IRMA: Integrated Routing and MAC Scheduling in Multi-Hop Wireless Mesh Networks

Overview This paper presents an Integrated Routing and MAC scheduling Algorithm (IRMA) for improving system performance in multihop wireless mesh networks. The IRMA approach is motivated by the fact that conventional contention-based MAC protocols such as 802.11 do not perform well in combination with independent ad hoc routing protocols such as DSR, DSDV or AODV due to interactions between neighboring nodes in the network. In IRMA, a centralized algorithm is used to allocate resources to each flow based on traffic flow specifications and the network compatibility graph based on a generalized n-hop interference model. Joint routing and MAC eliminates contention between radio nodes and assigns traffic flows to alternate paths based on actual traffic demand, thereby providing significant increases in network capacity.

RFID-tagged driverless cars on roads by 2056

The report said: "Vehicles will incorporate hundreds of network nodes to manage fuel efficiency, security, passenger monitoring and passenger comfort, as well as inter-vehicle distances and optimal vehicle speeds.

Radioactive: Today a jam, tomorrow the open road?

The routing algorithm is based on the position of the vehicles and is able to handle the typically fast changes of ad hoc networks. The intention is to develop a set of standards for frequency, authentication and communications that will allow two...

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?
