In this paper, by changing their internodes distances, the authors compare the performance of Mobile Ad hoc NETwork (MANET). In this paper, they compare protocols DSR by using changing their internodes distances. They know that in ad hoc network, they communicate node by node by using interconnect network without any infrastructure. In ad hoc network each node works as a router. Each node having Wi-Fi capability for transfer the packets between each node or node by node. In case of mobile ad hoc network nodes can change the position.
