We study a multi-source wireless power transfer (WPT) enabled networksupporting multi-sensor transmissions. Activated by energy harvesting (EH) frommultiple WPT sources, sensors transmit short packets to a destination withfinite blocklength (FBL) codes. This work for the first time characterizes theFBL reliability for such multi-source WPT enabled network and providesreliability-oriented resource allocation designs, while a practical nonlinearEH model is considered. For scenario with a fixed frame structure, we maximizethe FBL reliability via optimally allocating the transmit power amongmulti-source. In particular, we first investigate the relationship between theFBL reliability and multiple WPT source power, based on which a powerallocation problem is formulated. To solve the formulated non-convex problem,we introduce auxiliary variables and apply successive convex approximation(SCA) technique to the non-convex component. Consequently, a sub-optimalsolution can be obtained. Moreover, we extend our design into a dynamic framestructure scenario, i.e., the blocklength allocated for WPT phase andshort-packet transmission phase are adjustable, which introduces moreflexibility and new challenges to the system design. We provide a joint powerand blocklength allocation design to minimize the system overall errorprobability under the total power and blocklength constraints. To address thehigh-dimensional optimization problem, auxiliary variables introduction,multiple variable substitutions and SCA technique utilization are exploited toreformulate and efficiently solve the problem. Finally, through numericalresults, we validate our analytical model and evaluate the system performance,where a set of guidelines for practical system design are concluded.
