Minimum latency data aggregation scheduling in MR-MC wireless sensor networks by Jin-bao LI, Meng WANG, Long-jiang GUO

“…The problem of minimum latency data aggregation scheduling in single-radio single-channel wireless sensor networks is a NPC problem and many solutions have been proposed.In multi-radio multi-channel networks,the latency may be lower as a node may receive transmission data from other different nodes simultaneously.It formulates the minimum latency data aggregation scheduling into an optimization problem with joint consider of tree structure,time slot assignment,channel assignment and radio assignment.The problem is divided into constructing data aggregation tree and designing a node schedule subproblems.For each subproblem,heuristic algorithm has been proposed.The simulation results show that the proposed algorithm achieve good performance.…”

Design and Performance Analysis of a Novel MAC Protocol for Full Duplex Wireless Network by Hongzhi Mo

“…Two independent frequency bands are used for half duplex radios to realize simultaneous transmission and reception.Recently，full duplex radios are allowed to transmit and receive data packets simultaneously in one frequency band.To improve the performance of full duplex radio networks，a novel MAC protocol called FD-MAC for full duplex radio networks，which was a simple and efficient protocol compatible with standard IEEE 802.11 MAC protocol，was proposed.By taking both the physical layer and MAC layer into account，the performance of full duplex network with FD-MAC was analyzed.The analytical and simulation results demonstrate that，compared with the existing MAC protocols for full duplex radio，FD-MAC protocol owns a higher network throughput performance and a lower power consumption.…”
