Named Data Networking is a new method of sending data request without knowing the details of hosting machines. Also, it uses data name in the place of IP address to avoid IP related issues. The two main benefits of NDN are capability to efficiently manage security and mobility problems.

This article completely deals with Mobility Management in Named Data Networking along with recent research facts!!!

On using in-network caching, NDN enables user-side mobility and hand-off. When the clients change their position, then the demanded data will be cached among routers. In specific, it supports client mobility in the absence of provider mobility. At the moment, internet architecture is under the issues of mobility without knowing the NDN mobility advantages. Therefore, the current researchers are moving in the direction of NDN field. Basically, the NDN based Mobility management supports following requirements.

  • Low UE participation
  • Handover and Handoff abilities
  • Efficient resource utilization

What is NDN architecture?

In fact, NDN is referred as information / content-centric networking (ICN / CCN) which is on the way to create positive impact on next generation internet architecture. Whereas, it is largely inspired by in-depth research and usage of networking for data forwarding in large-networks. Moreover, it also addresses the issues related to IP addresses in present internet architecture. Here, we have given the elements of data packets in two different scenarios of named data networking.

Scenario 1

  • Content Name
  • Signed Information (stale time, publisher ID and key locator, etc.)
  • Signature (key locator, publisher ID, stale time, etc.)
  • Data

Scenario 2

  • Content Name
  • Nonce
  • Selector (publisher filter, scope, order preference, etc.)

Outline of Mobility Management in NDN

As mentioned earlier, NDN utilizes data name as an alternative of IP addresses to enable data access. This is purposely designed to satisfy the need of the mobile users / clients. Since, the mobile users frequently different IP addresses to process their communication. So, if there is a problem in acquiring IP address then it may create incontinent communication. To overcome this problem, mobility management in named data networking is proposed. Here, we have given some fundamental difference among NDN mobility and IP-mobility problem.

  • Elimination of Link-oriented sessions
    • In the case of internet, it is required to re-establish TCP connection while high node mobility. Also, it needs to manage sessions to continue the communication
    • In the case of NDN, it need not to manage session and re-establish TCP connection
  • Multi-Homing of Host
    • In the case of internet, each application uses separate link to connect with multiple network interfaces. And, every interface uses separate IP address to launch the communication.
    • In the case of NDN-oriented applications, it uses content name to concurrently transmit request to multiple network interfaces
  • Scoping of Where and What
    • In the case of internet, the clients are linked with their location because IP address do not support on other location
    • In the case of NDN, the data can be accesses from anywhere at any time because the clients are not linked with their location
  • Reliability of Network Address
    • On using IP addressing, routing protocols are required to handle routing table in the network.
    • It may cause more overheads in huge-scale network like constrained scalability, slow convergence, etc. 
  • Flexibility via Replication
    • In the case of IP addressing, when the host is not properly detected in routing then the data may lose
    • In the case of NDN, the mid-way router caches the demanded for continuous communication without data loss

Next, we can see about the different types of mobility in named data networking models. Here, our research team has given you elaborated information on these varieties. Since, we have largely handled these two types in many mobility management related applications in NDN. So, we are adept to solve any kind of complicated challenges in these mobility types.

Types of Mobility in NDN

  • Provider Mobility
    • Although the effect of provider mobility is reduced by popular contents repetition and caching methods, the unpopular contents are still getting suffered. So, the requirement of the effective provider mobility solution is increases and turn into big research challenge.
  • Consumer Mobility
    • Generally, consumer mobility is inherent feature in the NDN whereas provider mobility influences the scalability and overhead related problems. If the provider constantly changes their position, then it is required to update the locator details.

As a matter of fact, NDN mobility reduces the hand-off latency due to the accessibility of repeated content and cached through node between provider and consumer. Though it reduces the latency, it has issue of less usage of caching in real-world scenarios. So, the real-time content (multimedia) has become another big research challenge in NDN.  

Most probably, crowd-sourcing is used to enable vehicles for gaining information. In this, information authentication without provider’s ID revelation is the major issue to authenticate data without revealing provider’s identity.

Then in order to solve the content provider mobility, mapping-based technique is used. This technique is intended to give current location of moving content providers against the query of particular user. Further, we also highlighted the core aspects of NDN mobility in the followings,

NDN Mobility

  • Hand-off Management
  • Provider’s Mobility
    • Locator-free and Mapping-based

So far, we have completely discussed about the NDN, mobility management and mobility management in NDN. Now, we can see the significant research issues of NDN-based mobility management. Our research team has framed several best-fitting solutions not only for these issues but also for other major issues. Once you communicate with us, we are ready to share our appropriate solutions.

Ongoing issues in NDN mobility management

In addition, we have also given other major issues that are essential to take extra attention on modelling mobility management in NDN. Since, these issues may influence the performance of mobility management.

Specific issues to be taken into consideration includes:

  • Boost the traffic control in the time of handover delay and losses. Since, long sessions are inclined to failures because of high host moves and short session are inclined to end prior to migration / handover
  • Enhance reliability of data and control planes in terms of location, mobility detection, route length, overhead, etc.
  • Increases the collaboration of remote peers
  • Improve scalability to single administrative fields, end-to-end model, local websites, device / network centric models, etc.
  • Consider mobility elements such as session migration, handover, entities detection, service probability, etc.

Furthermore, we have included few key factors used to improve the mobility management. These factors play a major role in enhancing the efficiency and quickness of the handover establishment. We are sure to consider to the following factors in developing effective mobility management models for NDN.

How to solve mobility issue in NDN?

Although NDN comparatively has more advantages over IP addressing, it has some methodical issues. The most important issue is offering mobility support for both content requesting client and content delivering provider. Similarly, mobility management in named data networking incorporates other following challenges.

  • Offer advance mobility management (user-centric environs)
  • Provide user-centric environ and handover optimization
  • Give nomadic end-user involvement and session continuity
  • Reconstruct mobility on considering static mobility / centralized anchoring

In fact, handover is the most important research solution for many issues of mobility management in NDN. For more clarity, we have given the list of possibilities to address the mobility management issues through handover process. Let’s have a quick look over them,

  • Mobility Anchor Points Selection
    • Faultlessly
    • Reliable links
    • Anyplace at anytime
    • Expectancy of clients
    • Environs (resources, mobility behaviour and social patterns)
    • Features (services, technology and applications)
  • Verify QoE parameters and cost functions

In the case of consumer mobility, it checks whether the handover is forecasted to due soon and required to pre-fetch, the consumer inform their connected router to choose subgroup of neighbor router. As a result, it proactively pre-fetch the requested contents. When the handover begins, then the consumer stops demanding content and router stops distributing packets. Specifically, it happens when there is no interest for content, exceeded cache size and completed handover. All these elements make pre-fetching to stop. Then, the consumer demands content from new router. Once the router is connected then the consumer prefers to receive content fast before new router produce multicast interests.
