“…Shafiee et al [6] mentioned that selecting the most appropriate access technology can depend on both user preferences, in terms of perceived QoS, cost and/or battery lifetime, among other parameters such as load balancing, interference avoidance and revenue maximization. Moon and Cho [9] presented a scheme that uplink transmit power is used as a key parameter and cells are selected on the basis of the coordination of multiple users.

In heterogeneous cloud radio access networks (HCRAN), various types of hyper-dense cells coexist and overlap with one another. Cell selection (CS), i.e., each mobile equipment (ME) always selects the most appropriate cell for access, becomes one of the key issues that have not been well solved yet. With traditional schemes, CS decision should be triggered at any time when an ME moves across any cell border. Since the deployment of femtocells in the near future will be extremely dense, an ME may quite frequently move across the border of femtocells, causing too frequent triggers of CS decisions and resulting in additional computation, signaling, energy, and latency costs. In this paper, the priorities of various types of cells are decided by cell features, ME mobility features, and application features. Since the above features change relatively slow, the priorities can be considered as static in certain period. When moving across any cell border during such a period, instead of triggering a CS decision, our scheme is to select directly the type of cells with the highest priority. Simulations show that our scheme decreases the rate of CS decisions for MEs moving in dense HCRAN scenarios.

Abstract-Supporting effective load balancing is paramount for increasing network utilization efficiency and improving the perceivable user experience in emerging and future cellular networks. At the same time, it is becoming increasingly alarming that current communication practices lead to excessive energy wastes both at the infrastructure side and at the terminals. To address both these issues, this paper discusses an innovative communication approach enabled by the implementation of device-to-device (d2d) communication over cellular networks. The technique capitalizes on the delay tolerance of a significant portion of Internet applications and the inherent mobility of the nodes to achieve significant performance gains. For delay tolerant messages, a mobile node can postpone message transmission − in a store-carry and forward manner − for a later time to allow the terminal to achieve communication over a shorter range or to postpone communication to when the terminal enters a cooler cell, before engaging in communication. Based on this framework, a theoretical model is introduced to study the generalized multihop d2d forwarding scheme where mobile nodes are allowed to buffer messages and carry them while in transit. Thus, a multi-objective optimization problem is introduced where both the communication cost and varying load levels of multiple cells are to be minimized. We show that the mathematical programming model that arises can be solved efficiently in time. Further, extensive numerical investigations reveal that the proposed scheme is an effective approach for both energy efficient communication as well as offering significant gains in terms of load balancing in multicell topologies.
