Tips to show-Achieving Reliability in mobile sensor network

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.

The Data collector aggregates the data arrives from all the nodes and forward it to the Base station .By aggregating the data ,the energy spend for sending the data from the
data collector to the base station is minimized which helps in achieving the reliability. The data collector should select the shortest path to the base station which increases the reliability.
