Improving Performance Using Mobile Data Collectors in Wireless Sensor Networks

Sensor networks are characterized by limited energy, processing power, and bandwidth capabilities. These limitations become particularly critical in the case of event-based sensor networks where multiple collocated nodes are likely to notify the sink about the same event, at almost the same time. The propagation of redundant highly correlated data is costly in terms of system performance, and results in energy depletion, network overloading and congestion. Data aggregation is regarded as an effective technique to reduce energy consumption and prevent congestion.
