Due to the rapid increase in the usage and demand of wireless sensor networks (WSN), the limited frequency spectrum available for WSN applications will be extremely crowded in the near future. More sensor devices also mean more recharging/replacement

This paper provides a relaxation of the sufficient conditions and an extension of the structural results for partially observed Markov decision processes (POMDPs) obtained by Lovejoy in 1987. Sufficient conditions are provided so that the optimal pol

Healthcare facilities with intelligent wireless devices can reduce the workload of the paramedic staff. These devices include low-power wireless sensors, personal wireless hub (PWH), and receivers. The PWH can act as a relay in the hospital network.

In this paper, we study a cognitive radio network comprising a pair of sources and multiple relays operating in non-overlapping bands in the radio spectrum. We address the problem of deciding the transmission powers of the sources and relays so that

In this work, we consider a cognitive radio network comprising a pair of sources and multiple relays exercising the amplify-and-forward cooperation in a shared frequency band. For such a network, we consider the problem of determining transmit powers

The use of multiple relays can increase the performance of a cooperative communication system. A well-designed multiple-relay-assignment and power-allocation scheme can be helpful in reducing interference induced to primary users (PUs) in a cognitive

In this paper, we apply the binary particle swarm optimization to the problem of selecting sensors from a set of sensors for the purpose of minimizing the error in parameter estimation. The motivation of selecting sensors rather than utilizing all se
