Abstract

In this paper, we consider two fundamental problems in Log-normal fading networks. One is the energy efficiency. The other is the characterization of the internode interferences and spacial reuse. We first introduce a Power Efficiency Factor as a new parameter to measure the transmit efficiency and obtain an optimal transmit power allocation of the concurrent transmitters in such fading environment. The internode interference caused by the simultaneous transmissions within a local area is then analyzed. The analysis will also be extended to the whole network within unlimited region where the interference accumulative impact is taken into account. By doing so, we set up a direct link between the interference double disc model with the statistical accumulative interference model and derive the optimal spatial reuse distance to guarantee the network efficiency. Finally, we propose a concurrent access strategy, OCMAC (Opportunistic Concurrent MAC), which can efficiently mitigate the internode interference through the node coordination before the simultaneous transmissions while keeping a relatively low transmit power and high spatial reuse efficiency.
