[ns] about packet modify in MAODV protocol
hi, i want to modify the RREP message packet in MAODV. i add one variable and one array in the packet as below : struct hdr_aodv_reply { u_int8_trp_type;// Packet Type /*** modified for multicast ***/ //u_int8_treserved[2]; u_int8_t rp_flags; u_int8_treserved; /***/ u_int8_trp_hop_count; // Hop Count nsaddr_trp_dst; // Destination IP Address u_int32_t rp_dst_seqno; // Destination Sequence Number nsaddr_trp_src; // Source IP Address double rp_lifetime;// Lifetime double rp_timestamp; // when corresponding REQ sent; /add for me/ double rp_S; nsaddr_t rp_pt[5]; /**/ inline int size() { int sz = 0; /* sz = sizeof(u_int8_t) // rp_type + 2*sizeof(u_int8_t)// rp_flags + reserved + sizeof(u_int8_t)// rp_hop_count + sizeof(double) // rp_timestamp + sizeof(nsaddr_t) // rp_dst + sizeof(u_int32_t) // rp_dst_seqno + sizeof(nsaddr_t) // rp_src + sizeof(u_int32_t); // rp_lifetime */ sz = 6*sizeof(u_int32_t)+sizeof(double)+5*sizeof(nsaddr_t); assert (sz = 0); return sz; } the error is :segmentation falt (core dumped) thanks for help me.

[ns] how to control CBR packets transmitted on different route
hi, supposed that there are two routes betwen node a and d, one through b ,and the other through c. that is, the first route is a-b-d, and the send route is a-c-d. how can i send the different CBR packet on the differnt route. for example, i want send packets whose packet_id=1,3,5,7,...on the first route, and the packets whose packet_id=2,4,6,...,on the sencond route. thanks your help. hujie
