This work is part of a research project that analyzes and develops efficient technologies for street lighting systems, and it describes a wireless sensor network system used for controlling and monitoring electrical variables. The street lighting system is composed by an urban network, where delivery rate (with priority related to other aspects), latency, energy efficiency, and fault tolerance are the non-functional requirements. Based on these requirements, this work presents a new network routing mechanism with acknowledgment, named GGPSR. The main purpose is to provide new means to reach high delivery rates in urban networks, with tolerated end-to-end delay values for this type of network. The mechanism consists of selecting nodes from neighbors others than the previously selected in order to find a path towards the destination. Simulation results demonstrate the algorithm fulfills the mentioned requirements.
