Nowadays Mobile phones are becoming more popular in our daily lives. Mobile technology has a great effect on human life. Our daily tasks are dependent on mobile devices. Memory Management (MM), Security and Performance plays an important role in every handheld device specially in mobile phones, which are very much dependent on their operating system (OS). These embedded operating systems are on the driving seat when we talk about efficient and useful memory management and secure handling. Three popular OS in mobile phones are Android, Windows and iOS (iPhone OS). Each OS has its own way of managing the memory and provide it to certain number of applications. Android is an open software available for the people to modify as per their needs. But Windows and iOS operating systems didn"t allow their software as open source. Researchers have done a large amount of work using different mechanisms and decision makings to develop new ways to manage the memory of these OS"s. This work shows a comparative analysis of different memory management and security related techniques in above three operating systems. In this paper, we present the analysis of memory management and security in mobile phone operating systems with respect to apps, main memory, cache memory and virtual memory. Also, we compare the overall performance of these OS"s in terms of MM, security concerns. This study will help in finding better operating system in terms of efficient memory management and security.

“…Thus a higher performance is the major focus. A high performance is the most important feature of gaming notebooks, but in order to extend the battery life while in the battery mode, the designer will directly reduce the performance in order to reduce power consumption, so as to maintain a high-performance state, which can be a dilemma in the battery mode [2]- [5]. Other major laptop designers emphasize the performance that is not focused on the battery mode.…”

This new design uses a low power embedded controller (EC) in cooperation with the BIOS of a notebook (NB) computer, both to accomplish dynamic adjustment and to maintain a required performance level of the battery mode of the notebook. In order to extend the operation time at the battery mode, in general, the notebook computer will directly reduce the clock rate and then reduce the performance. This design can obtain the necessary balance of the performance and the power consumption by using both the EC and the BIOS cooperatively to implement the dynamic control of both the CPU and the GPU frequency to maintain the system performance at a sufficient level for a high speed and high resolution video game. In contrast, in order to maintain a certain notebook performance, in terms of battery life it will be necessary to make some trade-offs.

“…With the fast development of wireless technologies [2,3] and wide deployment of 3G/4G/LTE base stations and WiFi hotspots [4,5], the mobile devices can be connected to the Internet at anytime and at anywhere [6], where the communication among peers becomes more convenient. On the other hand, the storage capacity of mobile devices is increasingly large [7]. For example, Apple and Samsung have released phones with the 128GB storage module; Seagate has developed a 5 mm ultrathin hard disk drive (HDD) with 500GB storage capacity for mobile devices [8].…”

The mobile devices have become the norm, rather than an exception for people's daily life, and these devices possess strong ability (e.g., increasingly large storage) to serve as content sources in future information-centric networks, e.g., named data networking (NDN). The efficient discovery of contents provided by mobile devices is a challenging task. Most of existing studies adopted ID-Locator split architecture to handle the problems raised by source mobility in NDN, e.g., the content source is suddenly disconnected from the network when providing on-going services. However, these solutions require very high control overhead to maintain upto-date location information of sources in an ID-Locator mapping system. Software defined networking (SDN) is a promising tool to make cross-layer decisions based on its logically centralized controller, and thus can facilitate the implementation of forwarding strategies in NDN according to application requirements. To this end, this paper proposes a new packet forwarding algorithm under SDN paradigm that is able to update the forwarding information base (FIB) of NDN node considering both the mobility pattern of mobile sources and network states. In particular, the algorithm leverages the SDN controller to perform the tradeoff between global FIB updates on all NDN nodes and local FIB updates on NDN nodes that are previously connected by mobile sources to lower the control overhead. A discrete-event simulator based on NS3 simulation framework is developed to validate the effectiveness and feasibility of the proposed algorithm. In addition, the performance of the algorithm is compared with that of existing solutions based on ID-Locator split architecture. The results show that the proposed packet forwarding algorithm has a lower request-to-response latency and higher successful content request ratio with reduced control overhead under different working conditions.
