The Network Communication Simulator (NCS) is frequently used to study the performance of a communication network. Based on the principle and requirements of the NCS, a new scheme that uses the on off matrix function to represent the network topology and bit error rate of each link is presented. In addition, a group of programmable on off matrixes is used to implement the variable network topology and detect the network state. Experimental results show that this NCS provides an effective platform for studying the performance of the Ad hoc network.
