We derive closed-form expressions for reasonably tight lower bounds and upper bounds for the signal-to-interference ratio (SIR), and consequently, the coverage probabilities, in wireless cellular networks with heterogeneous spatial traffic distribution, especially in the cases where the locations of the users and base stations are correlated. The traffic model used in this letter is tractable, adjustable,...
Hidden terminals are typical interference sources that can significantly reduce the throughput of a wireless network if it adopts the CSMA/CA MAC protocol. The RTS/CTS mechanism is a well-known solution to this hidden terminal problem. However, it only works well under the assumption that all hidden terminals can decode the CTS packets correctly. In the real world, the CTS packets might not be correctly...
This paper represents the design of Interference Resistant Multiple Access (IRMA), a novel cross layer protocol that can combat exposed terminals and exploit the concurrent transmissions in wireless networks, both helping in achieving higher throughput compared to the 802.11 standard and other recent protocols. By observing that nodes in current protocols waste transmission opportunities in two different...
