NODE DENSITY IMPACT ON ENERGY AND CONTACT OF OPPORTUNISTIC NETWORK

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