Joint mode selection and link allocation for Device-to-Device (D2D) communications underlaying cellular networks are essential to improve users' energy efficiency. Meanwhile, mobile terminals are held by human beings, who may formulate social relationships to enhance users' cooperation in spectrum resource sharing. In this work, a novel optimization framework based on coalition formation game theory...
Coalitional Game Theory augurs to become a remarkable utility as an analytical and design tool for the needs of dynamic, scalable and autonomous networks. This paper demonstrates the efficacy of applying Dynamic Coalition Formation game in relay assisted spectrum sensing in cognitive radios.
Advertising among vehicles has become popular with the proliferation of vehicular ad-hoc networks (VANETs). Since the price of the advertisements broadcast in such networks decay over time, distributing advertisements with a high price value to more private vehicles can generate more revenues to the sellers. In this paper, we consider a bus-based priced advertising scenario in a VANET, in which the...
In Machine-to-Machine (M2M) communication networks, the signalling congest and complexity for resource allocation is becoming one of the most important problems that should be dealt with the increasing of network scale. In this context, a clustering transmission strategy for the large-scale M2M networks has been proposed in this paper. To make the scheme can be carried out in distributed way, a joint...
To decrease search time in P2P network, there have been many researches on overlay construction, specifically by clustering peers into semantic groups. Although environment may change dynamically over time, the process of clustering is predetermined and static in most of these researches and doesn't address issues related to dynamic solution concepts. This leads to undesired increase of network traffic...
Delay tolerant networks (DTNs) can be composed of multiple heterogeneous groups (i.e., communities) of nodes. The nodes from these communities can cooperate with each other in order to carry and forward data packets so that the performance (e.g., delay) can be improved. However, this cooperation will incur additional cost on the nodes. In this paper, we first develop an analytical model to investigate...
In current peer-to-peer file sharing networks, a large number of peers with heterogeneous connections simultaneously seek to download resources, e.g., files or file fragments, from a common seed at the time these resources become available, which incurs high download delays on the different peers. Unlike existing literature which mainly focused on cooperative strategies for data exchange between different...
Due to the constrained energy, energy efficiency becomes the primary objective in the design of wireless sensor networks, where extending network lifetime is considered as one of the energy efficient techniques. In addition, the advantage of the cooperative MIMO scheme over the non-cooperative SISO scheme doesn't always exist, if considering the cost in term of the addition overhead. So we should...
We formulate the sensing-throughput tradeoff problem for distributed cognitive radio (CR) networks as a coalition formation game. Formation of coalitions enables the CRs to increase their achievable throughput, under the detection probability constraint, while also taking into account the overhead in sensing reports combining. In the proposed game, CRs form coalitions either to increase their individual...
