ABSTRACT
The purpose of this paper is to present a new method for the study of competition and cooperation relationships among nodes in a network with a CSMA (Carrier Sense Multiple Access) protocol implemented with an exponential backoff process. Self-organized behavior is proposed. We propose a "Channel Utilization Model" with a new derived variable "channel access rate" which applies for all traffic loads. These models are applied with different optimization methods.

Starvation mitigation through multi-channel coordination in CSMA multi-hop wireless networks
MobiHoc '06: Proceedings of the 7th ACM international symposium on Mobile ad hoc networking and computingExisting multi-channel protocols have been demonstrated to significantly increase aggregate throughput compared to single-channel protocols. However, we show that despite such improvements in aggregate throughput, existing protocols can lead to flow ...
Contention in multi-hop wireless networks: model and fairness analysis
MSWiM '09: Proceedings of the 12th ACM international conference on Modeling, analysis and simulation of wireless and mobile systemsIn multi-hop wireless networks with Carrier Sense Multiple Access (CSMA), unfairness may arise due to a number of reasons. A majority of the existing work focuses on fairness issues due to hidden terminals and the impact on backoff mechanisms. This ...
