“…A cooperative game is played between nodes who have mutual relationship with each other while the noncooperative game is played between nodes that do not seem to coexist mutually. There have been several efforts on using noncooperative games to model security in wireless networks [9][10][11][12]. To the best of our knowledge, little work has been done in using cooperative or coalitional games to ensure security in MANETs.…”

Security in mobile ad hoc networks (MANETs) is challenging due to the ability of adversaries to gather necessary intelligence to launch insider jamming attacks. The solutions to prevent external attacks on MANET are not applicable for defense against insider jamming attacks. There is a need for a formal framework to characterize the information required by adversaries to launch insider jamming attacks. In this paper, we propose a novel reputation-based coalition game in MANETs to detect and mitigate insider jamming attacks. Since there is no centralized controller in MANETs, the nodes rely heavily on availability of transmission rates and a reputation for each individual node in the coalition to detect the presence of internal jamming node. The nodes will form a stable grand coalition in order to make a strategic security defense decision, maintain the grand coalition based on node reputation, and exclude any malicious node based on reputation value. Simulation results show that our approach provides a framework to quantify information needed by adversaries to launch insider attacks. The proposed approach will improve MANET’s defense against insider attacks, while also reducing incorrect classification of legitimate nodes as jammers.

“…where ζ k > 0 is the speed adjustment parameter of user k.A s described in [23], there always exists an upper bound for each ζ k to ensure convergence of the iterative algorithm in (6). In fact, it is possible to determine these parameters in a distributed manner, but each user must select its associated speed adjustment parameter below its upper bound.…”

Video communication over unpredictable wireless medium is a challenging research area. Many mathematical solutions have been proposed by researchers for high-quality video forwarding over such networks. An important example is the game theory. The non-cooperative game theory can be adopted to represent the selfish behaviour of network users. In the current study, a non-cooperative quality game framework (QGF) has been introduced, in which by exploiting a related quality metric, scalable video users try to enhance their perceived quality in a distributed manner in mobile ad-hoc networks. The behaviour of the Nash equilibrium point has been analysed and a distributed resource allocation strategy has been introduced. Also, the quality properties of the proposed QGF under the user churn effects have been investigated. The assigned rates in the quality game can be considered as rate-feedbacks for on-line rate adaptation of a moderate scalable video encoder such as HEVC, H.264/MPEG4 AVC etc. Some experimental results have been presented to validate the theoretical results.

“…As a branch of game theory, the non-cooperative game theory [7] can resolve the conflicts among interacting players involved in a certain game, in which each player behaves selfishly to optimize its own profit usually quantified as an objective function. The non-cooperative game can provide meaningful solutions for many applications where the inter- action among several players is negligible and centralized approaches are not suitable [8] [9]. The typical application of a non-cooperative game is the oligopoly market problem in economics, in which all corporations compete for market share of the same commodity in order to maximize their own profits [10], and the market share of each corporation tends to be stable and reaches Nash Equilibrium.…”

Dynamic Adaptive Streaming over HTTP (DASH) has demonstrated to be an emerging and promising multimedia streaming technique, owing to its capability of dealing with the variability of networks. Rate adaptation mechanism, a challenging and open issue, plays an important role in DASH based systems since it affects Quality of Experience (QoE) of users, network utilization, etc. In this paper, based on non-cooperative game theory, we propose a novel algorithm to optimally allocate the limited export bandwidth of the server to multi-users to maximize their QoE with fairness guaranteed. The proposed algorithm is proxy-free. Specifically, a novel user QoE model is derived by taking a variety of factors into account, like the received video quality, the reference buffer length, and user accumulated buffer lengths, etc. Then, the bandwidth competing problem is formulated as a non-cooperation game with the existence of Nash Equilibrium that is theoretically proven. Finally, a distributed iterative algorithm with stability analysis is proposed to find the Nash Equilibrium. Compared with state-of-the-art methods, extensive experimental results in terms of both simulated and realistic networking scenarios demonstrate that the proposed algorithm can produce higher QoE, and the actual buffer lengths of all users keep nearly optimal states, i.e., moving around the reference buffer all the time. Besides, the proposed algorithm produces no playback interruption.
