摘要: We develop a new metric for quantifying end-to-end throughput in multihop wireless networks, which we term random access transport capacity, since the interference model presumes uncoordinated transmissions. The quantifies average maximum rate of successful transmissions, multiplied by communication distance, and normalized network area. show that simple upper bound on this quantity is computable closed-form terms key parameters when number retransmissions not restricted hops are assumed to be equally spaced line between source destination. also derive optimum optimal per hop success probability our result follows well-known square root scaling law while providing exact expressions preconstants, contain most design-relevant parameters. Numerical results demonstrate accurate purpose determining count (or outage) probability.
