In these protocols, the routing decision, at each sensor node, is based only on the positions of the destination node and forwarding node's neighbors. However, these protocols are based on exact sensors position, assuming that sensors are equipped with a geographic positioning or a localization-based technique. Recently, several techniques, such DV-Hop, have been proposed for estimating sensors' positions. This paper introduces an integrated geographic routing protocol by integrating both sensors' position estimation and geographic routing techniques. We have mainly combined DV-Hop for estimating sensors position and the greedy perimeter stateless protocol for data forwarding and routing. Simulations have been carried out and results are reported to show the efficiency of the proposed hybrid geographic routing protocol in WSNs.

If sensors are accurately located, the identified event (e.g., fire, accident) could be of most important in order to figure out and understand the context or situation. However, sensors localization is still an important issue in order to develop context-driven applications. This paper introduces a new scheme for sensor nodes localization in three-dimensional WSNs, denoted 3DeDV-Hop. We have implemented both algorithms the 3DeDV-Hop and 3DDV-Hop in OMNET++, and studied their performance in three dimensional wireless sensor networks. Simulation results show that the 3DeDV-Hop outperforms the basic 3DDV-Hop localization algorithm in terms of localization accuracy and the number of localized nodes.

Several localization techniques have been introduced to provide position of sensor nodes, but a limited number of these algorithms have been proposed to accurately estimate the location of sensor nodes for mobile wireless sensor networks for three-dimensional. In this paper, we propose localization algorithms for mobile nodes in 3D. The algorithms based on DV-Hop and EDV-Hop techniques. The selected model is Random Way Point Mobility model. Our presented algorithms guarantees that the nodes estimate their own position with a butter localization accuracy in comparison to static scenarios. Moreover, the proposed simulation confirms that the introduced algorithms can significantly improve the localization error and localization coverage of algorithms in Mobile Wireless Sensor Networks for nodes in a Three- Dimensional.

The location of sensors is a major issue in these networks. Many localization algorithms have been proposed and can be categorized into two families: range-based and range-free algorithms. In this paper, the localization algorithm DV-Hop is improved in order to minimize the estimation error and thus obtain better localization accuracy of sensor nodes. Simulations have been conducted and results are reported to show the efficiency of the enhanced version of DV-Hop

This work reports the most representative studies about the inclusion of ICT applications for the target users and aims to derive practical guidelines on this aspect by exploring the experience of Arabic readers with and without dyslexia when using online text which is based on a user study with a group of 32 users (12 users with dyslexia). The data collected analyses spelling errors faced by Arabic learners. The comparison between the experience of learners with and without dyslexia has yielded insights into the need to consider features of the Arabic language that account for the unique needs of users with specific learning disabilities.
