A group of wireless devices with the ability to sense physical events (sensors) or/and to perform relatively complicated actions (actors), is referred to as Wireless Sensor and Actor Network (WSAN). In this work, we propose and implement two Fuzzy Based Actor Selection Systems (FBASS): FBASS1 and FBASS2 for actor selection in WSANs. The systems decide whether the actor will be selected for the required...
Wireless Mesh Networks (WMNs) are attracting a lot of attention from wireless network researchers, because of their potential use in several fields such as collaborative computing and communications. In this paper, we present the implementation of a testbed for WMNs using Raspbian OS. We analyze the performance of Optimized Link State Routing (OLSR) protocol in an indoor scenario. For evaluation we...
We propose a Heterogeneous Multi Domain (HMD) architecture and protocols that uses ad hoc and cellular communications for enabling the exchange of information among users and smart environments. In particular, we focuss on the data communication and information diffusion related to tourism industry. Sensor's technology enables today the collection of various data related to the environment, such as...
A group of wireless devices with the ability to sense physical events (sensors) or to perform relatively complicated actions (actors), is referred to as Wireless Sensor and Actor Network (WSAN). In WSANs, sensors gather information about the physical events, while actors perform appropriate actions upon the environment, based on the sensed data shared by sensors. In order to provide effective sensing...
Cluster formation and cluster head selection are important problems in sensor network applications and can drastically affect the network's communication energy dissipation. However, selecting the cluster head is not easy in different environments which may have different characteristics. In order to deal with this problem, we have proposed a power reduction algorithm for sensor networks based on...
Wireless Mesh Networks (WMNs) are currently attracting a lot of attention from wireless research and technology community due to their importance as means for providing cost-efficient broadband wireless connectivity. WMNs are based on mesh topology, in which every node is connected to one or more nodes, enabling thus the information transmission in more than one path. In this paper, we propose a system...

We introduced the localization algorithm to find the coordinates of nodes in WSN. The proposed algorithm starts at measuring the angle and distance at the landmark and their neighbors and then finding their azimuths and incident angles. In this paper, four kinds of the method to calculate and update the coordinates of nodes are proposed. The simulation results show that to utilize more data obtained...
Wireless Sensor Networks (WSN) are a sensing, computing and communication infrastructure that are able to observe and respond to phenomena in the natural environment and in our physical and cyber infrastructure. The sensors themselves can range from small passive micro sensors to larger scale, controllable weather-sensing platforms. In this work, we investigate how the sensor network performs in the...
