Cross-Layer Cooperative Delay-Energy Tradeoff Scheme for Hybrid Services in Cellular Networks

Energy efficiency is becoming an increasingly important issue in wireless networks. With the increasing diversity of types of wireless services, a user has the requirement to transmit various hybrid services simultaneously. In this paper, we propose a Cross-layer Cooperative delay-energy Tradeoff (CCT) scheme to achieve total energy consumption minimization for hybrid types of services while satisfying their quality of service (QoS) requirements in cellular networks. We exploit the enormous difference of delays and the diversity of the amounts of data between delay-sensitive services and delay-tolerant ones to conduct dynamic resource allocation. Experimental simulation results can verify that our CCT scheme can save total energy consumption of hybrid services significantly outperforming existing energy efficient schemes.
