BLAM: An Energy-Aware MAC Layer Enhancement for Wireless Adhoc Networks

Overview In wireless adhoc networks channel and energy capacities are scarce resources. However, the design of the IEEE 802.11 DCF protocol leads to an inefficient utilization of these resources. This paper introduces BLAM, a new Battery Level Aware MAC protocol, which is developed from an energy-efficiency point of view to extend the useful lifetime of an adhoc network. The paper modifies the IEEE 802.11 DCF protocol to enable BLAM to dynamically tune the transmission probability and the random deferring time for fresh and collided data packets based on the node's current relative battery capacity.

Intel hit with energy-efficiency patent suit

It claimed its Crusoe processors would be able to run the same software as Intel chips but gobble up less electricity, thus leading to longer battery life. The patents relate to power efficiency. Transmeta, the chip designer that once tried to take...

RIM quiet on touchscreen BlackBerry rumours

He said: "We focus principally on the efficiency because you have a multi-variant scarcity equation: battery is limited, thermodynamics is a challenge, capacity of the network is a challenge, size is a challenge - I have but one belt to give and I...

Minority Report: What's in store for the iPhone?

It also included the interesting system message: "Using 3G loads data faster but decreases battery life. One of the reasons Apple stated it hadn't put the 3G chip in the first iteration was battery life.

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?

Telecom 2.0: Mind over matter

ntl:Telewest Business believes that the role of the telco is evolving. Gone are the days when it was enough to simply focus on circuits and minutes, customers now need a far higher degree of interaction and look for suppliers who will talk business solutions with them.
