Energy Aware Traffic Load Balancing in Mobile Networks

This chapter discusses traffic load balancing schemes that optimize network utilities, for example, average traffic delivery latency and green energy utilization. It first presents Intelligent Cell brEathing (ICE) to minimize the maximal EDRs of LBSs, thus maximizing the utilization of green energy at each stage. Then, the chapter considers a heterogeneous network with multiple MBSs and SCBSs. Both the MBSs and SCBSs are powered by on‐grid power and green energy. The chapter considers solar power as the green energy source. It focuses on balancing the downlink traffic loads among BSs by designing a green energy and latency aware user association scheme. The chapter adopts a software‐defined radio access network (SoftRAN) architecture in which all BSs are controlled by the RAN controller (RANC). It also investigates traffic load balancing in backhaul constrained cache‐enabled small cell networks with hybrid power supplies, and optimizes the BS traffic load and power distribution for mobile networks powered by smart grid.
