Fast Modular Multiplication using Parallel Prefix Adder

Public key cryptography applications involve use of large integer arithmetic operations which are compute intensive in term of power, delay and area. Modular multiplication, which is frequently, used most resource hungry block. Generally, last stage of modular multiplication is implemented by using carry propagate adder whose long carry chain takes more time.

In this paper, modulo multiplication architectures using Carry Save and Kogge-Stone parallel prefix adder are presented to reduce this problem. Proposed implementations are faster as compared to conventional carry save adder and carry propagate adder implementations.

MAC: Protocols for Cognitive Radio Sensor Networks and their Comparision

Wireless Sensor Networks (WSNs) deliver smart communication paradigm which can set up intelligent networks handling all the applications as per the user requirements. The WSNs offer several advantages like flexibility, fault tolerance, low cost and easy deployment. Typically, a WSN consists of spatially distributed autonomous sensors to monitor physical or environmental conditions. 

These sensors generate report over the network on the occurrence of any event. For a WSN to provide better reliability and improved lifetime, an efficient Medium Access Control (MAC) protocol design holds a paramount importance. Several multichannel MAC protocols exist which performs better than the single channel protocols. 

The MAC layer coordinates transmission between the users sharing a spectrum and improves the throughput and energy efficiency. Cognitive Radio (CR) is an adaptive, intelligent radio and network technology that can automatically detect available channels in a wireless spectrum and make those channels available for concurrent transmissions.

Dynamic spectrum access in the form of cognitive radio provides spectrum efficient communication for all WSNs which led to the development of Cognitive Radio Sensor Networks (CRSNs). This paper highlights an intensive survey of MAC protocols defined for WSNs and the design of Cognitive Radio based WSNs.

Effect of Lime on Engineering Properties of Cohesive Soil

Soil is a unique natural material and the properties of soils can be altered by adding stabilizing agents such as lime. Lime is the oldest traditional stabilizer used for soil stabilization. Lime is one of the several products that can be used in the improvement of the engineering characteristics of soils. This research presents the effect of lime on engineering properties of cohesive soil. In order to identify and classify this soil, at first physical properties of soil are determined.

 And then, mechanical property tests are conducted. Next, lime is added to natural soils. Lime contents are selected as 4%, 6% and 8% by weight of natural soils. The plasticity index decrease with increasing the percentage of lime content. Soil is mixed with selected lime contents at their maximum dry density. In cohesive soil, the more the lime content, the more the cohesion. The lowest value of cohesion is 0.59 kgcm2 at lime 4% and it increases according to lime content. The percentage of lime increased, CBR value is also increased.

Review on Congestion Control Algorithm for VANET

Vehicular ad hoc networks (VANETs), which is a subclass of Mobile ad hoc networks, have recently been developed as a standard means of communication among moving vehicles because it has tremendous potential to improve vehicle and road safety, traffic efficiency. VANET applications have the characteristics such as fast change of topology, bandwidth limitation and lack of central coordination that causes network congestion which restricts the network performance. 

Number of solutions proposed to overcome these challenges and to reduce congestion on VANET. These solutions include congestion control algorithms, some of them based on maintaining the beacon load below certain threshold value by adjusting transmit power or transmit rate or both. And others are based on utility function, carrier sense threshold, prioritization or a combination of them.

Hence, this study takes a closer look at existing congestion control algorithms to solve congestion problems because it affects the performance of safety messages. The study further exposes the weaknesses and advantages of some of these congestion control algorithms, which can be helpful to tackle with the problems of congestions in VANETs.

A Research Paper on Design and Analysis of Shaftless Steam Turbine

Shaftless Steam Turbine consists of a Double row spherical roller bearing, the outer race of which is provided with a tight fit ring. The periphery of the ring forms base for mounting rotor blades. The inner race is fixed by a suitable arrangement. A hollow frustum tapered cone whose larger diameter is fastened to outer race ring and smaller consists of a flange which couples with generator shaft. The cone transmits the rotational motion of the rotor. A nozzle provides sufficient enthalpy drop to the turbine.

Dynamic Channel Allocation for Wireless Zone Based Multicast and Broadcast Service

In wireless Multicast Broadcast Service (MBS), the common channel is used to multicast the MBS content to the Mobile Stations (MSs) on the MBS calls within the coverage area of a Base Station (BS), which causes interference to the dedicated channels serving the traditional calls, and degrades the system capacity. The MBS zone technology is proposed in Mobile Communications Network (MCN) standards to improve system capacity and reduce the handoff delay for the wireless MBS calls. 

In the MBS zone technology, a group of BSs form an MBS zone, where the macro diversity is applied in the MS, the BSs synchronize to transmit the MBS content on the same common channel, interference caused by the common channel is reduced, and the MBS MSs need not perform handoff while moving between the BSs in the same MBS zone. 

However, when there is no MBS MS in a BS with the MBS zone technology, the transmission on the common channel wastes the bandwidth of the BS. It is an important issue to determine the condition for the MBS Controller (MBSC) to enable the MBS zone technology by considering the QoS for traditional calls and MBS calls. In this paper, we propose two Dynamic Channel Allocation schemes: DCA and EDCA by considering the condition for enabling the MBS zone technology. Analysis and simulation experiments are conducted to investigate the performance of DCA and EDCA.
