This chapter proposes a data forwarding protocol for wireless sensor networks that trades off between energy and delay. Specifically, this protocol helps achieve minimum energy consumption while ensuring uniform battery power depletion of the sensors and meeting the required delay constraints in the sense that data gathering points must receive the sensed data within a specified time bound. Given that these are conflicting goals, this trade-off is formulated as a multi-objective optimization problem whose solution is an input to our data forwarding scheme.
