ABSTRACT
Mobile sinks in wireless sensor networks require an additional communication mechanism of geographic routing. Because the sink?s location as the destination in geographic routing is changed dynamically, sinks? location should be propagated continuously though the sensor field for sensor?s future data report. However this frequent location updates can drain up the sensor?s battery power and increase wireless channel contentions. <p>As a support to the mobile sinks, we proposed locators for mobile sinks that track current sinks? location. If a sensor reports sensed data to sinks later, it can acquire sinks? location from the locators. The locators are uniformly distributed uniformly to the sensor fields by hash bashed structured replication. Sinks update own location only immediate locators and other locators are fed location information by locators self location propagation.</p> <p>We implemented our locator protocol with Network simmulator-2 and compared previous work TTDD, a Two- Tier Data Dissemination. Our results show that locators handle multiple source environments with low overhead of location acquisition process.</p>
