TLDR
The feasibility of creating opportunistic networks on top of WiFi Direct framework is investigated by analyzing the protocol's performances in real scenarios with a variable number of mobile devices and the times required to form a group of variable size and the best configurations to support opportunistic networking operations and upper layer applications.Abstract:
WiFi Direct introduces new opportunities to deploy real opportunistic networks through users' mobile devices. However, its original specification does not take into account all the parameters that can emerge from an opportunistic network scenario, not only in terms of technical requirements (e.g., available resources and connectivities) but also of users characteristics and profiles, which can heavily influence the system's performances and devices' interactions. In this work we investigate the feasibility of creating opportunistic networks on top of WiFi Direct framework by analyzing the protocol's performances in real scenarios with a variable number of mobile devices. Experimental results show the times required to form a group of variable size and the best configurations to support opportunistic networking operations and upper layer applications.read more
