PCA based components selection criteria for computationally efficient Physical Layer Key Generation (PLKG) system

Data security is one of the prime concerns in wireless networks. PLKG has been emerging as an attractive alternative to traditional cryptographic techniques. PLKG is more computationally efficient than cryptography. Moreover, PLKG using Principal component analysis (PCA) as pre-processing may further save computations. This paper proposes three mechanisms to select components of PCA which are based on Information content, Mean and Histfit. Bit Disagreement Rate (BDR) is compared for each mechanism. Histfit based method is found to be best. Since only two components are supposed to be processed for key generation, it is computationally efficient/ power efficient too

Performance Evaluation of Survivable Fiber-Wireless (FiWi) Access Network

AbstractFiWi support high speed transmission rate, hence any kind of failure may result in huge data loss. To prevent this, there is a requirement to design more survivable and reliable network. In FiWi networks there are two types of failures viz. ONU level failure and segment /OLT level failure. In the present work, to handle segment level failure, we propose an efficient algorithm viz. “Fully Mesh based protection scheme”. In the proposed algorithm we connect backup ONUs from each segment in a fully mesh fashion. Simulation result shows that proposed algorithm improves network survivability in terms of reduced blocking probability

Energy Efficient Rate Adaptation Algorithm for FiWi Access Network

Abstract Similar to any telecommunication network, energy efficiency is a desirable feature for fiber wireless (FiWi) access networks. These networks have optical back end and wireless front end. Both ends may contribute for energy efficiency. This work focuses on front end of FiWi access network, which is IEEE 802.11a wireless local area network (WLAN). For energy saving WLAN uses power saving mode (PSM), in which sleeping opportunity of a station is increased. During sleep time, station remains switched off and results in reduction in energy required. However, it is also observed that during active period of transmission considerable energy is consumed, which is the function of rate of data transmission. More data rate results in more active energy consumption but less transmission delay and vice versa. In order to reduce active and hence total energy consumption, we tried to transmit the data at lower data rate, while maintaining transmission delay in tolerable limit. This paper presents an Energy Efficient Rate Adaptation Algorithm (EERAA) for the front end of fiber wireless access networks. Simulation results compare the energy efficiency and transmission delay of EERAA and various existing fixed data rate schemes. Proposed scheme offers good trade-off between energy efficiency and transmission delay

Fiber wireless (FiWi) access network: ONU placement and reduction in average communication distance using whale optimization algorithm

Explosive growth in the field of Information and Communication Technology demands an access technology which can serve users better Internet speed in ''anytime anywhere” manner. Fiber Wireless (FiWi) access technology is one of the existing technologies that fulfills the current demands of users in cost-efficient manner. Some of the important issues of the FiWi network are ONU placement and energy saving. ONU placement issue affects the deployment cost and network performance while energy saving is the need for green technology. On taking consideration of these two issues we propose a whale optimization algorithm for ONU placement for FiWi network. The proposed algorithm optimizes the position of ONUs in such a manner that all deployed wireless routers can connect to their primary ONUs with minimum possible average communication distance. Simulation is performed for varying number of wireless routers to check the worthiness of the proposed algorithm. Results show that the proposed algorithm reduces the average communication distance between ONU and its associated wireless routers hence, it may offer the best way to deploy energy efficient FiWi network

Computation of Various QoS Parameters for FiWi Access Network

AbstractFiber wireless (FiWi) access network is one of the broad band access networks used to support multimedia applications and interactive services. However minimum QoS needs to be maintained by the network. In this paper a method has been proposed to compute the various network parameters such as packet delivery ratio (PDR), average delay and network throughput for a FiWi network, to ensure minimum QoS. This approach may be proved very useful in computing these parameters comprehensively for any algorithm related with research issues of FiWi network like ONU placement, survivability, energy efficient algorithms etc
