An Energy Balanced Data Collection Mechanism for Maximizing Throughput using Uncontrolled Mobile Sink in WSNs

Data collection in the wireless sensor networks has become one of the important research topics. In literature, many studies proposed algorithms for data collection using mobile sink. These studies can be further classified into two types according to the mobility of the sink. This paper considers the bus as the mobile sink and presents a distributed data collection algorithm for collecting maximal data from sensors and extending lifetime of the wireless sensor network. Performance evaluation reveals that the proposed Energy Balanced Data Collection (EBDC) mechanism achieves better throughput and longer network lifetime than existing mechanisms.
