Abstract-- In this paper we focus on characterizing the average
end-to-end delay and maximum achievable per-node throughput
in random access multihop wireless ad hoc networks with
stationary nodes. We present an analytical model that takes
into account the number of nodes, the random packet arrival
process, the extent of locality of traffic, and the back off and
collision avoidance mechanisms of random access MAC. We
model random access multihop wireless networks as open G/G/1
queuing networks and use the diffusion approximation in order to
evaluate closed form expressions for the average end-to-end delay.
The mean service time of nodes is evaluated and used to obtain
the maximum achievable per-node throughput. The analytical
results obtained here from the queuing network analysis are
