The tradition technologies still suffer from two problems: performance and security efficiency. The existing research has serious drawbacks when using public-key mechanisms such as digital signature algorithms. In this paper, we propose Reliable and Efficient Integrity Scheme for Data Collection in HWSN (REISCH) to alleviate these problems by using secure and lightweight signature algorithms. The results of the performance analysis indicate that our scheme provides high efficiency in data integration between sensors and server (saves more than 24% of alive sensors compared to traditional algorithms). Additionally, we use Automated Validation of Internet Security Protocols and Applications (AVISPA) to validate the security procedures in our scheme. Security analysis results confirm that REISCH is safe against some well-known attacks.

The absence of any fixed infrastructure in mobile ad-hoc networks makes it difficult to utilize the existing techniques for network services, and poses number of various challenges in the area. The discovery and maintenance of secure route is the most flinty challenge. In this paper, we deliberate and implement one secure routing protocol FLSL (Adaptive Fuzzy Logic Based Security Level Routing Protocol) and study its performance under different scenarios. The implementation of FLSL protocol has been carried out by use of NS-2. Various experiments results from simulation verify the protocols, also demonstrate the feasibility of the protocol. A set of experiments under different scenarios have been presented and results of these experiments have been analyzed.

A MANET is characterized by no fixed infrastructure or varying topologized structure. This feature allows MANET to be deployed within many circumstances where traditional IP networks are constrained or too expensive in terms of time and resources. Adversely, the mobility of node renders MANETs vulnerable to many

In recent years, many educators adopt computer simulation technology in the teaching of some topics or courses which include dynamic interactions between components. For years, many concepts of networking have been taught based on textual or other static visual materials. And many researcher have shown that illustrating dynamic scenario using static and lecture-based paradigms compromises the teaching effectiveness. This problem on computer network education prompted us to use graphical simulation. Courses related to computer communication and networking can be benefitted if computer simulation is wisely adopted. In this paper, we describe a study in which we count on computer simulation to illustrate important and complicated algorithms of congestion control and queue management in the TCP/IP protocol suites. Comparing with current queue management techniques, Active Queue Management(AQM) is an innovative mechanism in router packet scheduling. We noticed that AQM is a promising technique and might be implemented in new generation routers. However, the concepts and internal workings of AQM schema are difficult for researchers and students to understand. Thus, we designed an interactive software to dynamically visualize the AQMs' principles and internal workings. The implementation of simulation package used Java technology due to that Java is an object-oriented programming language with extensive build-in graphical facilities and multi-threading mechanism. In our software package, we have implemented the traditional Drop Tail(DT) and two representative AQM schemas: Random Early Detection(RED) and BLUE. It allows users to conduct their own experiments by entering different parameters for each of the algorithms, as shown in the figure below. The structure of simulation package follows the Model-View-Controller paradigm which separates the development of network models from visualization and control of the models. The animation visually describes the internal working process of the algorithms with a plot diagram, which displays the variations of the router queue size. We also compared the simulation results of the three queue management algorithms. From the animating simulation, we can easily see the difference of performance between AQM and DT. The main strength of our AQM simulator is ease of use when compared with other professional simulation tools such as NS2 or OMNet++, because users do not need solid programming capability to build the simulation from scratch. By using graphical animation, learners can directly access the internal process of the three queue management algorithms. We have received very positive feedbacks from network professionals and University lecturers for using this simulation software.

To participate in SNG, a network has to share a secret key with one member of the SNG. The shared secret key will be used to set up an encrypted channel between the network and the SNG member. It is imperative to authenticate the data sent through the encrypted channel. This paper uses the symbols and approached presented by Lampson in his paper [15] to provide a formal proof of how encryption channel authenticates itself in SNG. It forms the basis of using encrypted channels in SNG.

Service Path (SPath) holds the authentication and server paths along side with service information. As the number of hops in a redirection increases, the length of SPath increases. The overhead for service routing protocols which uses SPath increases with the length of SPath. Hence it is desirable to optimize SPath to ensure efficiency and scalability of protocols involving service routing. In this paper, we propose a rerouting strategy to optimize service routing, and demonstrate how this strategy can be implemented using SPath to enhance the efficiency and scalability of Service Network Graph (SNG).

AODV floods the network with control messages to discover a route to the destination, which often results in a large number of control packets traveling through the network. This paper introduces the design and implementation of GeoAODV routing protocol for OPNET Modeler. GeoAODV takes advantage of Global Positioning System (GPS) coordinates to only search the area where a path to the destination is likely to be located. This paper discusses the authors' endeavors to develop a model of GeoAODV protocol and seamlessly integrate it within OPNET Modeler. In addition the paper provides an overview of OPNET Modeler's software architecture for modeling wireless networks and MANET routing protocols.
