Power saving strategies generally attempt to maximize the time that nodes spend in a low power consumption sleep state. Such strategies often require the sender to notify the receiver about pending traffic using some form of traffic announcement. Although asynchronous traffic announcement mechanisms are particularly suitable for the ad hoc environment, they also provide relatively limited power...

Energy-saving is vital in a mobile network as mobile terminals are energy contingent and is one of the most important features that extends the lifetime of portable devices. Mobile WiMAX (IEEE 802.16e) addresses the issues related to energy conservation at a Mobile Subscriber Station (MSS). In this paper, a power saving mechanism involving sleep mode operation is proposed for IEEE 802.16e netwo...

In wireless sensor network (WSN), sensors are small, inexpensive, and computable. However, they are limited in power, memory, and computational capacities. A large number of tiny sensors are usually deployed randomly to monitor one or more phenomena to collect and process the sensed data, and to send the data back to the sink. Many literatures focus on developing power-saving protocols. In addi...
