Context 1... illustrated in Fig. 1, we consider a collaborative sensing network with an edge computing server and N mobile devices (MDs). The operator-deployed MEC server is collocated with the access point at the network edge, and the set of MDs/IoT devices is denoted as N = {1, . . . , N }. Due to the limited battery capacity, MDs may not have sufficient energy to ... Context 2... the network setup above, we propose a new harvesting-sensing-training-transmit protocol.

Context 1... process, and RF energy harvesting is a promising solution. During the first phase of the harvestingsensing-training-transmit protocol, MDs harvest energy from RF signals emitted by the access point. Specifically, the access point simultaneously transfers RF energy to MDs by employing the energy beamforming technique to create N radio beams (see Fig. 2). Denote by P n the transmit power of the beam pointing at MD n, and by P 0 the fixed power budget of the access point.

For the data sensing model, the sensing rate r n is picked at random from the range [1, 5] × 10 6 bit/s, the energy consumption per bit q s n is uniformly distributed in the range [1,10] × 10 −12 J/bit [24], and the required sensing data size is D 0 = 100 Kb.

Context 1... show the performance of the proposed algorithm with different power budgets of the energy source. It is shown in Fig. 5 that the total completion time gets smaller when the power budget P 0 of the energy source becomes larger. It is because increasing P 0 helps MDs to harvest more energy for learning purposes. Therefore, with larger P 0 , one can reduce the time durations for the learning phases and consequently shorten the total completion time. ... Context 2...
