N2 - In this paper, we study the lifetime of a dualhop multi-relay wireless sensor network (WSN) OFDM-based system using an adaptive random relay selection strategy. In this strategy, the relays cooperate according to contribution factors associated with each relay. An analytical study of the system lifetime is presented along with simulation results. The results show that the allocation scheme guarantees fairness in allocating the resources in each relay. The results also show the impact of the number of relays on the lifetime of the WSN.
