In this paper, we study WSN design, as a multi-objective optimization problem using GA technique. We study the effects of GA parameters including population size, selection and crossover method and mutation probability on the design. Choosing suitable parameters is a trade-off between different network criteria and characteristics. Type of deployment, effect of network size, radio communication...

The unreliability and dynamics of mobile wireless sensor networks make it hard to perform end-to-end communications. This paper presents a novel source-initiated on-demand routing mechanism for efficient data transmission in mobile wireless sensor networks. It explores the Thorup-Zwick theory to achieve source-initiated on-demand routing with time efficiency. It is able to find out shortest rou...

The introduction of mobile devices into wireless sensor network systems has attracted significant attention in recent years. Mobile devices can provide a bridging mechanism to connect geographically separated sensor networks, forming a global coverage sensing network. However, effective techniques for organizing multiple mobile devices and supporting coordinated sensor-data sharing have not yet...

At the present stage wireless sensor network exists some deficiencies such as finite energy, limited communication capability, multi-hop routing and dynamic topology. In addition too many nodes which are distributed intensively influence also performance of wireless sensor network. Besides distributed optimization problem always impact to efficiency of the network. For data processing and routi...

In recent years, remote environment monitoring has been significantly improved with wireless sensor networking technology. This paper presents the real time streaming of an indoor environment using a wireless sensor network and a set of self-navigating robots. Mobile robots with mounted sensors will autonomously navigate through an indoor area with unknown obstacles. The robots will be able to ...

Nowadays most of the wireless sensor network management modes have a shorter lifetime because adopting the way of transferring management information to each other, which thus consuming energy too fast. This paper Present a new modal based on mobile agent for wireless sensor network scluster management.this model can make up the shortcoming of the nowadays wireless sensor networks management ar...
