In this book we have research on performance evaluation of two proactive routing protocol (DSDV and I-DSDV) with or without internet protocol version 6 and the black hole attack. we have to use three parameter for the better results in proactive routing protocols. The simulation results in MANET is done with network simulator version 2 (NS2).The improved DSDV protocol can reduce the number of dropped data packets without any new message exchange especially in black hole and ipv6.
