“…-Concerning the energy-outage probability tradeoff, we should enlarge our study to compare the different policies with different transmission powers. For this purpose, our previous works in a multiobjective framework [23] would offer a more powerful comparison of the different strategies. -From a practical point of view, we plan to evaluate these scheme on experimental BANs to validate outage, latency, and energy models.…”

Body area networks (BAN) offer amazing perspectives to instrument and support humans in many aspects of their life. Among all possible applications, this paper focuses on body monitoring applications having a body equipped with a set of sensors transmitting in real time their measures to a common sink. In this context, at the application level, the network fits with a star topology, which is quite usual in the broad scope of wireless networks. Unfortunately, the structure of the network at the physical layer is totally different. Indeed, due to the specificity of BAN radio channel features, all radio links are not stationary and all sensors suffer from link losses during independent time frames. In wireless networks, link losses are often coped with multi-hop transmission schemes to ensure a good connectivity. However, since the radio links are not stationary, the multi-hop routes should adapt quickly to BAN changes. We instead propose in this work a different approach based on opportunistic relaying. The concept relies on electing some sensors to support the transmission of other ones having a worst connection. Instead of changing the relay time to time, we rather select a relay node from a statistical perspective. We evaluate this approach from a theoretical point of view and on realistic simulations using the packet error rate outage probability as a performance criterion.

“…If no suitable forwarding opportunity exists, the mobile nodes can store the message until such opportunity arises. The study reported in [7] showed that this store, carry and forward approach can reduce the energy consumption despite an increase in the transmission delay. The benefits of integrating MCN and opportunistic networking are discussed in [4], where the authors present novel routing policies that use information about the relays' mobility to reduce energy consumption [8], increase spatial capacity, reduce co-channel interference, balance the load across cells, and switch-off lowutilization base stations [9].…”

Multi-hop Cellular Networks can help address the increasing data demand and expected capacity constraints of cellular systems through the integration of cellular and relaying technologies. Multi-hop Cellular Networks using Mobile Relays (MCN-MR) are characterized by a decentralized and cooperative operation that provides new networking opportunities but also significant management challenges. In this context, this work investigates the use of opportunistic store-carry and forward schemes in MCN-MR networks to increase energy efficiency in the provision of delay tolerant services. In particular, the paper identifies for a two-hop MCN-MR scenario the optimum mobile relay location and the location from which the relay should start forwarding the information to the cellular base station in order to minimize the overall energy consumption. Taking this optimum configuration as a reference benchmark, the paper proposes then a scheme that relaxes the requirement to operate under the identified optimum configuration, and exploits context information provided by the cellular infrastructure. The proposed scheme is compared against other forwarding approaches, and the obtained results demonstrate the capacity of opportunistic forwarding in MCN-MR to reduce energy consumption for delay tolerant services.

“…In the absence of forwarding opportunities, mobile nodes store the message and wait for future occasions in which to forward the message to other nodes. This approach can increase the transmission delay, but it can also significantly reduce the energy consumption [10]. Simple schemes, where an SN stores and carries the information until favorable communication conditions with the destination node are found, have been shown to reduce energy consumption [11].…”

Cellular networks face significant capacity, efficiency and quality challenges because of the exponential growth of cellular data traffic. Multi-hop cellular networks (MCNs) have been proposed to address these challenges through the integration of cellular and device-to-device communications. This work investigates how the adoption and design of opportunistic store, carry and forward mechanisms in MCNs can help importantly decrease the energy consumption for delay tolerant traffic. To this aim, the study first derives an analytical framework to identify in two-hop scenarios the optimum mobile relay location and the location from which the mobile relay should start forwarding the information to the cellular base station in order to minimise the overall energy consumption. The derived optimum configuration is then used as a benchmark for the proposal and design of a novel context-based opportunistic MCN forwarding scheme that exploits context information provided at low cost by the cellular network. Numerical and simulation results demonstrate that the proposed contextbased opportunistic forwarding can achieve a performance close to that obtain with the optimum configuration and reduce the energy consumption by more than 90% compared with traditional single-hop cellular communications.
