SUMMARY In Wireless Sensor Networks (WSNs), sensor nodes consume their limited battery energy to send and receive data packets for data transmission. If some sensor nodes transmit data packets more frequently due to imbalance in the network topology or traffic flows, they experience higher energy consumption. And if the sensor nodes are not recharged, they… (More)
In Wireless Sensor Networks (WSNs), sensor nodes consume their limited battery energy for data transmission. Especially, the clustered sensor nodes in clustered sensor networks nearer the sink need to transmit data packets more frequently, because those functions as both sensor data generator and routers for data transmissions of other sensor nodes;… (More)
The distinctive features of OBS affect transport protocols which take in charge of end to end transmission. This paper evaluates the performance of the transport protocols in OBS networks under how to be assembled. We present the throughput for 1) coexisted TCP bursts and UDP bursts, and 2) bursts containing TCP and UDP packets.
