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,...
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 how the sensor network performs in the case when three events move with special movement path. We compare the simulation results for three cases: stationary, random and simple...
In this work, we investigate how WSN performs in the case when sink node moves using different radio models and metrics. We consider routing efficiency, delay and number of received packet metrics to evaluate the performance of WSN using AODV routing protocol, lattice topology, and TwoRayGround and Shadowing radio models. We evaluate the performance of WSN by simulations. The performance evaluation...
In this paper, we consider the behavior of a wireless sensor network for TwoRayGround and Shadowing radio models for the case of mobile event. By means of simulations, we analyse the performance of AODV protocol. In the previous work, we considered that the event node is stationary in the observation field. In this work, we want to investigate how the sensor network performs in the case when the event...
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...
