We address the problem of cooperative retransmission in the media access control (MAC) layer of a distributed wireless network with spatial reuse, where there can be multiple concurrent transmissions from the source and relay nodes. We propose a novel Markov decision process (MDP) framework for adjusting the transmission powers and transmission probabilities in the source and relay nodes to achieve...
With the extensive implementations of wireless sensor networks in many areas, it is imperative to have better management of the coverage and energy consumption of such networks. These networks consist of large number of sensor nodes and therefore a multi-agent system approach needs to be taken in order for a more accurate model. Three coordination algorithms are being put to the test in this paper:...
Power control for forward link soft handoff users in cellular CDMA systems is important in order to obtain good forward link performance. The two existing schemes in the 3GPP specification, balancing power control (BPC) and site selection diversity transmission (SSDT), both have shortcomings due to their static properties. In this paper, we propose a dynamic power control scheme which can modify the...
A multi-agent system (MAS) approach on wireless sensor networks (WSNs) comprising sensor-actuator nodes is very promising as it has the potential to tackle the resource constraints inherent in these networks by efficiently coordinating the activities among the nodes. In this paper, we consider the coordinated sensing coverage problem and study the behavior and performance of four distributed reinforcement...
