Abstract Opportunistic communication between two encountered nodes is commonly established using a radio technology, such as Wi-Fi or Bluetooth. One issue involved in opportunistic communication is a trade-off between connection time and probability of resource consumption. This paper presents a comprehensive study on density analysis for decentralized distributed opportunistic communication using Wi-Fi technology. In this work, study and analysis of contact probability and energy efficiency of variant density in a particular area are performed. The contribution of this work is the analysis of the impact of density on the connection probability and resources, as well as a simulation study framework to analyze the contact event with a view of energy consumption. The study gave detailed contact information, such as contact probability based on node density and transmission range in a particular area, as well as the beacon exchange process as an element of channel utilization and energy consumption. The influence evaluation of various parameters on each other and finally on the system performance is also presented.
