Opis:
Traditional cooperative banks are considered as locally and socially embedded, lending to local clients from locally collected deposits and financing the local economy.. To offset their disadvantage due to their insufficient size, they exploit the information advantage deriving from their geographical proximity to their clients and the advantages of their peculiar corporate governance deriving from the member-ownership. This paper examines the relevant theories on cooperative finance, while examining the underlying geographical and corporate governance aspects in a less advanced transition economy environment. Governments’ preference towards commercial banking and at the same time their negligence towards the cooperatives in general led to a loose financial regulation of the sector. The limits of cooperatives’ corporate governance and demutualization intensify when loosing social/local embeddedness. Cooperative banks, located in the periphery with insufficient socio-economic conditions to develop closer relationships with borrowers accelerate capital flight from their regions. Commercial cooperatives entering new markets show higher lending activity but have more non-performing loans due to the lost information advantage.

Opis:
Faithfull detection of non-utilized spectrum hole in available channel is a crucial issue for cognitive radio network. Choosing the best available channel for a secondary user transmission includes settling on decision of accessible choices of free frequency spectrum based on multiple objectives. Thus channel judgment can be demonstrated as several objective decision making (MODM) problem. An ultimate goal of this exploration is to define and execute a technique for multiple objective optimizations of multiple alternative of channel decision in Adhoc cognitive radio network. After a coarse review of an articles related to the multiple objective decision making within a process of channel selection, Multiple Objective Optimization on the basis of the Ratio Analysis (MOORA) technique is taken into consideration. Some important objectives values of non-utilized spectrum collected by a fusion center are proposed as objectives for consideration in the decision of alternatives. MOORA method is applied to a matrix f replies of each channel alternatives to channel objectives which results in set ratios. Among the set of obtained dimensionless ratios, all the channel alternatives are ranked in descending order. In MOORA, channel choices with moderate objectives can top in ranking order, which is hardly conceivable with linearly weighted objectives of the different channel by using different decision making technique.

Opis:
Mobile Ad-Hoc Network is an wireless systems it supports mobile communication in a network. MANETs are affected by several security attacks but it affects the features that are like open medium, dynamical changes in topology, lack of central monitoring and management and it not obtain the clear defence mechanism to MANETs. To prevent or detect malicious nodes launching collaborative wormhole attacks is a challenge. The existing system designs a dynamic source routing (DSR)-based routing mechanism, but it is also referred to as the cooperative bait detection scheme (CBDS) to detect the wormhole attacks effectively. Here we describes the various wormhole attacks and prevention methods for wormhole attack.

Opis:
Mobile Ad-hoc Networks (MANETs) are widely used nowadays. Because of their characteristics as open media, dynamic topology, being infrastructure-less and lack of centralized monitoring, MANET is vulnerable to a wide range of attacks like blackhole and grayhole. Blackhole and grayhole attacks refer to the attacks that breach the security by performing packet forwarding and routing misbehavior and cause denial of service in MANETs. In this paper we improved our previous work on MCBDS, we reduced false-positive rate more than before and on average it dropped to zero. The proposed method employs Network Simulator-2 (NS-2) to validate the effectiveness under different scenarios. Simulation results show that improved MCBDS has same performance as CBDS in terms of throughput and end-to-end delay and as much as the presence of malicious nodes increased, improved MCBDS performs better than CBDS.

Opis:
The consensus problem for a class of high-order nonlinear multi-agent systems (MASs) with external disturbance and system uncertainty is studied. We design an online-update radial basis function (RBF) neural network based distributed adaptive control protocol, where the sliding model control method is also applied to eliminate the influence of the external disturbance and system uncertainty. System consensus is verified by using the Lyapunov stability theorem, and sufficient conditions for cooperative uniform ultimately boundedness (CUUB) are also derived. Two simulation examples demonstrate the effectiveness of the proposed method for both homogeneous and heterogeneous MASs.
