چکیده مقاله:

Life time and Energy Efficiency are important factors in the design of wireless sensor network. A critical issue during data collection is the formation of energy holes near the sink. Sensorsnear the sink have to participate in relaying data on behalf of other sensors and thus their energy will be depleted very quickly. Themobile sink movement yields the significant performance gained through decreasing the amount of energy consumption. In thisstudy, we propose a Grid Based approach for Data Disseminating to the Mobile Sink in Wireless Sensor Network. In this method noenergy is consumed to construct the virtual substructure and there no overhead is being constrained to the nodes. In this method (GH)grid heads are responsible for data dissemination; hence rest ofthe nodes change to idle mode and network life time increases. Also, our data dissemination protocol is simple and has very lowoverhead to build and maintain. We have presented a new method for sink location update which leads to least cost for data transfer to the sink. Simulation results illustrate that presented protocol decreases energy consumption up to 30%.
