This work addresses the problem of deriving fundamental trade-off bounds fora 1-relay and a 2-relay wireless network when multiple performance criteria areof interest. It proposes a simple MultiObjective (MO) performance evaluationframework composed of a broadcast and interference-limited network model;capacity, delay and energy performance metrics and an associated MOoptimization problem. Pareto optimal performance bounds between end-to-enddelay and energy for a capacity-achieving network are given for 1-relay and2-relay topologies and assessed through simulations. Moreover, we also show inthis paper that these bounds are tight since they can be reached by simplepractical coding strategies performed by the source and the relays. Twodifferent types of network coding strategies are investigated. Practicalperformance bounds for both strategies are compared to the theoretical upperbound. Results confirm that the proposed upper bound on delay and energyperformance is tight and can be reached with the proposed combined source andnetwork coding strategies.
