Abstract EN
The wireless sensor network (WSN), consisting of a large number of microsensors with wireless communication abilities, has become an indispensable tool for use in monitoring and surveillance applications.
Despite its advantages in deployment flexibility and fault tolerance, the WSN is vulnerable to failures due to the depletion of limited onboard battery energy.
A major portion of energy consumption is caused by the transmission of sensed results to the master processor.
The amount of energy used, in fact, is related to both the duration of sensing and data transmission.
Hence, in order to extend the operation lifespan of the WSN, a proper allocation of sensing workload among the sensors is necessary.
An assignment scheme is here formulated on the basis of the divisible load theory, namely, the energy dependent divisible load theory (EDDLT) for sensing workload allocations.
In particular, the amount of residual energies onboard sensors are considered while deciding the workload assigned to each sensor.
Sensors with smaller amount of residual energy are assigned lighter workloads, thus, allowing for a reduced energy consumption and the sensor lifespan is extended.
Simulation studies are conducted and results have illustrated the effectiveness of the proposed workload allocation method.
