The report summarizes a study of how the consequences of follower jamming can be limited. Of particular interest is the consequences of jamming of an ad-hoc network utilizing frequency-hopping as jamming protection. To analyse the effect of follower jamming of a network a scenario is utilized. The scenario is advantageous from the jammers perspective. Results show that even at hop-rates when a part of the links in the ad hoc network is jammed, the network can be functional, i.e., the network is still connected. However, the capacity of the network will be affected. When hop-rates are reduced further some nodes lose their connections to the network. Also, at very low hop-rates, when a large part of the links is jammed, many of the network nodes can communicate with each other. This is because a number of strong links exist with a power advantage over the jammer. In addition to a frequency-hopping system with a fixed dwell-time, a system with a pseudo-random dwell-time is investigated. Similar jamming protection can be provided by the latter system at a lower average hop-rate.
