Energy saving is seldom contemplated in cellular railway communication network because safety is always the main focus. However, we analyzed train schedules and determined that the cellular railway network had...
Due to the complexity of multi-band orthogonal frequency-division multiplexing (MB-OFDM), achieving low power is still one of the major difficulties in designing the MB-OFDM-based ultra wideband (UWB) receiver...
The last decades have been really hungry in new ways to reduce energy consumption. That is especially true when talking about wireless sensor networks in general and home multimedia networks in particular, sin...
In a cognitive radio network (CRN), when the secondary users (SUs) are battery-powered devices, the concept of energy-efficient design is very important. The sensing time and the number of cooperative SUs in t...
Wireless sensor networks (WSNs) could potentially help in the measurement and monitoring of noise levels, an important step in mitigating and fighting noise pollution. Unfortunately, the high energy required b...
This paper addresses energy-efficient design for uplink multiuser SIMO systems with imperfect channel state information (CSI) at the base station (BS). Since the CSI at the BS is always imperfect due to the ch...
It is easy for adversaries to mount node replication attacks due to the unattended nature of wireless sensor networks. In several replica node detection schemes, witness nodes fail to work before replicas are ...
Network security and its energy efficiency are facing tougher challenges for mobile ad hoc networks (MANETs) due to emerging purposive strategic internal attacks conducted by smart malicious nodes and unavoidable...
Ad hoc networks are wireless mobile networks that can operate without infrastructure and without centralized network management. Traditional techniques of routing are not well adapted. Indeed, their lack of re...
Cloud computing is a style of computing in which dynamically scalable and other virtualized resources are provided as a service over the Internet. The energy consumption and makespan associated with the resour...
Coverage problem is an important research topic in the field of wireless sensor network (WSN). The coverage algorithm based on event probability driven mechanism (EPDM) is put forward in this paper. First of a...
Monitoring the illegal movement across national border effectively is a challenging problem. The emerging technology of wireless sensor network (WSN) is expected to provide a new way to realize energy-efficien...
