A Quality of Experience (QoE) parameter of increasing importance is the time that a battery powered communication device (e.g. smartphone) can be operated before it needs to be recharged. However, due to the fact that battery capacity is not evolving as fast as the power requirement, the battery lifetime of modern user equipment is stagnating or even decreasing from one device generation to another. In parallel, a major challenge for the design of next generation wireless systems such as LTE-Advanced (LTE-A) is that the required high portion of spectrum is not available in a consecutive portion. For this reason, a procedure called interband non-continuous Carrier Aggregation (CA) will be introduced in LTE-A which allows for the combination of multiple spectrum pieces from different frequency bands. This procedure however requires the parallel operation of multiple power amplifiers that are characterized by a high energy demand. In this paper, we quantify the impact of CA on the power consumption of LTE-A enabled communication by means of a Markovian based power consumption model that incorporates system parameters as well as context parameters. The results show that the suitability of CA does from a battery lifetime perspective strongly depend upon the actual device characteristics as well as the resource availability is the various frequency bands. Furthermore, the application of the sophisticated Kinetic Battery Model (KiBaM) shows that the charge recovery effect during idle periods does significantly affect the battery lifetime.

Designing millimeter wave (mmWave) cellular system with good coverage necessitates the use of directional beams to transmit synchronization signals in the system, and with that comes several challenges. In this paper, we present a detailed synchronization channel (SCH) design for mmWave systems. We provide a link-budget study to determine the minimum required transmit and receive beamforming gains. We also present designs for the SCH pattern in the frame structure. We design SCH sequences and show that our design provides a 3 dB better performance than LTE under similar conditions. Moreover, we propose a method is based on a genetic algorithm, to efficiently synthesize the beams required to transmit SCH.

Conventional cellular mobile networks are likely to get disturbed easily when a natural disaster (earthquake, tsunami, flooding, etc.) hits an area because of their centralized control and high-power requirements. To address this issue, we propose a new mobile network architecture having distributed controls and ad-hoc configurations. This architecture exploits the locally available resources such as frequency spectrum and lively nodes to reconfigure the network and provide emergency services. We present its design and use cases.

Most of the researches pay attention to minimize the end-to-end delay rather than reduce the usage of radio. However, some information is not urgent and radio is a valuable and limited resource. Recently, delay-bounded routing protocol has become a popular issue, whose goal is to deliver messages to the destination within user-defined delay and minimize the usage of radio. To decrease the burden on the environment and save energy, the hybrid-solar vehicle is one of the most prominent solutions. The existing delay-bounded routing protocols do not consider the charge and the energy expenditure factors and only choose the path with the least forwarding times. To improve previous works, we propose a mechanism based on a cost function, which includes forwarding times and power gain, to choose a minimum cost path. Besides, we propose a novel mechanism to deliver message to the destination by the hybrid of data muling (carried by the vehicle) and forwarding (transmitted through radio). In the existing protocol, when the remaining time is not enough the vehicle should forward the message by radio and when the remaining time is enough the vehicle should carry the message by itself. However, forwarding message by radio consumes more energy and hence the energy factor should be added into the consideration. The proposed protocol contains two schemes: the greedy and centralized schemes. In the centralized scheme, the information such as the solar illumination, length of each road segment, and the average velocity of the vehicles on each road segment are collected and then the dynamic programming is used to find the least cost routing path. In the greedy scheme, it only has the knowledge of the average velocity, the solar illumination and the length of all the possible next road segments to choose the next road segment with the least cost. Simulation results illustrate that the proposed routing protocol can save more energy than existing protocols.

Real-time video applications, such as video conferencing and video surveillance systems, typically involve the simultaneous transport of multiple video sources to interested parties that consume the content. It may be desirable to mix these multiple source videos into a single video stream at intermediary nodes in the network. This has the advantage of reduced application and transport complexity on the client device and also makes it possible for devices with a single hardware decoder to consume the content. A typical approach is to apply transcoding operations to the original videos, i.e. the videos are decoded, merged and encoded into a single video stream. This paper proposes an alternative solution to video transcoding, which uses the new video coding standard HEVC and has a much lower processing complexity. We consider how our approach can be realized in real-world applications such as a cloud video mixer. Such systems typically require some degree of dynamics and personalization and we provide some insight into how transport signaling complexities can be addressed.

Next generation wireless backhaul systems may provide data rates exceeding 10 Gb/s using large bandwidth available at mmWave frequencies, and support features such as point-to-multipoint communication, non-line-of-sight communication, in-band operation (shared spectrum with access) and inter-BS coordination. We explore the feasibility of an “in-band” mmWave wireless base-station with the option of enabling backhaul transmission on one panel while simultaneously receiving access or backhaul on an adjacent panel. We show using simulations and lab measurement validation, that for a prototype 28 GHz mmWave system, the self-interference from the TX sector panel to the adjacent RX panel is around -70 to -80 dB and an additional 35-50 dB isolation is needed for enabling reception on adjacent RX panel that may be achieved through full duplex interference cancellation techniques.

As mobile devices become prevalent in workplaces, it also creates a unique environment, Bring Your Own Device, in enterprise networks. BYODs are extensions of corporate networks and thus it is essential to secure BYODs to protect enterprise networks. Security tools such as firewalls, anti-virus software, and anti-spam software have been widely used to protect corporate networks. Similar tools are also desired to protect BYODs. BYODs have many advantages, such as reducing companies' cost and increasing users' productivity. However, they also raise many security issues and challenges due to their unique security requirements. This paper summarizes threats and attacks on BYODs and reveals their security issues and challenges. The paper further compares existing BYOD solutions and presents a BYOD security framework that provides guidance for enterprises when adopting BYODs.

Recently, due to a explosive growth in the mobile Internet traffic, the problem of excessive data traffic handling on core network and thus scalability problem have been magnified in 3GPP Long Term Evolution/System Architecture Evolution (LTE/SAE) networks. Current LTE/SAE network based on the central packet data network gateway (P-GW) used as mobility anchor cannot deal with such problems. In this paper, we propose a new LTE/SAE network architecture supporting distributed P-GWs and the corresponding distributed mobility management to solve the problems. For this, in addition to the deployment of such distributed P-GWs, we propose a dynamic and distributed mobility management by distributing MMEs (Mobility Management Entities) which dynamically manages the location information of an UEs PDN connection, and also propose a handover procedure of such PDN connections by using the proposed distributed P-GWs and MMEs. The performance of the proposed distributed LTE/SAE network system is compared with the conventional LTE/SAE network system in terms of the P-GW's data processing volume per unit time and the number of valid data sessions accommodated in the LTE/EPC core network.

Evolved Multimedia Broadcast Multicast Service (eMBMS) has recently attracted a great attention from the telecommunication industry. All big companies in the field have invested and intended to deploy eMBMS as the broadcast solution in response to the immense demand in multimedia traffic. The eMBMS, also known as LTE broadcast, can provide high quality live video streaming services for a large number of users simultaneously in an open area such as a stadium or arena during an entertainment or sport event. Nowadays, in a high mobility environment, maintaining the service reception for moving users becomes a crucial task for mobile operators and service providers. Unfortunately, the support from LTE standard for eMBMS service continuity is very limited at the moment and in many cases, the users cannot continue to receive their desired services. To overcome the limitation in the standard, this paper will present a novel method to ensure the service continuity as well as to reduce the service interruption time during handover period for eMBMS users in the mobility context.
