The Mobile Ad-hoc Network (MANET) is constructed based on wireless medium and it is of self organizing manner. MANET is simple to set up and has changing topology. The mobile Ad-hoc networks are in danger of different attacks because MANET operational environment is open and dynamic. In MANET, data transfer use the different Routing protocols. Selfish (Malicious) node work is completely different as compared to normal Mobile nodes. Malicious nodes have capability to remove or modify the Routing Information. It also sends the fake Route Request to access user's data. It is responsible for attacks on the existing normal mobile nodes and creates receiver collision, restricted transmission power, fake misbehavior etc. Malicious node carries different types of attacks on the networks so it directly or indirectly effects the routing Performance. The intention of this work is to check and analyze the Network performance in malicious environment and provide prevention for the attack. Throughput and Delay are analyzed for Denial of Service (DoS) attack and prevention scenarios. © Springer International Publishing Switzerland 2014.

A method aimed at refinement of the cyclic steady state space reachable in the given multimodal transportation network is proposed. The paper introduces the concept of a System of Concurrent Multimodal Cyclic Processes in which several subnetworks interact each other via distinguished subsets of common shared workstations as to provide a variety of demandresponsive work-piece transportation/handling services. Searching for the cyclic steady state behavior the following question is considered: Is the cyclic steady state space reachable in the given network structure ? The declarative approach employed makes it possible to evaluate the reachability of cyclic behaviors on a scale that reflects real practice. © Springer International Publishing Switzerland 2014.

The demand-side energy management of microgrids comprising of buildings of heterogeneous nature (residential, commercial, industrial, etc.) and thus exhibiting heterogeneous occupancy pattern, requires the development of appropriate energy management systems (EMSs) that can integrate the maximum exploitation of the distributed energy resources like photovoltaic panels with the thermal comfort of the occupants. This paper presents a simulation-based optimization approach for the design of an EMS in grid-connected photovoltaic-equipped microgrids with heterogeneous buildings and occupancy schedules. The EMS optimizes a multi-objective criterion that takes into account both the energy cost and the thermal comfort of the aggregate microgrid. A three-building microgrid test case is used to demonstrate the effectiveness of the proposed approach: comparisons with alternative rule-based and optimization-based EMSs show that the proposed EMS strategy exploits the occupancy information to automatically change the energy demand of each building, resulting in improved energy cost and thermal comfort.

Cross layer design for video streaming in MANETs

Mobile Ad hoc NETworks (MANETs) are becoming more essential to wireless communications due to growing popularity of mobile devices. However, MANETs do not seem to effectively support multimedia applications and especially video transmission. In this work, we propose a cross-layer design that aims to improve the performance of video transmission using TCP Friendly Rate Control (TFRC). Our design provides priority to video packets and exploits information from the MAC layer in order to improve TFRC's performance. The proposed cross-layer design utilizes SNR measurements along the routing path, in order to make the route reconstruction procedure more efficient. Simulation results show that both the use of traffic classification and the SNR utilization lead to important improvements in terms of end-to-end Quality of Service (QoS). © 2014 Academy Publisher.

In this paper, we determine optimal topology update interval for fault tolerant k-edge connected topology update algorithm Local Tree-based Reliable Topology (LTRT) used in Mobile Ad-hoc Networks (MANETs). Topology update algorithms are periodically run on each participant node of MANET. This period called topology update interval (Δt), is chosen to be uniform. However, neither a high nor a low value of Δt is suitable for a MANET due to unpredictable moving speed of nodes and connectivity ratio and power consumption restrictions. In this paper a method is proposed to dynamically determine the optimal value of topology update interval for k-edge connected topology control algorithm LTRT used in MANETs. The proposed method automatically determines the appropriate value of Δt while ensuring the required connectivity ratio of the whole network for a given node speed and energy consumption goal. The results show that the dynamic method can enhance the network connectivity, allow higher moving speed and improve the performance of network on the same cost, in terms of transmission range that is directly related to power consumption.

Over the recent past years research effort has been dedicated towards addressing a generic solution in System of Systems (SoS) control problems. Two are the main obstacles that have to be bypassed in such problem cases, especially in real life applications, rendering the optimization problem into a complicated/challenging one: (i) modelling/simulation tools are usually used in order to construct an as-close-as-possible to reality accurate model, whose construction though requires a considerable amount of time and effort and (ii) furthermore, standard control system designs when applied to SoS exhibit poor performance as they are required to handle very high-dimensional problems. In this paper, we present a first attempt towards addressing these issues. More precisely, a new adaptive optimal control methodology is presented and evaluated. The main attributes of the proposed control methodology is its local nature with minimum requirements for coordination between the constituent system of the SoS and its model-free nature.

Broadband is starting to be deemed by many as a public utility and several countries have already recognized it as a civil right. The European Commission (EC) acknowledging the significance of broadband services for the improvement of citizen welfare and its economic benefits, has put in place targets for the diffusion of broadband to all citizens and businesses in the European Union. This paper, comparatively assesses the current state of affairs in broadband and digital public services in selected South East Europe countries in order to identify weaknesses and highlight strengths and to produce knowledge resources and provide insights that will support informed decision making including strategy and policy planning. It builds on three surveys that took place in the second quarter of 2013 and evidence gathered from seven South East Europe countries. © 2014 IEEE.

The problem of cyclic scheduling of multimodal concurrent processes (MCPs) is considered. Processes composed of sub-sequences of local cyclic processes (LCPs) are treated as multimodal processes, e.g. in case local processes encompass the subway lines network the relevant multimodal processes can be seen as passengers traveling itineraries this network. Since LCPs network implies a MCPs behavior, the following fundamental questions arise: Does the given LCPs network guarantee an assumed cyclic schedule of the MCPs at hand? Does there exist the LCPs network such that an assumed cyclic schedule of MCPs can be achieved? In that context our contribution is to propose a declarative framework allowing one to take into account both direct and reverse problems formulation. © Springer International Publishing Switzerland 2014.
