Performance analysis of the effects of network density and network mobility on velocity-based scheme in Mobile Ad hoc Network

摘要

Broadcasting is essential in Mobile Ad hoc Networks (MANETs). It is used in the initial phase of route discovery process in many reactive protocols that find the route only on demand. Although broadcasting is simple, it causes a broadcast storm problem, which is a result of packets redundancy, contention and collision. A mobility scheme based on velocity of node called (VON) has been proposed to overcome this problem. However, VON uses a fixed threshold regardless of network status. This study aims to study the effects of network density and network mobility on VON scheme. The results could be useful for better prediction of velocity threshold values.
