Designing the self-balancing two-wheeled mobile robots and reducing undesired vibrations are of great importance. For this purpose, the majority of researches are focused on application of relatively complex control approaches without improving the robot structure. Therefore, in this paper we introduce a new two-wheeled mobile robot which, despite its relative simple structure, fulfills the req...

The paper presents an analytical model for a GSM-based cellular mobile network that applies the Intelligent UnderOverlay (IUO) scheme to increase the capacity by increasing the frequency reuse while maintaining the service quality. The IUO is a multi-layer cell structure that is based on dividing the frequency band into the super layer and the regular layer frequency group. The super frequencie...

Mobile autonomous platforms are considered as mobile nodes in a collaborative wireless sensor network to estimate environmental parameters like temperature, humidity, pressure, sunlight and position. These small robots are equipped with cheap and energy efficient sensory module, based on MTS420 environmental sensor board. For a better approximation of the reality, statistical indicators like sa...

Mobile Ad hoc Network (MANET) is an autonomous, self-configuring and infrastructure-less system in which various mobile nodes are connected by wireless links. In Mobile Ad Hoc Network (MANET), various routing protocols are there like AODV, DSDV, TORA, DSR etc. Due to the nature of changing topology and infrastructure less in MANETs there are various issues and constraints which affect the perfo...

M-commerce (mobile commerce) is the buying and selling of goods and services through wireless handheld devices such as cellular telephone and personal digital assistants PDA. M-commerce provides lot of services like Mobile ticketing, Mobile banking, Mobile location based services, Mobile auctions, Mobile purchasing and so on. This represents an incredible opportunity to enable mobile devices, a...

PDA’s (Personal Digital Assistant) and mobile phones have become multitasking devices that provide an enormous potential in various fields, including HACCP. We have designed a record taking software in order to be used in small food catering establishments, like canteens or restaurants. It’s developed for Windows Mobile for use in mobile devices such as PDA’s and Smartphone’s. It enables the cr...

6 Next generation wireless communication systems will consist of a large number of mobile or static terminals and should be 7 able to fulfill multiple requirements depending on the current situation. Low latency and high packet success transmission rates 8 should be mentioned in this context and can be summarized as ultra-reliable communications (URC). Especially for domains 9 like mobile gamin...

The social transformations brought about by the mobile internet are extensive. In discussing the broad range of these transformations—positioned as a shift from personal computing to pervasive computing—this editorial elaborates on the key contributions addressed by the articles in this special issue of Future Internet. These articles touch on topics such as the digital divide, the role of the ...

Mobile Ad hoc Networks comprises of mobile nodes that are communicating via either singlehop or multi-hop wireless links through a sequence of intermediate nodes. They are an autonomous collection of mobile hosts connected by wireless links with no fixed infrastructure. A unicast communication provides an efficient connectivity between the source and destination through intermediate mobile node...

background: a lot of investigations exist on the biological effects of radiofrequency and microwave radiation however only a few studies have considered non-carcinogenic exposure to radiations specifically from mobile phones. objectives: to introduce some subjective neurological symptoms in mobile phone users. materials and methods: in this cross-sectional descriptive study conducted from march...
