Hi everybody,
I want to add busty wireless losses to wireless channel .
I am using two state Markov model as below
#Make wireless link error model for random packet drop : two states markoverror
model没有用到
proc TwoStateMarkovErr {} {
global loss_rate
set tmp0 [new ErrorModel/Uniform 0 pkt]
set tmp1 [new ErrorModel/Uniform 1 pkt]
# Array of states (error models)
set m_states [list $tmp0 $tmp1]
# Durations for each of the states, tmp, tmp1 and tmp2, respectively
set m_periods [list 0.05 0.05]
# Transition state model matrix
set m_transmx { {0.8 0.2} {0.8 0.2} }
set m_trunit pkt
# Use time-based transition
set m_sttype time
set m_nstates 2
set m_nstart [lindex $m_states 0]
set em [new ErrorModel/MultiState $m_states $m_periods $m_transmx \
$m_trunit $m_sttype $m_nstates $m_nstart]
return $em
}
But i don't know exactly what it does and i am not getting any packet loss also.
please help me to get wireless busty losses.
Any suggestion is appreciated.
