mainly determined by the maxinum outage probability. When the maximum outage probability was a small value, the bidirectional transmission capacity would increase with maximum outage probability, while the quality of communicationwould reduce, so how to choose a suitable maximum outage probability was very important in real networks.
