TItle: Mobility for enhanced performance in sensor networks

Description: Sensor Networks are being deployed to sense the environment. The data sensed(collected) at the various nodes is relayed to a base station using the wireless multihop network formed by the sensor nodes. The nodes nearer to the base station, acting as relays, risk running out of battery earliest. Once they die, the network becomes disconnected. I am looking at using controlled mobility to gather data from the sensor nodes. If the delay in data can be tolerated, the mobile element can visit these nodes periodically and get their data, thus reducing the relaying and increasing the lifetime. Recent research has involved deciding how and where the mobile should go.
