Mobile edge computing (MEC) is expected to provide low-latency computation service for wireless devices (WDs). However, when WDs are located at cell or communication links between base stations (BSs) and blocked, the offloading latency will be large. To address this issue, we propose an intelligent reflecting surface (IRS)-assisted cell-free MEC system consisting of multiple BSs IRSs improving transmission environment. Consequently, formulate a min–max optimization problem by jointly...

Comprehensive Summary Near‐infrared (NIR)‐absorbing polymerized small molecule acceptors (PSMAs) based on a Y‐series backbone (such as PY‐IT) have been widely developed to fabricate efficient all‐polymer solar cells (all‐PSCs). However, medium‐bandgap PSMAs are often overlooked, while they the third component can be expected boost power conversion efficiencies (PCEs) of all‐PSCs, mainly due their up‐shifted lowest unoccupied molecular orbital (LUMO) energy level, complimentary absorption,...

In ad hoc networks, both contention and congestion can severely affect the performance of TCP. our work, we first show that over-injection conventional TCP window mechanism results in severe contentions, medium contentions cause network congestion. Furthermore, introducing two metrics, channel utilization (CU) ratio (CR), characterize status. Then, based on these propose a new transmission rate control Channel Contention (TCPCC). this mechanism, each node collects information about busy...
