Based on a stochastic geometry framework, the authors establish an analysis of the Multi-hop Spatial Reuse Aloha protocol (MSR-Aloha) in ad hoc networks. They compare MSR-Aloha to a simple routing strategy, where a node selects the next relay of the treated packet as to be its Nearest receiver with a Forward Progress toward the final destination (NFP). In addition, performance gains achieved by employing adaptive antenna array systems are quantified in this paper. They derive a tight upper bound on the spatial density of progress of MSR-Aloha.
