A lot of access points (APs) in wireless mesh networks (WMNs) are battery powered. In order to minimize their energy consumption, the APs can adaptively adjust their transmission power and time based on various network conditions. In this paper, the problem of minimizing the AP energy consumption is formulated as an optimization problem with the constraint to satisfy the throughput requirements of...
The growing concern of global climate change calls for a revolutionary change on the way of utilizing the energy. In terms of the ICT industry, energy efficiency needs to be considered as an important metric to evaluate a communication system, besides the conventional metrics such as quality of service, bandwidth efficiency, etc. Research should be done to raise the energy efficiency of communication...
Throughput and energy efficiency are two important parameters to evaluate the performance of a wireless sensor network (WSN). For WSNs involved in varying channel conditions packet transmission reliability can be affected. This results in increased number of retransmissions and therefore energy consumption, with low throughput. Making optimal choices for robust packet transmission in this scenario...
A high efficient random number generators (RNGs) in simple structure with period 2k-1 is presented, where k is the multiple of 32. Software implementation of these RNGs only require few fundamental instructions, such as XOR operations and circular rotation operations, as a result that they have a very high software efficiency and low memory consumption compared to some other RNGs. Meanwhile due to...
