The hidden node simulation under ns2.35
4.0
The purpose of the experiment - master the essence of the hidden node problem The hidden node problem - the use of NS2 simulation 2 experimental background The hidden node refers to in the coverage of the sending node external nodes in the coverage of the receiving nodes in. Due to listen to not to send the sending node, the hidden node may be transmitted to a receiving node grouping the same, lead to packet at the receiving node conflict. Hidden nodes can be divided into a sending node and the receiving node of hidden hidden. Such as teaching eightieth page shown in Figure 3.17, the node A and C also wants to send data to the node B, but A and C are not in the transmission range of each other within the. So when A sends data to the B, C was not detected in A is to send data, think in the current network data transfer, data will be sent to the B. In this way, A and C and sends the data to B, making data conflict in B, eventually leading to send data is not avai
