MIMO based MANET has received a great deal of attention in the past decade, resulting in a number of MAC layer protocols that aim to utilize the inherent capabilities afforded by multi-antenna enabled nodes. Many of these MAC protocols look to improve on the total number of concurrent links within the network. In this paper, we present a theoretical approach for identifying the maximum number of concurrent...
As wireless systems continue to proliferate, interference management is becoming a concern in both military and commercial domains. This paper introduces a novel cognitive coexistence framework between infrastructure and ad hoc networks. Based on sensing and predicting the ad-hoc networkpsilas activity, the infrastructure system allocates power and transmission time such as to minimize its impact...
Game theory is a useful tool that can be used to study the distributed resource allocation problem, since each node in the network tries to maximize his own payoff and hence a need to resolve their conflicting interests. In this paper, we introduce utility functions so that the strategy set of each node allows no transmission. We incorporate the effect of interference a node is causing to the surroundings...
This paper addresses the adaptive allocation of subcarrier, bit and power resources in the downlink of multicell OFDMA systems, where base stations allocate radio resources in a decentralized manner. Our algorithm uses discrete bit-loading values which is more applicable to the practical systems. Noncooperative game theoretic approach is adopted and we first only include the transmit power and throughput...
This paper presents optimal channel assignment algorithms to maximize the unicast network capacity of large scale multi-channel, multi-radio, multi-hop static wireless networks under the Arbitrary Network model and the Random Network model, respectively. The network capacities are approximated by the network capacity bounds derived in the literature and the optimization problems are formulated and...
