The connectivity capabilities of mobile wireless devices have been forever changing how networks operate, increasingly demanding resources from the network. This places a need for novel mobile network architectures and mechanisms, targeting tomorrows challenges, as envisaged by 5G networks research efforts. This paper sheds a light on an important 5G aspect, namely the interaction of the mobile node...
With the emergence of IOT, WSNs have become prevalent for many application areas such as smart city scenario, healthcare, weather monitoring and intelligent transport system etc. Due to their smaller infrastructure and limited energy resources, these networks are considered to be controlled and lossy networks. IP mobility management in such networks playing a crucial role for object tracking or to...
Now the challenge for the mobile network in reliability is more and more serious. The traditional mobile network management schemes such as Mobile IPv6 (MIPv6) and Proxy Mobile IPv6 (PMIPv6) have hardly taken this issue into account. In this paper, we make an improvement based on PMIPv6 to propose a network based reliable mobility management scheme called R-PMIPv6. The basic idea of R-PMIPv6 is to...
Mobile IP (MIP) was created to enable users keeping the same IP address while traveling to a different network because the mobility function of MIP is performed on the network layer rather than the physical layer so that users can continue their connections without sessions or connections dropped and they remain similar to destination. Mobile IP is scalable for a large number of users and it is most...
Data collection is a basic application of wireless sensor networks, where every sensor node collects data and then forwards data to the Sink node through a multi-hop path. In traditional TDMA scheduling, sensors consume extra energy because of the state transitions which occur numerous times in a TDMA frame. And the longer the length of a TDMA frame, the longer duration of a data collection and the...
Spectrum sensing, as one of the most important aspects, plays a crucial role on mitigating interference of secondary users (SU) in cognitive radio. However, moving primary user (PU) will sharply decrease the stability of observable information by considerably deteriorating the sensing performance. In this paper, a new joint estimating scheme is proposed for tracking PU proactively and detecting the...
To ensure efficient session continuity for every node in a Mobile Network NEMO Basic Support (NBS) protocol, an extension of MIPv6 has been proposed. The protocol NBS is not directly applicable in PMIPv6 domain as it is a network based mobility management protocol and mobility is transparent from mobile node. It is already proved that to support NEMO BSP in PMIPv6 domain some modifications are required...
In the mobile era, the demand for Internet connection for moving vehicles (such as cars, buses and subways) is growing fast. The Network Mobility (NEMO) basic support protocol (B-NEMO) was introduced to provide Internet access for a group of users in a moving vehicle in an effective manner. As an extension of Mobile IPv6 (MIPv6), B-NEMO inherits the limitations from both the host-based and the centralized...
In the era of wireless communication, mobility management is one of the most significant issues to be resolved. Current IP-level mobility protocols such as Mobile IPv6 or Proxy Mobile IPv6 (PMIPv6) have difficulties meeting the stringent handover delay requirements. Besides, when there are many candidate networks, i.e., multiple destination networks, can be selected, a proper selection of Mobile Node's...
Vertical handover management provides seamless connectivity in heterogeneous wireless networks. But still there are different challenges that need to be addressed. These challenges include the inappropriate network selection, wrong cell handover, etc. Therefore, in this article, we proposed a handover management scheme based on the data rate and QoS of available networks. The handover triggering is...
In this paper, we propose a seamless handoff management technique called optimized HMIPv6 (O-HMIPv6), an extension of HMIPv6, which eliminates the DAD procedure and router advertisement latency involved in regular HMIPv6 handoff procedure. The O-HMIPv6 is based on homogeneous prefix concept. The 64 bit IPv6 prefix is divided into two parts: network identifier (NID) and subnet identifier (SID). The...
Estimation of binding lifetime has remarkable impact on the system performance. A longer binding lifetime may provide wrong information about the location of the mobile node where as a very short binding lifetime may cause network overheads in the form of higher exchange of binding refresh messages. The increase in message exchange intensifies the signaling load which in turn generates considerable...
D-PMIPv6 is a Distributed mobility management scheme based on Proxy Mobile IPv6 (PMIPv6) which splits the control and data plane of traditional mobility anchor. Flow mobility support is becoming increasingly common in multi-interfaces environment because it provides flexible network selection per application flow and better network experience for mobile users. Flow mobility support is the missing...
In this paper, we propose a routing protocol for mobile social networks (MSNs) by exploiting the fact that people's daily lives have community preferences. The proposed protocol is capable of efficiently integrating the merits of high delivery ratio, low delivery latency and low resource consumption of the Epidemic, LABEL and BUBBLE protocols for MSNs, while circumventing their respective shortcomings...
In this paper, we propose a Proxy Mobile IPv6 (PMIPv6)-based architecture for Follow Me Cloud (FMC), a concept whereby mobile users are always connected to their optimal Data Centers via their optimal data anchor gateways, enabling not only data but also services to follow users. The approach envisioned in this paper consists of two parts: (i) a PMIPv6-based inter-domain mobility management support...
For mobile multicast, seamless handover and efficient network resource utilization should be achieved together. IP multicast protocol, however, lacks efficient mobility support as it is originally designed for wired networks. Meanwhile, Mobile-IP protocol can provide seamless mobility, but it is designed for unicast communication. Largely, there exist three solutions to glue these two protocols: Bi-directional...
Extending the basic Locator Identifier Separation Protocol (LISP), LISP-MN has been proposed to support mobility. However, LISP-MN only supports host-based mobility, and has some limitations in network mobility scenario. With the number of mobile nodes (MNs) as a group roaming among different network domains becoming larger, the signaling overhead in the system linearly increases. In this paper, we...
Telecommunication means (devices, technologies, etc.) are important components of modern ICT. In their design requirements appear contradictory set of strict accounting quality scores. This determines the need for multi-criteria optimization methods in selecting optimal design solutions from the set of admissible. Problem solving multiobjective optimization is to find, in general, rather than one...
This paper proposes a low-cost global mobility management architecture and protocol procedure called LC-GM2, which is based on Proxy Mobile IPv6 (PMIPv6) networks. The benefit is the elimination of the wireless link data delivery tunnel overhead between a mobile node and the access router. To compare with the well-known Hierarchical Mobile IPv6 (HMIPv6) mobility management protocol and Global Mobility...
the dynamic topology of a mobile ad hoc network poses a real challenge in designing the routing protocol. This paper examine through simulation the fundamental factors, mobility models and transmission power which have a major impacts on the performance of position based routing protocols. We analyse the effect of the transmission power of on the performance of protocols under two different mobility...
