The impact of routing schemes and nodal transmission radius on capacity of IEEE 802.11 DCF Ad Hoc networks is studied with an analytical model in this paper.In a multi-hop network with randomly distributed terminals,and with four routing schemes,try to find the combination to maximize the network capacity.It is shown that,with a given nodal distribution density,the expected progress of packets sent by a node decreases monotonously as the transmission radius increase.This implies shorter transmission radius has an tendency to improve the network capacity.Moreover,with given nodal transmission radii,long-hop routing schemes outperform short-hop routing schemes.
