Handover in LTE is purely hard handover. The use of break-before-connect handovers reduces the complexity of the LTE network architecture. However, the hard handover may result in data being lost. A Handover algorithm is needed for making handover decision. This decision may vary over time, depending on user's mobility. Many handover algorithms have been proposed. In this work, we optimized three...
The security problems of the tactical mobile ad hoc networks have become a research hotspot in recent years. For its characteristics of multi-hop, energy limited, strong self-organization, high mobility and so on, a cluster mobility model meeting the battlefield practical application is proposed. In this model, the DDoS attacks are introduced to the tactical mobile ad hoc networks in both standby...
A characteristic feature of ad hoc networks is the infrastructure less and seamless connectivity of the wireless mobile nodes. Mobility plays an important role in the connectivity of these nodes. In this paper a performance comparison of five important mobility models; community model, Group Force Mobility Model (GFMM), Reference Point Group Mobility (RPGM), Manhattan Mobility Model and Random Waypoint-Steady...
