Localized Sensor Area Coverage with Low Communication Overhead

The project explains about many localized sensor area coverage protocols regarding heterogeneous sensors. Every sensor has been mentioned along with its arbitrary sensing and transmission radii. The every single sensor consists of some limited time cycle that can receive messages from the specific nodes only in the limited time which has not completed.

After the due time of expiry it will not receive or hear any messages. The sensor node which is not completely surrounded sensing area i.e., or partially surrounded with some group of active sensors still active for some required time informing it by giving out message before become inactive. Our project makes this sensor to remain active till the sensor   active or not surrounded.  The covered nodes will be in the dormant stage by some time generating a leaving message to the sensor about its situation. Depends on the other sensor response the inactive sensor takes decision to be covered or still remain active. 

The Existing System 

The existing system has demerit of not having status links with other sensors. Because of the improper interaction between sensors the competition and data missing occurs. The cause of this demerit is improper use of the source. The affluent network is unable to surround the place of linked groups of active nodes. Therefore the nodes are not judging about the particular communicating node. 

The Proposed System 

The presented project overcomes this problem of improper communication between sensors. The sensors now posses the figure of the communicating device at the same time. So every sensor has ability to communicate or interact with other sensor or whole network. The less life time sensor with coverage, observes other sensors availability and given the job to the specific sensor. This system is very working and vigorous as it covers more area by using the limited active sensors and also the longstanding connection. However it may loss some messages. 

The Proposed system can be operated in Window XP. The software programs required for the application development are Microsoft Visual Studio.Net 2005 for the front end and Visual C#.Net for the Coding language. It requires Pentium III 700 MHz processor, 40 GB hard disk drive and 128 MB RAM.
