摘要
Reliable data transmission is desirable in wireless sensor networks due to the high packet loss rate during multi hop transmissions To reliably transmit data for event driven applications packet loss recovery mechanism is needed For loss recovery sensor nodes need to keep packets in their buffers until transmissions successfully complete However since sensor nodes have limited memory packets cannot be buffered for a long period of time This letter proposes an efficient buffer management technique that caches data packets for appropriate amount of time to minimize the resource requirements and at the same time provide reliable data trans mission among sensor nodes
