Wireless Sensor Networks (WSNs) have become a hot research topic in academia as well as in industry in recent years due to its wide range of applications ranging from medical research to military. In this paper, we study the effect of mobile sink and mobile sensors in WSN performance. The WSNs should allow a systematic deployment of sensor nodes including mobility among the sensor nodes. The disseminated...
Wireless Sensor Networks (WSNs) have become a hot research theme in academia as well as in industry in recent years due to its wide range of applications ranging from medical research to military. In this paper, we study the effect of IEEE 802.15.4 MAC standard on the performance of AODV protocol for WSNs environment with mobile sensors. The WSNs should allow a systematic deployment of sensor nodes...
The Wireless Sensor Networks (WSNs) have a wide range of applications such as target detection and tracking, environmental monitoring, and tactical systems. However, lower sensing ranges result in dense networks, which brings the necessity to achieve an efficient medium access protocol subject to power constraints. Various MAC protocols with different objectives were proposed for wireless sensor networks...
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. We investigate how the sensor network performs in these cases. We used the good put and consumed energy metrics for performance evaluation. From simulations, we have shown that the good put of multimobile...
Sensor networks are 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.

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,...

In this paper, we investigate how the sensor network performs in the case when the event moves with special movement path. We compare the simulation results for four scenarios: when the event is stationary, moving randomly, moving with simple 4 path and boids path. The simulation results have shown that for the case when event is moving randomly the performance is the worst in the four scenarios....

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...
