Description: 纯ALOHA协议
在该协议下，用户只要有帧产生，就会传送出去，发生冲突时，就等待一个随机时间后再重发。
所以对当前帧时，只有两种情况下可以发送成功：
1）当前帧时只有一帧要发送，且当前帧时的前一帧时无帧发送；
2）当前帧时只有一帧要发送（发送时刻为t），且前一帧时的最后一帧的发送时间不在（t- FRAMETIME）~ t这段时间内。
其他情况下都会产生冲突。
发生冲突时，错误帧继续传送，用户重新发送帧，设定一个随机数Rt，将该帧添加到第Rt/ FRAMETIME帧时上去，并设该帧的相对时间为Rt% FRAMETIME。这样即相当于用户等待一随机时间后重发。
对每一帧时进行上述控制，最终可得到成功发送的次数Suc，将其除以Suc = Suc /ARRAYLENGTH即得平均每帧时发送成功的帧数。
对于不同G，得到不同FrameArray，所得的Suc也不同，用一个数组来保存G与Suc的对应关系，再将其画出来。
-pure ALOHA agreement under the agreement, as long as users have a frame, it will transmit out, conflict, will wait for a random period of time before re-issued. Therefore, the current frame, there are only two circumstances can this success : 1) the current frame only one to send, and the current frame before one-time frame sent; 2) the current frame only to send a (t this moment), but before a final of a transmission time not (t-FRAMETIME) ~ t this time. Other cases will have conflict. Conflict, to continue to disseminate the wrong frame, users re-sending frames, set a random number Rt, this frame added to the first Rt / FRAMETIME frames up, and established the time frame for the relative% FRAMETIME Rt. This is equivalent to that user for a random period of time after re-issued. For each

Description: 初学者，自己刚编写好的saloha程序代码，也是由aloha例程改编来的，添加了时隙控制和常规中断。看到论坛里有其他人的saloha，不清楚他们是怎样写的，如果同时都是时隙aloha，站长可以通过么-The slot aloha OPNET program by myself according to the aloha code.Using regular interrupt.Now there have been similar code here,I don t know how others to coding it.
