Wireless Sensor Networks (WSN) are composed of constrained devices and deployed in unattended and hostile environments. Most papers presenting solutions for WSN evaluate their work over random topologies to highlight some of their \"Good\" performances. They rarely study these behaviors over more than one topology. Yet, the topology used can greatly impact the routing performances. This is what the authors demonstrated in this paper. They present a study of the impact of network topology on algorithms performance in wireless sensor networks and illustrate it with geographic routing. Geographic routing is a family of routing algorithms using nodes coordinates to route data packet from source to destination.
