#### 6.2.5 Number of Reached Nodes by the Coordinator  
Tables 5-7 show the number of reachable nodes by the coordinator for each of the positions of the jammer node. The column designated by the time, in seconds, presents periods of 10 s where there is an average count of how many nodes were reachable by the coordinator. The shaded rows in the tables show the times in which the attack is presented as random (\(\rho=50\) packets/s), random (\(\rho=80\) packets/s) or reactive case. As we can see, the position when the jammer node is in the middle of the topology is the one that most affects the total number of nodes that responded to the coordinator. This phenomenon may be caused due to the fact that when the jammer node being in the middle, interfering communication, it has complete circles of nodes around itself and may affect more of them. Whereas the jammer node is in one of the corners of the topology (near and far positions), it has incomplete circles of nodes; however, the far position affects fewer nodes than the nearest position. This may occur because an attack is stronger in a region with a high traffic concentration, such as the area near the coordinator node, because these nodes generate traffic and also forward traffic from other nodes to the coordinator node (destination). This causes a larger amount of collisions, and this can be increased if there is an attack present.
