Simulate, by using c++ ,a communication system consists of binary source, RS(7,3,5)/RS(128,122,7) encoder, BPSK modulator, AWGN channel, coherent demodulator, RS(7,3,5)/RS(128,122,7) BM decoder and sink。-Simulate, by using c, a communication system c

Simulate, by using c/c++,a communication system consists of binary source, Golay(24,12,8) encoder, BPSK modulator, AWGN channel, coherent demodulator, Golay (24,12,8)decoder and sink.

定向扩散（Directed Diffusion, DD）协议在omnet++模拟器上的实现。原理：Sink 向所有传感器节点发送兴趣(兴趣是通过分配不同的属性值来表示不同任务的描述符) , 每个传感器节点在收到兴趣后将其保存在各自的 CACHE 中。每个兴趣项包含一个时间标签域和若干个梯度域。当一个兴趣传遍整个网络后, 从 Source 到 Sink 之间的梯度就建立起来了，梯度反映了网络中节点对匹配请求条件的数据源的近似判断。一旦Source 采集到兴趣所需的数据, 那么它将沿着该兴趣的梯度路
