# Wireless Node Cooperation with Resource Availability Constraints

## TL;DR

This paper proposes a new station grouping method for cellular networks that considers both geographic proximity and resource availability, deriving analytical formulas to evaluate cooperation benefits under resource constraints.

## Contribution

It introduces a resource-aware grouping criterion and provides analytical formulas for cooperation metrics in Poisson network models, extending prior proximity-based approaches.

## Key findings

- Cooperation gains depend heavily on resource distribution.
- Analytical formulas quantify cooperative pair proportions.
- Resource-aware grouping improves network performance insights.

## Abstract

Base station cooperation is a promising scheme to improve network performance for next generation cellular networks. Up to this point research has focused on station grouping criteria based solely on geographic proximity. However, for the cooperation to be meaningful, each station participating in a group should have sufficient available resources to share with others. In this work we consider an alternative grouping criterion based on a distance that considers both geographic proximity and available resources of the stations. When the network is modelled by a Poisson Point Process, we derive analytical formulas on the proportion of cooperative pairs or single stations, and the expected sum interference from each of the groups. The results illustrate that cooperation gains strongly depend on the distribution of available resources over the network.
