[ns] Problem sending a packet

2012-02-16 Thread David Rodenas
Hi all I'm having a strange problem when I send a unicast packet in ns-2 (I use the IEEE 802.15.4 module).  I've created a new packet type, and when the IP-destination field (HDR_IP-daddr()) is set to broadcast, the packet is received by the nodes correctly. However, when I set a specific

[ns] Problem transmitting a packet

2012-01-08 Thread David Rodenas
Hi all I am working with the IEEE 802.15.4 ns-2 implementation. I added a new packet type and I have problems when I try to send it. I define the packet, which size of payload is 8 bytes (ch-size() = 8 + IP_HEADER_LEN). Then, I populate the HDR_CMN fields like this:

[ns] HDR_CMN(p)-next_hop_ is different from the MAC destination address (p802_15_4macDA(p))

Hi all I have the following problem. I am working with the IEEE 802.15.4 Zheng's implementation in ns-2. In the routing layer I send a cbr packet where the HDR_CMN(p)-next_hop_ is set to a specific node address. However, at MAC layer, some cbr packets are not sent to that node but to another.

Hi all I have a problem with the MCPS_DATA_request primitive in the IEEE 802.15.4 ns-2 implementation. I build a new packet and send it peridically using this primitive (broadcast transmission). The thing is that this error does not always happen because I can send the packet, and it is
