Mobility Modeling for Personal Networks: Properties and its Impact

User centered personal network (PN) interconnects various devices belonging to a user in different geographic locations, such as home, office, car, etc., to form one network to improve the quality of life of the user. In PNs, the user´s devices move in different groups, where these groups merge and split. A PN mobility model (PNMM) has been proposed to model the devices´ movements in PNs. In this paper, PNMM has been evaluated: stability evaluation proves that PNMM maintains a long-term steady state. The impact of PNMM on the performance of protocols designed for PNs has been discussed in this paper. Simulation results give insights of the performance of the PN clustering protocol, and provide guidelines for future design of clustering in PNs.
