Optimal Discrete Power Control in Poisson-Clustered Ad Hoc Networks

Abstract: Power control in a digital handset is practically implemented in a discrete fashion and usually such a discrete power control (DPC) scheme is suboptimal. In this paper, we first show that in a Poison-distributed ad hoc network, if DPC is properly designed with a certain condition satisfied, it can strictly work better than constant power control (i.e. no power control) in terms of average signal-to-interference ratio, outage probability and spatial reuse. This motivates us to propose an N -layer DPC scheme in … Show more

“…whereH ab is the mean of channel gain H ab , k is a constant determined by the communication environment, d ab is the distance between the node a and b, and c is the path loss exponent and usually c > 2 [24]. Compared with the large-scale fading of the relay location, we are going to ignore the Rayleigh fading in the analysis which simplifies the mathematical analysis [23], thus Q can be expressed in terms of the inter-node distance and the channel gain is proportional to (d ab ) −c .…”

“…The authors of [21] designed a power control MAC by considering an optimal hop distance in a dense single cell network, but the approached considers an existence of no hidden nodes. In order to improve the average signal-to-interference ratio, outage probability, and spatial reuse, the authors of [22] studied if discrete power control is better than no power control when the nodes of the Ad Hoc networks are in the form of a Poison-distribution.…”

“…The protocol also creates application of a kernel-based link quality estimator which agrees to pick the most appropriate gateways with load balancing and disconnection predication capability in each cluster. In [19], N-layer discrete power control scheme is design to improve larger transmission capacity and spatial reuse factor in a cluster with Nlayers. In [20], problem related to non-uniform load distribution in mobile ad hoc network is studded and proposed light-weighted dynamic channel allocation and cooperative load balancing algorithm based on cluster.…”
