APPARATUS AND METHOD FOR EVALUATING WIRELESS SENSOR NETWORKS

摘要

A method for evaluating performance of a sensor network. The method includes selecting, a sensor distribution pattern for a geographical region and determining a location for a base station. A plurality of sensor clusters are generated, each sensor cluster being formed by one of a first and second grouping mechanism. Further, the method allocates, for each sensor a time-slot within a time-frame to transmit a data packet from the sensor to the base station, and evaluates the performance of the first grouping mechanism and the second grouping mechanism for the selected sensor distribution pattern and base station location, by computing at least a ratio of delivered data packets to the base station to a total energy consumption, and a first delay and a second delay incurred by each data packet.

1. A method of operating a computer system to determine the performance of a wireless sensor network, the method comprising:
selecting, a sensor distribution pattern for a geographical region where the sensors are to be deployed; determining a location for a base station in the geographical region; generating by circuitry, a plurality of sensor clusters, each sensor cluster of the plurality of sensor clusters being formed by one of a first grouping mechanism and a second grouping mechanism, the first grouping mechanism forming the sensor cluster based on a strength of a signal transmitted by each sensor, that is received by the base station, and the second grouping mechanism forming the sensor cluster based on a location of the sensor and an energy level of the sensor; allocating, for each sensor included in the generated sensor cluster, a time-slot within a time-frame corresponding to the sensor cluster, the time-slot being utilized for transmitting a data packet from the sensor to the base station; and evaluating by circuitry, the performance of the first grouping mechanism and the second grouping mechanism for the selected sensor distribution pattern and base station location, by computing at least a ratio of delivered data packets to the base station to a total energy consumption, and a first delay and a second delay incurred by each data packet.
