In this paper, we propose the optimal resource allocation strategies for energy constrained coded cooperative networks. By combining power control and multi-relays selection with LOC adjustment, our schemes aim at providing higher QoS and extending network lifetime. We consider the TDMA based scenario where one node acts as the source and the other nodes can be selected as relay nodes in a time slot and each node is limited by separate power constraint. Firstly, we build an optimization model for minimizing and balancing the energy consumption under QoS constrains. After that, when the LOC is constant, a closed form optimal solution is got by KKT conditions, which results in a dynamic resource allocation strategy. Moreover, based on solution for the fixed LOC, a suboptimal scheme is further proposed for a variable LOC via one dimension searching. The simulation results show that our schemes can improve network QoS and prolong network lifetime dramatically comparing with other existing cooperative resource allocation schemes.
