摘要:
Sensor nodes will transmit the sensed data to sink by multi-hop strategy in wireless sensor networks. However, this will cause the hotspot problem and also decrease the effectiveness ofthe sensed data in larger networks environment. We proposed data transmission mechanism with mobile sinks using timestamp in wireless sensor networks to solve the above problems. We assume that all mobile sinks are synchronized and equipped with the timer. Mobile sinks will periodically update the timestamp of sensor nodes. After that. sensor nodes will decide to broadcast the sensed data or not by comparing the timestamp when event occurred
