Wireless sensor networks are wireless mesh networks, consisting of multiple sensors. These sensors operate using batteries. They are limited in memory and computing capacity. Finally, they communicate by radio. Routing is a central problem in these networks. The authors consider here that the routing converges: i.e. there is a particular node in the network, called pit, and data from other nodes, called sources, are intended to wells. Network characteristics of wireless sensor systems are prone to attacks. They consider a critical scenario where an intruder has compromised multiple nodes.
