Abstract
Group mobility is prevalent in many mobile ad hoc network (MANET) applications, such as disaster recovery, military operations, searching and rescue activities. Group partition, as an inherent phenomenon in group mobility, may occur when mobile nodes move in diverse mobility patterns and it causes the network to be partitioned into disconnected components. It may result in severe link disconnections, which interrupts network communications. To address this concern, we proposed a novel group mobility model in this paper, namely the Reference Region Group Mobility model, which can be used to mimic group operations in MANETs, i.e. group partitions and mergers. Based on this model, a comprehensive study on the impact of group partitions to the performance of network routing protocols are carried out by evaluating two well-known routing protocols, namely the Ad Hoc On-demand Distance Vector Routing protocol (AODV) and the Dynamic Source Routing protocol (DSR). The simulation results reflect that group partitions have a significant impact to the performance of network routing protocols.

Summary
Mobility models are used in simulation studies to describe the dynamic behaviors of mobile devices in the real world for analyzing and evaluating the performance of ad hoc network protocols under various scenarios [1]. The common characteristic of the above applications is that mobile nodes can be organized in the unit of groups, which could be further partitioned into many subgroups or merged with other groups. Among all the existing group mobility models, none of them can simulate the inherent group operations, i.e., partitions and group mergers which are very common in most practical group mobility related scenarios. Some group mobility models can only be applied to specific scenarios with the restrictions in the aspects of, e.g., fixed group membership, fixed velocity, and predefined paths for group’s movement. By considering these restrictions, most of existing models are unable to describe the behaviors of group mobility realistically
