We develop a daily menu assistance system which is built to give a suggested daily menu based on daily calories need. In this paper, we design a recommendation feature using fuzzy ontology to give menu recommendation by few factors, such as price, rate, vote and taste, since so many menus are suggested. Protege, SWRL (Semantic Web Rule Language) and SQWRL (Semantic Query-Enhanced Web Rule Language)...
Security in Wireless Sensor Networks (WSNs) is especially challenging and quite different from traditional network security mechanisms. There are two major reasons. Firstly, there are severe constraints on these devices namely their minimal energy, computational and communicational capabilities. Secondly, there is an additional risk of physical attacks such as node capture and tampering. Moreover,...
Intrusion detection system (IDS) is a crucial part of network security area and is widely employed. Signature-based matching mechanisms require a completed analysis of attack patterns and the availability of knowledge detection beforehand. To cope with new attacks, IDS tools require to be continuously updated with the signature rules. In this paper, we present anomaly detection technique by using...
In this paper, we propose a scheme for improved performance of resource reservation and call admission control for cellular networks called Predictive User Mobility Behavior (PUMB) scheme. This algorithm is proposed in which bandwidth is allocated more efficiently to neighboring cells by key mobility parameters in order to provide Quality of Service (QoS) guarantees for transferring traffic. The cell...
The daily useful nutrition needs become important information to be given to the society. Occurrence of many nutrition cases, such as obesity, overweight or even underweight, shows that the society have not been given an appropriate information about their recommended daily values for key nutrients and also the suggestion of their daily menus. In this paper, we design ontology-based daily menu assistance...
Presently, the wireless sensor networks (WSNs) are widely used in many areas of communication systems and its security system becomes very important. However, the security mechanism for WSNs has to be considered differently from traditional network. Firstly, there are severe constraints on WSNs devices such as minimal energy, computational and communicational capabilities. Secondly, there is an additional...
In this paper, we propose a scheme for improved performance of resource reservation and call admission control for cellular networks called predictive mobility support demand (PMSD) scheme. This scheme is proposed in which bandwidth is allocated more efficiently to neighboring cells by key mobility parameters in order to provide QoS guarantees for transferring traffic. The probability is used to form...
Wireless sensor networks (WSN) have received a lot of attention recently due to their enormous potential in different applications. Many applications in WSN require time synchronization among all the sensor nodes. However, in practice, network do normally have some abnormal nodes (we called Fault Clock Node or FCN), which could cause high synchronization error. In this paper, we present a light-weight...
One important application for mobile robot is the ability to send most real visualization to the viewer. The possible algorithm is the stereoscopic application that consists of data from left and right views. Therefore, the left and right image pairs have to be transmitted simultaneously in order to display 3-dimentional video at the remote site. Moreover, due to the twice data in comparing with a...
In this paper, we have proposed an approach of negotiation protocol for services agreement between two wireless nodes in ad hoc networks. Protocol principles are based on peculiarities of mobile nodes and mobile users on MANET, i.e., user autonomy, node functionality and resource management. Mobile users can use this negotiation protocol for defining its network functions in MANET based on their policy...
All communications in a network made by mobile hosts through a shared radio link without cable or backbone, commonly called mobile ad hoc network (MANET). Since the network topology may change constantly because of mobility of nodes and the available routes may fail many times, quality-of-service (QoS) of real-time multimedia application may have difficulty in satisfying their services. In this paper,...
Ad hoc network is a set of mobile nodes that each mobile host is able to move freely and the network is unpredictable topologies transformation. Therefore, the searching for transmission path becomes difficult and complicated. Because each mobile host in ad hoc network acts as a switching node that routes and forward packets to its neighboring mobile hosts (or nodes), hop by hop, or multi-hop. Unlike...
This paper studies routing and wavelength assignment in wavelength-routed (WR) optical WDM networks which are circuit-switched in nature. When a session request is given, the hard task of routing and wavelength assignment (RWA) is to calculate the satisfiable path between two nodes, and also to assign an available set of wavelengths along this path. Therefore, we have proposed a new routing and wavelength...
