In this work we consider the relay node placement problem in wireless sensor networks: where to position a limited number of available nodes that can act as additional relays to foward sensor data toward one or more base stations. The objective is to define relay node locations in order to improve network performance in terms of delivery ratio and end-to-end delay, and/or to provide connectivity in partially disconnected areas. Typical application scenarios include the repair of the network indoi:10.1109/fitce.2011.6133451 fatcat:rsf46eba5bhijgmwoolmyz2dvq
