Embodiment Construction
[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0038] Such as figure 1 As shown, the relay selection method based on interrupt priority in the single-source multi-relay cooperative communication system provided by the present invention includes the following steps:
[0039] Step 1: On the destination node, set the forwarding times counter for each relay in the system to count the number of times the relay participates in the cooperative communication, and set the initial value of the forwarding times counter of each relay to be zero, that is For the mth relay (m∈{1,…,M}), set cnt m =0, where cnt m is the value of the forwarding times counter of the mth relay, and M is the total number of relays in the system;
[0040] Step 2: The cooperation period starts. After the source node broadcasts data, observe the channel quality of all links, select the relay whose channel capacity is greater than the interru...
