EWSN BASED RELIABLE TRANSMISSION USING MOBILE DATA COLLECTOR NODE

The most important goal in event driven wireless sensor network is to transmit the event information to users as soon as possible. In typical WSN there are number of sensor nodes which detect the event and transmit data packet towards static sink, but the node which are one hop from the sink at this location there lot of chances of both network or congestion, this leads to reduce the energy and data loss (Packet drop).In our EWSN model we use mobile data collector that will collect the event information and send it to sink. sensor node sense the event and announce by broadcasting the alarm packet, when data collector node receive this packet it will find out location and collect data from that sensor node .and by using the concept of travelling Salesmen Problem it will find the route to the Sink node and deliver the packet there for further processing. So by using technique we try to avoid the congestion near to sink and try to improve the reliability of the network.
