“…3 In this work, we assume the transmission rate of a relay is fixed, which is determined by the packet size and length of the time slot. 4 In the simulations in Section V, p is calculated based on the real distance between node i and node j and the Rayleigh fading model. The simulation results show that our strategy designed with approximation can work efficiently in real scenarios.…”

“…Examples include the Internet Protocol Television (IPTV) over WiMax [1] and multimedia broadcast/multicast service (MBMS) in 3G networks [2], [3]. To combat channel fading, cooperative multicast has been shown as an effective technique to provide reliable multicast service in wireless networks [4]- [11], where successful nodes are selected as relays to rebroadcast the data. In most of the existing cooperation strategies, it is assumed that nodes will cooperate unconditionally, and always forward data when selected as relays.…”

Cooperative multicast is an effective technique to provide reliable multicast service in wireless networks. However, selfish nodes may act as free riders to maximize their payoffs, and an incentive mechanism is needed to stimulate cooperation. In this paper, we employ a game theoretic approach to analyze the interactions among selfish mobile nodes in wireless multicast networks. The cooperation process is modeled as an infinite repeated game and the desired cooperation state that achieves absolute fairness and Pareto optimality is derived. A Worst Behavior Tit-for-Tat (WBTFT) incentive strategy is proposed to stimulate cooperation at the desired cooperation state. In the proposed strategy, a node monitors others' behaviors and makes decisions according to the worst behaved node. With perfect monitoring, we analyze the conditions for the proposed strategy to be subgame perfect. To address the issue of imperfect monitoring, an interval based estimation method is proposed and the subgame perfect equilibrium conditions are derived under the assumption that nodes are bounded rational. Simulation results show that the proposed strategy can efficiently enforce cooperation even with imperfect monitoring, and its performance is close to that when all nodes fully cooperate with each other and when they can perfectly monitor each other's behavior without errors.

In this paper, we develop an effective inter-cell interference coordination (ICIC) scheme for co-channel interference in downlink orthogonal frequency division multiple access (OFDMA) networks through cognitive sensing performed by subnet nodes in heterogeneous network (Het-Net). The more co-channel interference is detected and avoided, the more power is saved for both macro BS and subnet nodes. The strategy framework of the cognitive critical ratio and the number of subnet nodes is set up for interference management aiming at maximizing net saving power for the whole system. The framework is modeled as multiple objective non-linear programming (MONLP), employing parallel vector evaluated particle swarm optimization algorithm (VEPSO) to obtain the global optimum solution. Utilizing dynamic traffic loads, we could figure out the optimal deployment of low-power BSs. Finally, the practical implementation in Het-Net for long term evolution advanced (LTE-A) is designed. The numerical evaluation and system simulation results demonstrate the applicability and effectiveness of the proposed interference management framework.

“…For adopting relay scheme to the broadcast/multicast, the authors design the distributed relay node selection algorithm which helps choosing the relay nodes among good channel nodes efficiently. In [2], a group-based relay approach for multicast services is proposed for relay-based emergency communications and two ARQ-enabled techniques are discussed to improve the reliability of multicast and broadcast services. Also, a cross-layer auto rate selection multicast mechanism capable of adapting the data transmission to the varying conditions of the channel is introduced in [3].…”

A reliable transmission scheme for security and protection system (SPS) based on internet of things is proposed. A cooperative transmission mechanism is designed to improve the reliability and efficiency of data services. Meanwhile, rate selection algorithm based on channel conditions is elaborated. An analytical model is introduced to evaluate performance of our proposed cooperative broadcast scheme. Simulation results indicate that the proposed scheme can significantly improve throughput performance compared to conventional scheme.
