“…In a previous work [9], we studied revenue-maximizing Radio Access Technology (RAT) selection in a Long Term Evolution (LTE) / Wireless Fidelity (WiFi) heterogeneous wireless network (HWN). The traffic with highest contribution to the revenue was granted higher priority in getting access to the network and in being served in LTE, at the expense of blocking or handing over the low-priority traffic.…”

Abstract-The net neutrality principle, also known as Open Internet, states that users should have equal access to all Internet content and that Internet Service Providers (ISPs) should not practice differentiated treatment on any of the Internet traffic. While net neutrality aims to restrain any kind of discrimination, it also provides exemption for a certain category of Internet traffic known as specialized services (SS), by allowing the ISP to dedicate part of the resources for the latter. In this work, we shed light on this particular case by comparing five Radio Access Technology (RAT) selection policies in heterogeneous wireless networks where SS traffic and Internet Access Services (IAS) traffic are carried. The studied policies include a nonnet-neutral revenue-maximizing policy used as reference policy, and four other net-neutral policies with and without exemption to SS traffic. The results show that, even though, as expected, integrating net neutrality regulation within RAT selection policies can lead to a decrease in the generated revenue, a properly designed net-neutral policy will not only be able to reduce this decrease in revenue but also can maintain a similar level of social benefit in terms of the number of users admitted to the system.

“…In addition, the results obtained from a non-net neutral revenue-maximizing RAT selection policy (introduced in [13,14]) are presented as reference. The non-net neutral policy prioritizes the admission of SS services traffic and allows the handover of IAS traffic between LTE and WiFi when there is need to free resources for SS traffic.…”

The net neutrality principle states that users should have equal access to all Internet content and that Internet Service Providers (ISPs) should not practice differentiated treatment on any of the Internet traffic. While net neutrality aims to restrain any kind of discrimination, it also grants exemption to a certain category of traffic known as specialized services (SS), by allowing the ISP to dedicate part of the resources for the latter. In this work, we consider a heterogeneous LTE/WiFi wireless network and we investigate revenue-maximizing Radio Access Technology (RAT) selection strategies that are net neutrality-compliant, with exemption granted to SS traffic. Our objective is to find out how the bandwidth reservation for SS traffic would be made in a way that allows maximizing the revenue while being in compliance with net neutrality and how the choice of the ratio of reserved bandwidth would affect the revenue. The results show that reserving bandwidth for SS traffic in one RAT (LTE) can achieve higher revenue. On the other hand, when the capacity is reserved across both LTE and WiFi, higher social benefit in terms of number of admitted users can be realized, as well as lower blocking probability for the Internet access traffic.

“…To optimize the cost, we consider dynamic state-dependent policies and apply the theory of Markov Decision Processes (MDP). MDPs have been applied for the load balancing problem in HetNets in [6], [7], [8], [9], but they do not contain any explicit forms of the resulting policies, i.e., value iteration method is used to numerically solve the problem. Also, the system models are different to ours in these papers, or energy aspects are not considered.…”

We consider optimal energy-aware load balancing of elastic downlink data traffic inside a macrocell with multiple small cells within its coverage area. The model for the problem corresponds to a system of parallel M/M/1-PS queues, where the macrocell is represented by a multiclass M/M/1-PS queue and each small cell is an energy-aware M/M/1-PS queue with additional states for the idle timer and the so-called setup delay. We apply the theory of MDPs to develop a near-optimal statedependent policy, both for a weighted sum of the performance and energy as well as for the constrained formulation, where energy is minimized subject to a constraint on the performance. Specifically, we utilize the first step of the well-known policy iteration method under which the routing decision for each arrival requires evaluating the marginal future cost of adding the arrival in the small cell or the macrocell. As our main contribution, we derive the associated value functions and the explicit form of the near-optimal FPI policy. The performance of the policy is illustrated through numerical examples.
