Estimating Buffer Occupancy sans Message Exchange in Mobile Opportunistic Networks
Gourish Goudar, Suvadip Batabyal · IEEE Networking Letters · 2022
The multi-copy routing schemes in a mobile opportunistic network (MON) lead to buffer congestion, thereby affecting the network performance. This calls for a proactive buffer management policy for congestion mitigation. Existing works on buffer management in MONs require additional message exchange and are reactive in nature. In this letter, we devise a generalized probabilistic routing model to analyze and estimate the average buffer occupancy, without message exchange. We then estimate the buffer overflow probability using the Chernoff’s bound. The accuracy of the theoretical model is validated through simulation using a synthetic mobility model and a real-life mobility trace.
