Data gathering is a fundamental task of wireless sensor network (WSN). Recently, mobile sink has been exploited for data gathering in WSN to reduce and balance energy expenditure among sensors. How to energy-efficiently collect and transmit the data in case of multiple mobile sinks is a hot research topic. In this paper, we propose a multiple mobile sinks energy-efficient data collection (MSE2DC)...
Recent, mobile sink has been exploited for data gathering to reduce and balance energy expenditure among sensors. Most of previous works are dedicated to look for a shortest path to the mobile sink regardless of the heavy signaling overhead and high latency caused by the frequent updating of topology and routing. Moreover, in most use cases, there is no necessary to frequently collect data from the...
3GPP Release 8 specifications define a mechanism named DRX (Discontinuous Reception) to save UE’s (User Equipment) energy consumption in LTE (Long Term Evolution). The DRX allow an UE to stop monitoring PDCCH (Physical Downlink Control CHannel) on a CC (Component Carriers) during some periods of the operation time. Obviously, the duration and the frequency of these non-monitoring periods are important...
