This paper presents efficient motion detection of mobile node (MN) based on weighted momentum of received signal strength (WMRSS) in support of better handoff management in wireless network. In this method, for making momentum of received signal strength (MRSS) more accurate in detecting motion of MN, weight is applied to the received signal strength (RSS) of MN according to the priority and weighted average determined in calculating exponential moving average (EMA). To make WMRSS more effective and sensitive to the motion of user, dynamic smooth factor is used hence the method is called dynamic WMRSS (DWMRSS). Numerical simulation results are presented for DWMRSS method and compared with DMRSS scheme. Obtained result shows that the proposed method detects the motion of MNs more effectively and helps to reduce unnecessary handoff and loss of power.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
