Optimising multi-rate link scheduling for wireless mesh networks
in Computer Communications
| Description | Infrastructure Wireless Mesh Networks offer a flexible and cost-effective means to provide broadband access to premises, where instead of a direct wireless connection to a gateway to the Internet, traffic is forwarded over multiple hops between the access points of other users. To maximise the efficient use of the wireless spectrum, each access point needs to coordinate the transmissions from local clients (such as laptops, tablets, mobile devices) and the forwarded traffic from other nodes. The project has developed mathematical models of the problem of efficiently scheduling traffic within mesh networks, and developed algorithms capable of designing and coordinating schedules to optimise traffic performance. Although approximate in nature, the heuristic algorithms proposed are computationally quick yet give near optimal solutions, allowing them to be integrated into the design of network topology and routing. These outcomes have been validated on a range of benchmark problem instances, outperforming other published approaches. |

| Title | model for cycle time transmission |
| Description | we introduce a model for the optimisation of transmission schedules for infrastructure Wireless Mesh Networks in which data is forwarded through mesh routers from a single Internet Gateway node. The mesh routers receive and aggregate data from local mobile devices and each mesh router has an assigned data allowance to ensure fairness, set depending on its geographical position or the predicted usage patterns. We examined the use of fair and efficient link scheduling for Wireless Mesh Networks and provided an integer program for maximising the throughput allowance for each mesh router in a network given the topology. The model uses a slotted time approach to maximise the throughput within a given number of slots N, thus allowing the network to be split into sub networks for local access to the mesh routers, and back-haul transmissions to the gateway. |
