Cooperative Mobility Control Strategy for Improving Communication Quality in Combination of Intra and Inter Networking in Multiple WBANs

In this paper, we consider a quality control of body-to-body networks (BBN) communication, which is communication between WBANs, in a situation where multiple WBANs coexist and have mutual interference. In multiple WBANs using the same channel, interference between WBANs and throughput of BBN communication depend on the distance between WBANs. Based on the communication characteristic, we propose a strategy where we move people with WBANs. Unlike conventional methods, the proposed strategy maximizes the throughput of BBN and mitigates interference between WBANs with no additional costs such as modification of protocols or hard/software. Our evaluation result showed that the proposed strategy provides the optimal location which can improve throughput of BBN by 58% than the initial location while satisfying the minimum performance of Intra-WBAN required by the user.
