Sensor networks 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. In this paper, we investigate packet loss, routing loss and transport loss in mobile Wireless Sensor Networks (WSNs) considering AODV protocol and different radio models. We compare the simulation results...
In this work, we carry out a comparison evaluation for mobile and static sensor nodes in Wireless Sensor Networks (WSNs) using TwoRayGround propagation model and different protocols. We consider packet-loss and delay metrics to evaluate the performance of WSN. The simulation results have shown that for WSN with mobile sensor nodes, the delay is better than static sensor nodes. In case of static sensor...
In this paper, we implement a simulation system for single and multi-mobile sinks in wireless sensor networks considering TwoRayGround and Shadowing propagation models, using DSR routing protocol.

Barrier coverage that requires much fewer sensors than full coverage, is known to be an appreciate model for detection applications. Early results have shown how to construct barriers by both randomly and planned deployment in belt regions. In randomly deployment condition, there may be more than one barrier in a belt region. We present a solution for sliding barriers among the sensors that are deployed...
Event detection is a major issue for applications of wireless sensor networks. In order to detect an event, a sensor network has to identify which application-specific incident has occurred based on the raw data gathered by individual sensor nodes. Sensor networks are a sensing, computing and communication infrastructure that are able to observe and respond to phenomena in the natural environment...
In this paper, we evaluate the performance of WSNs for single and multi mobile events using Two Ray Ground radio model and AODV protocol. We consider good put and routing efficiency metrics to evalute the performance of WSN. The simulation results have shown that for single mobile event, the good put is better than multi mobile events when the number of sensor nodes is higher. In case of boids model,...

Presently, there are many research work for sensor networks. In our previous work, we implemented a simulation system for sensor networks. But, we considered that the event node is stationary in the observation field. However, in many applications the event node may move. For example, in an ecology environment the animals can move randomly. In this work, we want to investigate how the sensor network...
