Several review papers [17, 18] discuss MTC in 3GPP LTE/LTE-A networks, introduce M2M use cases in detail, and identify the challenges with regard to M2M over LTE/LTE-A, e.g., random access congestion, resource allocation with QoS provisioning.
The heavy memory access of motion estimation (ME) execution consumes significant power and could limit ME execution when the available memory bandwidth (BW) is reduced because of access congestion or changes in the dynamics of the power environment of modern mobile devices.
"The telematics industry needs standardisation and access to congestion data so we can develop commercial services like traffic management and in-car navigation systems.
A Home Office document, released to the press, apparently by mistake, reveals that legislation is being prepared to grant police access to congestion charging and traffic flow information, as a matter of course.
The issues cover medium access control, congestion control, service differentiation, and admission control in generic BWA and IEEE 802.16 WirelessMAN (or WiMAX).
Now, it would be straightforward to vary the price of online access depending on congestion and build an app that let bargain hunters shift their activities to cheaper periods, even on a minute-by-minute basis.
To address random access channel (RACH) congestion and high signalling overhead problems of machine-to-machine (M2M) communication in cellular networks, we propose a new design of a random access procedure that is engineered exclusively for the M2M communication.
Transit services (e.g., public bus service) are a component of the overall park transportation system and are very desirable in park settings as they yield many advantages over personal auto access including reduced congestion in parking areas, a reduced carbon footprint, and an enhanced visitor experience.
He said the school had made referrals to police who were taking action and had written to parents to tell them there was a preferred collection point on a safer road with better access and less congestion.
The ULED introduced more stringent emission standards that limit the free access to the congestion charge zone to all-electric cars, some plug-in hybrids, and any car or van that emits 75g/km or less of CO2 and meets the Euro 5 emission standards for air quality.
Controlling for factors such as income and working at home, we find that the effects of congestion on access depend on whether congestion-adaptive travel choices (such as walking and making shorter trips to nearby destinations) are viable.
