[ns] 802.11 ad hoc throughput papers
Hello all, I am working with ns2 to simulate a mobile ad hoc network (802.11 ad hoc mode) and I am having trouble with overloaded wireless medium. Are you aware of papers that deal with data troughput measurements for MANETs with different message frequencies and device densities (experimental or simulation)? Sincerely, Peter -- Pt!

[ns] Exponential traffic
I am trying to create an exponential traffic where packet_size should be 512, rate 250k and poisson packet rate 1 packet/10 sec . I have the following declaration for exponential traffic. What changes should I make? I tried to put 512 in packet size and left everything else the same but I get errors. Is there a CC file that I should change too? Please help me I am totally lost! proc poissontraffic { src dst interval starttime } { global ns_ node_ set udp($src) [new Agent/UDP] eval $ns_ attach-agent \$node_($src) \$udp($src) set null(0) [new Agent/Null] eval $ns_ attach-agent \$node_(0) \$null(0) set expl($src) [new Application/Traffic/Exponential] eval \$expl($src) set packetSize_ 70 eval \$expl($src) set burst_time_ 0 eval \$expl($src) set idle_time_ [expr $interval*1000.0-70.0*8/250]ms ;# idle_time + pkt_tx_time = interval eval \$expl($src) set rate_ 250k eval \$expl($src) attach-agent \$udp($src) eval $ns_ connect \$udp($src) \$null(0) $ns_ at $starttime $expl($src) start Thank you, Fani Greece ___ Χρησιμοποιείτε Yahoo!; Βαρεθήκατε τα ενοχλητικά μηνύματα (spam); Το Yahoo!
