On the Capacity of K-MPR Wireless Networks

Free registration required

Executive Summary

The capacity of wireless ad hoc networks is mainly restricted by the number of concurrent transmissions. Recent studies found that Multi-Packet Reception (MPR) can increase the number of concurrent transmissions and improve network capacity. This paper studies the capacity of 2-D wireless networks wherein each node can decode at most k simultaneous transmissions within its receiving range. The authors call such networks k-MPR wireless networks. For comparison, they call traditional networks 1-MPR wireless networks. Suppose that the number of nodes in a wireless network is n and each node can transmit at W bits/sec.
