Security in wireless sensor networks

Paper in proceeding, 2012

A wireless sensor network is a network of small computers, sensor nodes, that can gather information via its sensors, do computations and communicate wirelessly with other sensor nodes. In general a wireless sensor network is an ad hoc network in which the nodes organize themselves without any preexisting infrastructure. Once in the area, the nodes that survived the deployment procedure communicate with the other nodes that happened to end up in its vicinity, and they set up an infrastructure.
