The low-cost and easy-deployable mobile ad hoc networks (MANETs) have great potential to serve as the underlay network architecture for implementing lots of critical applications. In order to support different demands in such applications, understanding the fundamental performance of the MANETs and exploring their performance enhancement are of great importance. To this end, this paper, for the first time, investigates the performance enhancement of the MANETs by appropriately allocating the network resource. Specifically, we consider both the transmission resource and storage resource of a network node and use a two-tuple to depict a general resource allocation configuration. First, for a MANET with any given resource allocation configuration, we establish an analytical framework to model the network dynamics as queuing processes. With the help of the network modeling, we then derive the expressions …
