  Many wireless protocols wait a small and random amount of time which is
called jitter before sending a packet to avoid high contention and packet
collision. Jitter has been already proposed for many routing protocols
including AODV and LOADng. However, since they do not consider any link quality
parameters or metrics (such as ETX) in routing, they fail to be efficient in
metric-based routing protocols. A metric-based jitter mechanism is proposed in
this paper and a closed form expression is derived that enables us to obtain
the probability of delay inversion for all jitter mechanisms available.
Simulation results are also presented to show the performance of different
jitter mechanisms.
