Abstract-Direct device-to-device communication based on the 'store-carry-forward' paradigm is considered a feasible means for offloading mobile data traffic. Employing device-to-device communication however should satisfy user demand without greatly affecting battery lifetime. In order to provide satisfactory application throughput it is often assumed that nodes behave altruistic, and are willing to share contents for an infinite amount of time. In the context of energy savings, this assumption is overly optimistic. This work evaluates the performance of a publish/subscribe opportunistic content dissemination application that uses duty cycling for energy saving and allows nodes to behave in a selfish manner. Two types of selfishness are introduced: strict and mild. The paper presents the impact of selfishness on both application throughput and energy consumption via extensive trace-driven simulations, and demonstrates that introducing strictly selfish behavior on top of duty cycling leads to great decrease in energy consumption (up to 90% in certain cases) without causing significant loss in application throughput. Moreover, when the duration of the mild selfishness interval is chosen appropriately, mild selfishness can lead to even further decrease in energy consumption while at the same time increasing the application throughput.

“…Lu et al [26] and Zhao et al [8] propose incentive schemes for promoting altruism in opportunistic networks, however neither of the works discusses the implications, in terms of energy consumption, of altruistic behavior in battery powered devices. Ciobanu et al [9] devise a mechanism for detecting and avoiding selfish nodes throughout the routing process in opportunistic networks. In contrast to all mentioned studies, we promote selfishness in opportunistic networks used for mobile data offloading in order to decrease the energy consumption of participating devices.…”

“…This may be an overly optimistic assumption, and nodes that have already obtained all contents of interest may prefer to opt out of distribution in order to save energy. By default, selfishness has always been considered harmful to the performance of opportunistic networks and different mechanisms have been suggested for providing incentives for nodes to behave altruistic [8], as well as for detection and avoidance of selfish nodes throughout the routing process [9]. However, they do not take into account the price in terms of energy consumption that a node pays for being altruistic.…”

Abstract-Opportunistic networking (a.k.a. device-to-device communication) is considered a feasible means for offloading mobile data traffic. Since mobile nodes are battery-powered, opportunistic networks must be expected to satisfy the user demand without greatly affecting battery lifetime. To address this requirement, this work introduces progressive selfishness, an adaptive and scalable energy-aware algorithm for opportunistic networks used in the context of mobile data offloading. The paper evaluates the performance of progressive selfishness in terms of both application throughput and energy consumption via extensive trace-driven simulations of realistic pedestrian behavior, and demonstrates that the proposed algorithm is robust against the distributions of node density and initial content availability. The results show that in certain scenarios progressive selfishness achieves up to 85% energy savings during opportunistic downloads while sacrificing less than 1% in application throughput. Furthermore, the study demonstrates that in terms of total energy consumption (by both cellular and opportunistic downloads) in dense environments the performance of progressive selfishness is comparable to downloading contents directly from a mobile network.

“…The authors proposed a novel approach based on an ant colony algorithm to enhance the efficiency and to diminish the overhead. Ciobanu et al [18] suggested an incentive mechanism for detecting selfish nodes in opportunistic networks. The aim of this approach was to diminish the issues of having selfish nodes in an opportunistic network.…”

A mobile ad hoc network (MANET) is a self-organized system comprised by multiple mobile wireless nodes. The node misbehavior due to selfish reasons can significantly diminish the performance of MANET. A selfish node attempts to use the resources only for its own purpose and it hesitates to share the resources with their neighbors. So, it is very important to detect the selfish nodes to improve the performance of MANET. Initially, an architectural model of a MANET is constructed and the communication between the mobile is originated. The packet drop can happen in MANET due to the selfish node or network congestion. In this paper, a Record-and Trust-Based Detection (RTBD) technique is proposed to detect the selfish nodes efficiently in MANET. The main reason for using trust in this analysis is to accelerate the detection of misbehaving nodes. This study has been carried out in order to analyze the detection of selfish nodes on essential network functions such as routing and packet dropping. The results show that the proposed selfish node detection method is very efficient, since the detection time of selfish nodes is diminished and the overall overhead is very low. The simulation study demonstrates that the proposed RTBD method enhances the selfish node detection ratio, packet delivery ratio (PDR), and average packet drop ratio.
