System Architecture Evolution (SAE) with Long Term Evolution (LTE) has been used as the key technology for the next generation mobile networks. To support mobility in the LTE/SAE-based mobile networks, the Proxy Mobile IPv6 (PMIP), in which the Mobile Access Gateway (MAG) of the PMIP is deployed at the Serving Gateway (S-GW) of LTE/SAE and the Local Mobility Anchor (LMA) of PMIP is employed at ...

The rapid growth in mobile traffic leads to the current evolution trend of mobile networks towards a flat architecture. However, the centralized mobility management protocols (e.g. MIPv6, PMIPv6) are not optimized for the flat architecture due to their limitations e.g. complex tunnel management, scalability issue, etc. Hence, a novel mobility management has been proposed for the flat architectu...

The AutoWitness project aims to deter, detect, and track theft of everyday objects using a combination of ultra lowpower mobile tags and a wide-area network of static anchors. Key research challenges include dramatically driving down the cost and size of tags and increasing their lifetime, discriminating between normal activities and theft using motion detection and classification algorithms, r...

For the inter-LMA network environment in PMIPv6, location information of communicating Mobile Node(MN) and Correspondent Node(CN) is maintained in the different Local Mobility Anchor(LMA). Accordingly, when both MN and CN move to different MAGs simultaneously, race condition occurs in which updated location information of MN is forwarded to the previous MAG of CN. In this paper, an inter-LMA Ro...

Recently, as the development cycle of applications has been shortened, it is important to develop rapid and accurate application testing technology. Since requires a lot cost, mobile component detection technology using deep learning essential prevent use expensive human resources. In this paper, we shall propose Clickable Object Detection Network (CODNet) for in wide range screen resolutions. ...

In IP-based mobile networks, a few of mobility agents (e.g., home agent, foreign agent, etc.) are used for mobility management. Recently, Hierarchical Mobile IPv6 (HMIPv6) was proposed to reduce signaling overhead and handoff latency occurred in Mobile IPv6. In HMIPv6, a new mobility agent, called mobility anchor point (MAP), is deployed in order to handle binding update procedures locally. How...

Abstract — In IP-based mobile networks, a few of mobility agents (e.g., home agent and foreign agent) are used to support seamless mobility. In terms of network performance, scalability at these agents is one of the most important issues in mobile networks. In Hierarchical Mobile IPv6 (HMIPv6), a new mobility agent, called mobility anchor point (MAP), is deployed in order to handle binding upda...

Sensor nodes transmit the sensed information to the sink through wireless sensor networks (WSNs). They have limited power, computational capacities and memory. Portable wireless devices are increasing in popularity. Mechanisms that allow information to be efficiently obtained through mobile WSNs are of significant interest. However, a mobile sink introduces many challenges to data dissemination...
